Best AR-15 Rifles (Updated: 2023)

Let’s talk a bit about my AR 15 top picks! To recap, here’s my top 15 AR 15s list across all price points:

I’d just like to preface this by saying that if a popular AR-15 isn’t on this list, it doesn’t mean that the rifle is no good. This is just based on our own tests.

1. Ruger AR-556 (Best Overall AR-15 for Value)

 

 

 

Since its introduction back in 2014, the Ruger AR-556 has firmly established itself in the AR-15 market as one of the best budget ARs available. The AR-556 is a more inexpensive variant of the SR-556 series of rifles. The primary difference is that the AR-556 is a direct impingement weapon, and the SR-556 is piston driven.

The AR-556 comes coated in a matte black oxide finish for excellent https://nzcasinosonline.co.nz/live-casinos/ rust and corrosion resistance. It comes standard with a 16-inch barrel that is cold hammer forged with ultra-precise rifling for both longevity and excellent accuracy.

The handguards over the barrel and gas tube are built out of glass-filled nylon and are very heat resistant so they can withstand repeated firing. The M4-style synthetic buttstock is easily adjustable with six different positions offered.

Additional features include a forward assist, dust cover, brass deflector, an elevation adjustable fixed front sight, and a Ruger flip up rear sights. The Ar-556 also ships with a front sight tool and a 30-round Magpul PMAG.

We also rank this best AR-15 for easy takedown for DIY.

2. American Tactical Imports, AR-15

 

 

 

Another good option for a budget AR-15 carbine is the American Tactical Imports AR-15 Milsport Ria. This is a mil-spec M4-style AR-15 that comes with a 16-inch M4-profile barrel with a 1:8 twist rate. A flash hider is threaded onto the end of the 5/8×32 TPI muzzle.

The lower and upper receivers are built out of forged 7075 aircraft-grade aluminum. As a mil-spec AR-15, an A2 handguard and collapsible synthetic stock are also installed on the rifle.

This is also an optics-ready AR-15, meaning that it is ready for you to add a red dot or scope to the Picatinny rail on the top of the receiver. There are no sights on the rifle, so you will need to add those yourself if you so desire as well (such as the Magpul flip-up sights).

3. Bravo Company Mod 0,  

 

 

 

All three options are worth looking into, but we like the Mod 0 more because we’ve spent more time with it than others. The Mod 0 is a 16” 5.56x45mm rifle that typically goes for around $1,600.

With a chrome-lined barrel, the Mod 0 was not designed for the gamer, rather it is geared toward tactical applications. But when it comes to training and range shooting, this one packs a lot of punch.

This one includes the aforementioned Magpul MOE handguards and a PNT trigger. For me, it’s the gold standard of modern AR-15s.

The Mod 2 is a quarter of an inch wider than the Mod 0 and shares its cable lock and 5.56mm chambering. It’s also got a mid-length gas system that enables it to run cooler than its counterparts.

The Recce 14/16 is more pricey than the others on this list, generally retailing for $1,500. But it’s a beautiful, streamlined weapon that will definitely be the envy of everyone you encounter at the gun range. The first time I picked one up, I felt like I was in a Predator movie. Seriously, just look at this design:

As with the Mod 0 and Mod 2, the Recce 14 is a 5.56mm caliber rifle with a chrome-lined barrel and 11595E-certified steel. It’s got a Mod 4 charging handle, a Mod 3 pistol grip and a BCM QD end plate.

With a shot peened bolt, feed ramp flat top receiver and chrome lined bore and chamber, it’s a real beast.

4. Wilson Combat – AR-15

 

 

 

 

Even though Wilson Combat is most well-known for their 1911 pistols, they have been making headway into the AR market over the last couple of years too. This is a match-grade AR-15 that comes with a precision rifled barrel built out of stainless steel. The end of the barrel features a Q-Comp muzzle device that does an excellent job of both reducing recoil and the amount of blast that is sent back to the shooter upon firing.

The 2-stage tactical trigger from Wilson is incredibly crisp and has a modular construction design that makes it easy to takedown as well. The carbine also utilizes a mid-length gas system, which Wilson claims helps lend itself to superior reliability.

Additional features of the Wilson Combat Protector worth noting include the BCM pistol grip, high-quality aluminum tactical trigger guard, low profile gas block, M-Lok compatible hand-guard, QD sling mounts, and mil-spec grade upper and lower receivers.

5. Daniel Defense – DDM4 V7 (Best AR-15 for Home Defense)

 

 

 

Daniel Defense is one of the biggest names in the AR world, and they are widely regarded as manufacturing some of the highest quality ARs on the market. The DDM4 V7 features M-Lok attachment technology on the DD MFR XS Rail.

The carbine-length 16-inch barrel is cold hammer forged and comes with a flash hider threaded onto the end of the barrel. Despite this being a carbine, Daniel Defense utilized a mid-length gas system for superior reliability.

An uninterrupted M1913-style Picatinny rail runs along the top of the free-floating MFR XS handguard, with no less than seven M-LOK attachment points. In other words, you have a variety of options for adding sights, accessories, and optics. Meanwhile, the carbine also comes installed with Daniel Defense’s trademark pistol grip and stock.

The ability to add a variety of furniture to this AR and it’s shorter barrel make this the best AR-15 for home defense.  However, keep in mind that .223 can be a problem due to over-penetration.  (See below) Here are some of the best AR-15 ammo options for home defense. If you are looking for the best gun options for home defense, check out the article we wrote about the best shotguns for home defense. 

6. LaRue Tactical PredatAR

 

 

 

We mentioned the Predator movie earlier, right? Well, for those who liked that movie, you’ll appreciate the name of this LaRue model, and it wouldn’t look out of place in a balls-to-the-wall action movie like Predator either.

This one’s got a camo-colored stock, a fierce-looking barrel, and all the things anyone could want in an AR-15. It’s got lightweight maneuverability, sub-MOA accuracy, and staked carrier keys.

7. Rock River Arms LAR-15  Tactical

 

 

At $800-1,000, this is middle of the road expensive AR-15s on this list, and for good reason.

Most people have never heard of the Rock River Arms brand of AR-15 — they’re currently not as popular as the most established brands we grew up hearing, e.g. names like Remington, Smith & Wesson, Sig Sauer, etc.

Rock River Arms was founded in 1993.  They have been steadily earning a solid reputation as an AR-15 manufacturer ever since.

With a Hogue grip and A2 flash hider, the LAR-15 is comfortable to use, accurate, and built to last. It’s got an RRA two-stage trigger and a star safety selector as well.

Although we can’t recommend this rifle to everyone seeing as how hard it can be on the wallet, being a feature-packed piece of hardware, it’s well worth the price — definitely worth taking a look at if you can afford it.

8. SIG Sauer M400

 

 

 

The M400 is billed as being made from some of the finest components and I’d definitely agree with the advertising. It’s got a handsome, classy titanium finish and a direct impingement system.

The thing that makes this the ideal piece for a newcomer to the AR-15 is its ROMEO5 red dot sight.

Though personally, I’m not a real fan of any sight system save for the classic run-of-the-mill iron sights that come pre-installed in most guns, the ROMEO5 sight it comes with will make a huge difference, especially for those who prefer a red dot sight installed on their AR-15 out of the box.

And being manufactured by SIG Sauer, a company known for their firearms’ reliability, for $999.99 you are paying for the company’s reputation and experience. They wouldn’t have won the US Military’s Modular Handgun System contract if their guns aren’t top-notch.

9. Smith & Wesson – M&P15 Sport II (Best AR-15 for the Money)

 

 

 

The Smith & Wesson M&P15 Sport II is one of the most successful budget AR-15s on the market and competes directly with the Ruger AR-556. The M&P style carbines are designed for tactical use and recreational sport shooting alike.

This particular M&P15 Carbine comes with a MOE M-LOK carbine length handguard and a Picatinny-style M-LOK style rail panel. The 16-inch carbine length barrel has a 1:9 twist rate and is coated in a very rust and corrosion-resistant Armornite finish. The firing pin is chromed for superior durability and longevity.

Meanwhile, the M&P15 Sport II comes with a dust cover and a forward assist, two features that were originally lacking in the original M&P15 Sport model. A thirty-round Magpul PMAG ships with each M&P15 Sport II carbine.

10. Springfield Armory – Saint Victor 5.56

 

 

 

The Springfield Armory Saint Victor is a new series of AR-15s in the Saint lineup that was introduced in 2019. A very lightweight carbine at just under seven pounds. Saint Victor is most noted for its Accu-Tite tension bonded flat top forged upper receiver. The 16-inch carbine length barrel is built out of a nice Melonite finish that is very rust and corrosion-resistant.

Meanwhile, the free-floating 15-inch hand guard shields both the barrel and the mid-length gas system. A muzzle brake on the end of the barrel helps to reduce both recoil and muzzle rise. The bolt carrier group is built out of very durable 9310 steel. Spring-loaded flip-up sights also come installed on the rifle for rapid deployment. Both the upper and lower receivers are built out of high-quality aircraft-grade aluminum.

11. SABRE MIL-SPEC COMPLETE AR-15

 

 

Palmetto State Armory is known for their quality materials and construction of their branded AR 15s. First and foremost, the build quality of the SABRE MIL-SPEC is outstanding. It features a sturdy and durable construction, which instills confidence in its long-term reliability. The upper and lower receivers fit together snugly, with minimal play or wobble.

The rifle comes equipped with a 16-inch barrel, which strikes a balance between maneuverability and accuracy. The chrome-moly vanadium construction offers excellent heat resistance and barrel life.

The mil-spec dimensions ensure compatibility with a wide range of aftermarket accessories and parts, allowing for customization to suit individual preferences.  Palmetto State Armory has managed to strike a balance between quality and cost, making this rifle accessible to a wide range of shooters. Despite its budget-friendly price, the SABRE MIL-SPEC does not compromise on performance or reliability.

12. Palmetto State Armory PSA PA-15 (Best Entry Level AR 15)

 

 

If this is your first AR 15 I can’t recommend Palametto State Armory PA 15 enough.  We recently upgraded ours with a new Stock, Handguard and Charging handle from Tyrant Designs.  Looks pretty badass if I do say so myself.

The rifle features a forged 7075-T6 aluminum lower receiver, which provides a solid foundation for the firearm. The upper receiver, constructed from the same material, ensures a secure fit and reduces play or wobble. While the rifle may lack some of the finer details and refinements of higher-end models, it remains sturdy and dependable.

The PA 15 features a standard A2 flash hider, which effectively reduces muzzle flash and recoil. The carbine-length gas system ensures reliable cycling and smooth operation. While the recoil is noticeable, it remains manageable, allowing for quick follow-up shots.  Again, because of the mil-spec dimensions, you can upgrade this rifle all day long.

13. Bushmaster XM15 A3 M4 Patrolman 5.56

 

The Bushmaster XM15 A3 M4 Patrolman 5.56 is a reliable and versatile AR-15 variant that offers solid performance and value for the price. Bushmaster has a reputation for producing reliable firearms, and the XM15 A3 M4 Patrolman upholds that reputation.

It has a traditional M4-style design with a 16-inch chrome-lined barrel and a standard M4-style collapsible stock. The overall build quality is commendable, and the rifle feels solid and well-balanced. The Bushmaster’s M4 Patrolman features a forged A4 flat top receiver constructed of 7075-T6 aluminum. It also has an A2 birdcage-style flash hider, Mil-Spec trigger and M4 style handguard with a detachable handle.

The XM15 A3 M4 Patrolman is often considered an affordable entry-level AR-15 option, making it attractive to budget-conscious buyers. It provides solid performance and reliability for its price range, offering good value for those looking to own an AR-15 without breaking the bank.

14. Stag Arms Stag-15 (New Jersey Compliant – Left Handed AR 15)

 

If you live in the state of New Jersey and looking for a NJ Compliant aR 15 then you should check out the Stag Arms Stag-15.  Although this is one in particular is an AR 15 for left handed shooters, you can find one for right handed shooters on the site.

The Stag Arms Stag -15 upper and lower receivers are forged from high-quality 7075-T6 aluminum, ensuring robustness while maintaining a lightweight profile.

The Stag-15 incorporates a carbine-length gas system, which promotes smooth and reliable cycling. It handled a variety of ammunition without any feeding or ejection issues, ensuring consistent performance on the range.

The rifle consistently delivered tight groupings during my range sessions, which can be attributed to its precise barrel and overall solid construction. Whether shooting at close or moderate distances, the Stag-15 demonstrated commendable accuracy.

The handguard provides sufficient space for adding accessories, such as optics, lights, or grips.

15. Heckler and Koch MR556A1 RIFLE

 

Last on our list is Rolls Royce of AR-15s.  Right out of the box, the Heckler and Koch MR556A1 exudes quality craftsmanship. The rifle features a sleek and robust design, with meticulous attention to detail evident in every aspect. The upper and lower receivers are made from high-quality materials, ensuring durability and a precise fit.

Utilizes a gas piston operating system, which enhances reliability and reduces fouling compared to direct impingement systems. This design feature contributes to the rifle’s exceptional reliability, ensuring smooth cycling even in adverse conditions. The rifle reliably fed, fired, and ejected rounds without any malfunctions or issues during my range sessions.

The recoil management of the MR556A1 is superb. The gas piston system, combined with H&K’s proprietary buffer system, effectively reduces recoil and muzzle rise, allowing for quick follow-up shots and improved control.

The rifle features a collapsible stock, allowing for adjustable length of pull to accommodate different shooters. The handguard provides ample space for adding accessories such as optics, lights, or grips, ensuring customization options to suit individual preferences.

Honorable Mention “Best” AR 15s

Here we feature some AR-15s based on different “Best” criteria

IWI ZION Z-15 – Best AR 15 for Under $1,000

 

Arguably one the finest examples of Israeli Weapon Industries’ (IWI) craft, this weapon sure does have some fight in it. Right out the gate, the ZION Z-15 certainly commands an aura of reliability and precision, purposed for someone who isn’t just after the basic bells and whistles of a firearm, but someone who wants a little more AR-15 for their buck.

Pros of the Zion Z-15

Now, across the web, you’ll notice a seemingly unanimous consensus commending the accuracy of this unit. Hold steady your breath and this weapon is as reliable as your grandfather’s old hunting tales. Constructed with a 16-in barrel, allowing for a swift bullet speed of around 3,000 feet per second. It’s capable of hitting a precise point target at ranges upwards of 500 yards.

The direct gas impingement operation of the Z-15 makes recoil a non-issue. It absorbs substantial energy, making it light on the shoulder and easy to maintain alignment through successive shots.  The cold hammer-forged barrel ensures high durability and minimizes wear due to frequent use.

It’s shrouded in black Cerakote finish making it resistant to corrosion and ensuring long-lasting aesthetic appeal.

Cons of the Zion Z-15

We found the milspec trigger a long-pull and somewhat heavy. A good and well-known upgrade for AR-15s is an improved trigger, a detail IWI seems to have overlooked on the ZION Z-15. Check out our article on the best AR triggers you might consider. 

The lack of a collapsible stock for more compact storage and transport may also be a mark down for some buyers. Make no mistake, this is a full-bodied AR, strong in stature, and nothing about it manages to hide that fact.

When searching for an AR 15 under $1,000 the ZION Z-15 offers an admirable blend of accuracy, durability, and minimal recoil. Adding an aftermarket AR trigger and upgrading the AR stock are the only suggestions we’d make.

Knights Armament SR15 – Best AR-15 for Hard Use

 

 

If you’re lookin’ for a reliable, hard-hitting AR 15 that you can beat the crap out of, you might consider the Knights Armament SR15. The Knights Armament Company, based in Florida, has been in the game of manufacturing firearms and accessories since the 1980s. A long-standing supplier for the military, they’ve built their reputation on crafting rugged and reliable weapons.

Right from the get-go, you notice the SR15 is a well put together piece of machinery. The upper and lower are forged from 7075-T6 aluminum, giving ’em a handy combo of strength and lightness. It’s got a 16-inch chrome lined, hammer forged barrel that can put bullets on target smoothly and consistently. The SR15 is known for delivering a real punch packin’ performance when it comes to accuracy. The 1:7 twist rate in the barrel ensures the rounds are well-stabilised, giving them accuracy at long ranges.

Pros of the Knights Armament SR15

You’ve got a rifle with an extended lifespan due to its chrome-lined barrel. You’re looking at an accuracy-driven firearm attributed to a well-leveled two-stage trigger. All while being decent weight, not too heavy so it won’t be knocking the wind out of you.

Cons of the Knights Armament SR15

The SR15 may require a bit of trial and error to find your perfect ammunition match. The process is needed for you to enjoy the full flavor of accuracy the SR15 brings to the table, but can be a tad frustrating.

Best AR-Pistol – CZ-USA CZ BREN 2 MS 5.56 AR PISTOL

 

 

When it comes to the best AR 15 Pistol the CZ-USA CZ BREN 2 MS is not some toy; it’s a piece of precision engineering. Hailing from the Czech Republic, this crossover beauty blends the robust reliability of a pistol with the vicious punch of an AR. And look, it’s not entirely perfect, but as a sidearm or a compact primary firearm for close-quarters engagements, it snarls and bites with the best of ’em.

This AR pistol is a visually striking weapon. Plus, it’s been modernized for versatility. From the polymer frame to the Picatinny rails and flip-up adjustable sights, the CZ BREN 2 MS has a sleek but tactical vibe that delivers on its promise of reliable function.  It features a cold hammer-forged barrel for surefire accuracy. The Bren also employs a gas piston system which translates to lesser recoil, cleaner shooting, and less fidgeting around with maintenance.

Pros of the CZ BREN 2 AR Pistol

Handling: The piston-driven system makes for a less bumpy ride and a more effortless operation.

Design: This pistol has plenty of Picatinny rails for all the trimmings you might want and a charging handle that doesn’t get in your way.

Reliability: Because of the improvements from its predecessor, the CZ 805 BREN, very few issues will be faced regarding malfunctions.

Cons of the CZ BREN 2 AR Pistol

Cost: Brace yourself, this fine piece is a budget-buster at around $1800.

Weight: When fully assembled, it weighs a significant 5.86 lbs, which is certainly not on the lighter side.

Trigger: A clean pull is something you won’t get with this one. It’s heavy, gritty, and leaves something to be desired.

Best AR-15 in 9mm – LEAD STAR ARMS BARRAGE

 

 

LEAD STAR ARMS is a well-respected vendor within the firearms community, known for producing top quality rifles. Their venture into pistol-caliber carbines has been eagerly anticipated, and the BARRAGE AR-9 is one hell of an introduction. The upper is crafted from 7075-T6 Billet aluminum.

Best AR-15 for Left Handed Shooters – STAG ARMS STAG-15L

 

This rifle was designed to offer southpaws the same level of comfort and convenience that right-handed users get from a standard AR-15.  Stag Arms has a reputation for constructing high-quality, dependable firearms, and the Stag-15L isn’t an exception. This rifle boasts a slew of features catering to left-handed shooters.

To start with, the Stag-15L sports a left-handed upper receiver. That means the ejection port and forward assist are positioned on the left side of the rifle. No more hot brass flying past your face, how’s that for comfort?

The Stag-15L also utilizes a mirror image of the standard AR-15 lower receiver. This modification reverses the position of the safety selector, placing it on the right side. In addition, the magazine release button has moved to the right side. So, left-handers can now change magazines using their dominant hand without adjusting their firing stance.

Stag-15L Pros

As mentioned, the Stag-15L is specifically designed to cater to left-handed shooters, offering complete mirrored controls. You get reversible safety selectors, ejection port, forward assist, and magazine release, resulting in more seamless operation.

Thanks to the 16-inch barrel, the rifle ensures better performance in tight quarters and minimizes fatigue during extended use.

The 5.56 NATO chamber, combined with a 1:7 twist rate, provides the capability to handle a wide array of ammunitions.

Stag-15L Cons

Some left-handed shooters may prefer the traditional right-hand set-up for strategic advantages and compatible parts. The Stag-15L does not offer a hybrid setup for such preferences.

In the world of AR-15s, the Stag Arms Stag-15L stands out, especially for southpaws. It’s designed to give left-handers the same access right-handers have had for years, without compromising on reliability, durability, and, most importantly, performance.

DPMS PANTHER ARMS ORACLE AR-15 – (Best AR-15 for Easy to Take Down & DIY Customization)

 

The DPMS Panther Arms Oracle AR-15 is a diamond in the rough for folks who like to mix things up.

First off, one big charm of Oracle AR-15 is its modular design. To a gun enthusiast, modularity is like being a kid on Christmas morning. With the Oracle, you can add, remove, or modify components as per your preference. Want to slap on a laser sight or flashlight? Easy. Thinking about different grips or stock? Go ahead! The Oracle makes all these possible in a snap. You’re not stuck with what you initially buy, but instead you have a foundation to build and customize the exact firearm you wish you had. Now that’s what I call freedom.

However, if you’re a newcomer, don’t worry your pretty little head about it being perfect right outta the gate. The Oracle works great as a basic rifle, too—it’s darn simple to handle and it sure shoots smooth. But as you grow as a shooter, you’ll want your rifle to grow with you, and that’s where the Oracle shines.

The affordability of the Oracle is an undeniable pull factor. Sure, top-tier rifles are good, but not everyone has that kind of coin to drop. The Oracle combines quality with value—it won’t leave your pockets empty. This means you’ll have more left for ammunition, range fees, or even AR-15 customization that you’ve been longing for.

PSA Palmetto State Armory AR-15 PISTOL 10.5″ CARBINE – (Best AR-15 with a Short Barrel)

 

The PSA AR-15 Pistol is a high-capacity firearm mirroring the power and efficiency of your standard AR-15 rifle, but comes in a smaller package. This bad boy’s most defining characteristic is its barrel length of 10.5″ making it easy for rapid deployment in tight spaces, a definite tactical advantage in personal defense situations.

When it comes to performance, the AR-15 pistol doesn’t fall far from the tree. It is highly accurate, courtesy of its 1:7 twist rate and carbine-length gas system.

4. Detachable Rear Sight: The detachable Magpul MBUS rear sight allows you to easily add your preferred optics.

PSA Palmetto State Armory AR-15 PISTOL 10.5″ CARBINE – Cons

1. Not Ideal for Long Range: Shorter barrel length makes it less than ideal for long-distance shots.

2. Requires Proper Handling: As a firearm, it can be a bit “jumpy” because of its short barrel, requiring firm handling.

3. Limited Customization: The compact design can limit customization options compared to full-size rifles.

What is the Difference Between an AR-15 Pistol and an SBR (Short Barrel Rifle)?

Now to consider the difference between the AR-15 Pistol and a SBR. In short, here’s the deal: the AR-15 Pistol is technically not a rifle. According to the law, it’s classified as a pistol due to its lack of a traditional stock. Instead, some have a stabilizing brace, most don’t. What it means practically is that you avoid extra legal paperwork hassles which an SBR requires.

A SBR, on the other hand, is technically a rifle with a barrel of less than 16 inches or an overall length less than 26 inches. It has a traditional rifle stock. However, the SBR must be registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) and requires payment of a $200 tax stamp, a process that comes with a hefty wait time.  Adding a stock to an AR pistol can get you into hot water if not legally registered. 

In the end, though the anatomy of these two types of firearms is similar, the designation between the AR-15 Pistol and the SBR boils down to their intended function, legal classification, and the presence of a rifle stock or pistol stabilizing brace. So, knowing your intended usages and familiarizing yourself with your state laws is crucial before diving into a purchase of either weapon.

If you’re planning to plunk down just a few hundred bucks for an AR-15, it ain’t gonna cut it for reliability, performance, and longevity. But don’t fret, this ain’t no millionaires’ club. You don’t have to break the bank to get yourself a decent AR-15.

Smith & Wesson M&P15 Sport II (Best AR-15 for Beginners)

From my experience, and mind you, I’ve seen quite a few rifles in my time; The best AR-15 on a budget is the “Smith & Wesson M&P15 Sport II”. Smith & Wesson ain’t some newbie, they’re tried-and-true in the firearms world. The Sport II is dang reliable and durable, making it a great choice for your first AR-15 or if you’re just looking for a solid backup.

 

Sporting a 16” barrel, it delivers a dependable accuracy. It comes equipped with a 30-round mag which is quite standard for an AR-15 rifle. Also, it has an adjustable sight and is even designed with a dust cover and forward assist, features usually found only in higher priced rifles. 

Ruger AR-556

Now, if you wanna fork over a few more dollars but still stay within a reasonable budget, consider the “Ruger AR-556”. This lil’ number is another great AR-15 that ain’t gonna eat into your savings. It comes with a 16.1-inch barrel and offers exceptional performance with the added bonus of a gas block allowing adjustment according to the load you’re using.

In essence, the best AR-15 for your hard-earned cash ain’t all about the badge or the price tag. It’s about how well it fits your needs, your budget, and your hand. It’s about how well you maintain it, the accessories you choose, and most importantly, how well you can handle it. Choose wisely, shoot responsibly.

Why the AR-15 is Popular?

The AR-15 rifle is popular because of its versatility, accuracy, and ease of use. It is lightweight and has low recoil, making it a great choice for target shooting, hunting, and even home defense.

In addition, the modular design of the AR-15 allows for customization and a variety of accessories. The rifle is also relatively affordable and widely available.

There are many reasons why the AR-15 has remained the most popular of all civilian rifles. Here is a list of the top five reasons why I think they are so popular:

Are AR-15’s used by the U.S. Military?

Does the military use the AR-15? Technically, no they don’t. The US military uses the M4 whereas civilians are legally allowed to only use the semi-auto AR-15. This differs from the automatic/select fire capabilities of the military variety.

What does “AR” in an AR-15 stand for?

The AR in AR-15 stands for ArmaLite Rifle. Contrary to popular belief, AR does not stand for “Assault Rifle”. Armalite was the original manufacturer of the weapon. ArmaLite would go on to sell the design of the rifle to Colt in 1959. Today the term AR-15 is used to describe rifles of similar configurations from a myriad of different manufacturers.

What does Semi-Auto mean?

Semi-auto means with each pull of the gun’s trigger, only a single round is fired. This makes the AR-15 significantly slower to shoot compared to the military version of the rifle, the M4, which fires has a 3-shot burst option (three rounds are fired with a single pull of the trigger) and a full auto option (the gun will empty the entire mag if the user doesn’t let go of the trigger).

Personally, I prefer firing any gun in semi-auto. When doing target practice, I get to focus on each shot and don’t end up wasting bullets.

In real-life home defense scenarios where most of us only have to deal with one or two people, the ballistic performance of the 5.56×45mm caliber should be plenty powerful — a single shot should be enough to repel, maim or even kill a bad guy if needed.

You can pick up practically any gun-related magazine and you will see ad after ad of aftermarket AR-15 accessories and parts.

To really put this into perspective, Brownell’s has a catalog of AR-15 parts that rivals the Yellow Pages in size, and Brownell’s is just one of many. That’s how readily available AR-15 aftermarket parts and accessories are.

AR-15 Intended Purposes – Why Do You Need an AR-15?

You hear all the time, mostly in social media, “why do you need an AR-15?”. Here are 5 reasons you need or can use an AR-15.

Hunting:

You wouldn’t think of an AR-15 as a first choice hunting rifle, but you’d be wrong. Depending on your choice of caliber, an AR-15 makes for a handy tool out in the woods. With some states lifting restrictions on the use of semi-automatic rifles for hunting, you can now use your AR-15 platform for bagging deer, hog, or small game. Just ensure you’re using a caliber appropriate for your intended game.  Check out our complete article on the best AR-15 for deer hunting.

Competition Shooting:

If you’ve got the competitive spirit, consider entering one of many competitions designed for the AR-15. The rifle’s stability and accuracy make it a top choice for target shooting events. Speed shooting, precision shooting, or three-gun competitions — AR-15’s can handle them all. Customization options allow you to adjust your rifle to precisely fit your competition needs.

Recreational Shooting:

Maybe you’re into shooting for the sheer enjoyment of it — the focus, the skill, the satisfaction of hitting that bull’s eye. With an AR-15, a day at the range sure livens up. As we’ve said, the recoil is manageable, meaning you won’t wear yourself out shooting repeatedly. Plus, the AR-15’s modularity allows you to mix and match equipment to enhance your shooting fun.

Training and Education:

Never held a gun before, or looking to teach someone about firearms? The AR-15 serves as a solid choice for training new shooters. It’s straightforward to use and, thanks to reduced recoil, beginners find it easier to handle, keeping their focus on learning techniques and safety procedures. Experienced shooters can hone their marksmanship skills or try out new shooting styles.

Home Defense:

It’s one of the chief reasons you picked up a gun in the first place, right? To protect the house and family. The AR-15 comes in handy for this job. Its light weight and manageable recoil make it easy for folks of all sizes and strengths to operate. It also has a large magazine capacity, increasing your chances of stopping an intruder with fewer reloads. Plus, with the right ammunition, an AR-15 doesn’t over penetrate walls — keeping your loved ones safe.

Is the AR-15 the Best Home Defense Weapon?

The AR-15 can be considered one of the best home defense weapons for several reasons. The most notable reason is the stopping power of the .223 cartridge the majority of ARs are chambered for.

Additional AR-15 as a Home Defense Weapon Pros

The AR is also highly customizable which allows you to add close quarters optics, lights and grips. Also, the additional ammo capacity of an AR-15 versus a shotgun or a handgun, gives the ability to handle multiple threats in a home invasion.

Finally, due to the longer barrel, ergonomic design and minimal recoil, the accuracy of an AR-15 can be beneficial for engaging targets precisely and effectively. However, there are cons to using an AR-15 for home defense.

Why Shouldn’t You Use an AR-15 for Home Defense?

The number one reason not to use an AR-15 for home defense is overpenetration. AR-15 rounds have a high velocity rate. This means they can penetrate through walls and other barriers easier than a handgun or shotgun. This increases the risk of unintended damage to people or property in adjacent rooms or even nearby residences.

Size and maneuverability could also be a concern when using an AR as a home defense weapon.  The AR-15 is longer and bulkier than handguns or shotguns, which can be a disadvantage in close quarters. It may be more challenging to navigate narrow hallways or corners, potentially limiting maneuverability and making it harder to wield in tight spaces.

AR 15 – Shootability

The AR-15 as a shooting platform has relatively more manageable recoil compared to other rifle platforms, particularly so when chambered in its intended 5.56x45mm round. It also offers relatively better ergonomics than other popular rifles, such as the venerable AK-47.

It is a precision-built tool specially designed for accuracy with some models tricked out with easy-grip hand guards, scope mounts, and more. This is why many rifle purists and even hunters swear by the AR-15.

And this brings us to number four our my list of reasons why the AR-15 is incredibly popular.

AR 15 – Modular Design

The AR-15 is primarily comprised of two segments—the lower receiver and the upper receiver, each of which can be easily swapped out in as fast as a few seconds, provided the user has put enough time to practice field stripping and reassembly.

I’ve seen a few people assemble an AR real fast even when blindfolded.

This modularity makes the AR-15 stand out as a weapon platform: it’s easy to clean, easy to maintain, easy to field strip, and easy to reassemble.

This also makes it versatile because in a pinch, with the right parts and accessories, it can be configured as a DMR (Designated Marksman’s Rifle) high-precision rifle, a hunting rifle (using bigger caliber barrels and ammo), or by default, as a CQB (Close Quarters Combat) carbine by simply switching out the upper receivers and barrels.

AR 15 Versatility

What’s more, the upper receiver and barrel can be swapped out for a ton of different calibers like the significantly weak but plentiful .22LR or the monstrosity that is the .50 Beowulf.

If you’ve never heard of the .50 Beowulf, it’s essentially a 50-caliber round that has the same ballistic performance as that of the most powerful production revolver caliber, the .500 S&W Magnum, designed primarily for big game hunting.

The only difference between the two is firing the .50 Beowulf in a rifle platform is significantly more manageable than firing the .500 S&W Magnum in the wrist-breaking S&W 500 X-frame revolver — that, and you get more rounds in the mag with the AR-15 compared to only five shots in the X-frame revolver’s cylinder.

As mentioned earlier, there is no end to the aftermarket products with which the AR-15 can be customized to suit anyone’s specific preferences and needs. The sky’s the limit when personalizing the look, feel, and performance of your rifle, provided you have the money to burn.

People make fun of some AR-15 enthusiasts who like to pimp their gun, overly customizing it to impractical tacticool levels, but I say to each his own. It’s your hard-earned dollar, don’t let anyone tell you how you should be spending it.

Banning of AR-15s and Assault Weapons

If someone tells you that you can’t have something, you end up wanting it that much more.

That was the case with the AR-15 back when then-POTUS Bill Clinton signed into Office the 1994 Assault Weapons Ban. This ban prohibited the manufacture and sale of certain semi-automatic firearms with specific features, such as folding stocks, bayonet mounts, and high-capacity magazines. However, the ban had a sunset provision and expired in 2004.

 

After the expiration of the federal AWB, several states, including California, New York, and Connecticut, implemented their own assault weapons bans.

What States Have Banned AR-15s?

States that have banned AR-15s (Assault Weapons) when this article was last updated include: California, New York, Connecticut and Maryland.  State-level assault weapon bans vary in terms of their specific provisions and restrictions. Here is a summary of some states that have implemented assault weapon bans and their key details:

California Assault Weapon Ban:

California has one of the strictest assault weapon bans in the United States. The state’s ban includes a list of specific firearms, as well as a “generic” definition that covers certain features, such as pistol grips, thumbhole stocks, and flash suppressors. The ban prohibits the manufacture, sale, transfer, and possession of these weapons, unless they were owned prior to the ban and registered with the state.

New York Assault Weapon Ban:

New York implemented the New York Secure Ammunition and Firearms Enforcement Act (NY SAFE Act) in 2013, which includes an assault weapon ban. The law defines assault weapons based on a list of specific firearms and also includes certain features, such as folding or telescoping stocks, pistol grips, and threaded barrels. The NY SAFE Act prohibits the sale, possession, and transfer of these weapons, with exceptions for those owned prior to the ban.

Connecticut Assault Weapon Ban:

In response to the Sandy Hook Elementary School shooting, Connecticut enacted the Assault Weapons Ban in 2013. The law classifies assault weapons based on a specific list of firearms, as well as features such as folding stocks, bayonet mounts, and grenade launchers. It restricts the sale, possession, and transfer of these weapons, with certain exceptions for those owned prior to the ban.

Maryland Assault Weapon Ban:

Maryland implemented the Firearms Safety Act of 2013, which includes an assault weapons ban. The law classifies assault weapons based on a list of specific firearms and also includes specific features such as folding stocks, flash suppressors, and grenade launchers. It prohibits the sale, possession, and transfer of these weapons, with exceptions for those owned prior to the ban.

It’s important to note that the details of state-level assault weapon bans can change over time, and there may be additional states with their own versions of such legislation. It’s advisable to refer to the specific laws and regulations of each state for the most up-to-date and accurate information.

History of the AR-15

The first AR-15 was manufactured in 1958 by Eugene Stoner for ArmaLite (which is why it’s a no-brainer that ArmaLite should land on this list). It was a lightweight 5.56x45mm variation on the 7.62x51mm AR-10.

The lighter bullets made it so that infantrymen could carry more rounds with ease.

Most people associate the AR-15 with the Colt name because Armalite sold the rights to Colt in 1959. But think about the name AR-15 — what does the AR stand for?

If no one ever told you, the AR is short for Armalite (not “Assault Rifle” as so many folks in the media would lead you to believe.)

Over time, Colt tweaked the design and came out with the M16, a select-fire (auto) design with a twenty-inch barrel.

In the ’90s, the M4 was introduced featuring a 14.5-inch barrel and a carbine gas system. Carbine is a word that basically serves as a shorthand for “shorter barrel.”

The AR-15 is the civilian semi-auto version of the fully-automatic M4. To reiterate what was said earlier about semi-autos, one pull of the trigger equals one shot.

Since Colt owns the rights to the AR-15 name most manufacturers use slight variations on the name such as ARX, A4, or, more cleverly, “PredatAR.”

Now, to answer a pressing question:

---

Should I Buy or Build an AR-15?

For those of you who are purchasing your first-ever AR-15, I would highly advise you to buy a complete AR-15 from a trusted manufacturer from our list. At the very least, you should buy a total upper and possibly try to customize your own lower.

This will prevent a lot of inconveniences because you will have a full warranty on your rifle. Also, when you’re just getting started, you might not know exactly what you want or need so it’s best to go with a standard configuration.

Factory-grade rifles are generally pretty affordable which means that you won’t have to spend much more than you would if you were building your own. Besides, beginners aren’t exactly adept at assembling their own firearm so this takes the headache out of the whole process.

Another factor here is resale value. As I learned the hard way when I posted an ad in the past, self-built rifles are practically worth nothing when compared to branded pre-built firearms.

Building Your Own AR 15

On the flip side, many people enjoy the sense of pride they get from building their own. Designing your very own “Frankengun” can be a satisfying and fun experience, but I recommend getting your hands on a standard AR before attempting to go the DIY route.

I think you’ll have an easier time building one after you’ve spent some time with a factory gun.

For those who have graduated from the factory-built AR-15 and want to build your own AR-15 lower receiver, there are several resources out there that will walk you through the process.

I recommend this helpful and informative YouTube video, which covers the process from start to finish.

AR 15 – Barrels

This is another important area that needs to be covered, especially for first-time shooters. We’ll begin by breaking down the AR-15 system by talking about the multiple characteristics of barrels.

This can be boring or fun depending on your level of familiarity with the platform.

Barrel Chamber

The chamber is that part of the barrel where the cartridge resides before it is fired. This, and the barrel itself, determine what kind of ammo your rifle can shoot.

For beginners, you’ll want to focus only on the most common loads— the .223 Remington and the 5.56X45 mm. As mentioned earlier, there are lots of rifle calibers available for the AR-15, from the lowly .22LR to the powerful .50 Beowulf, but the .223 Remington and the 5.56X45 mm are the two best offerings for novices.

The 5.56mm is the most popular choice for home defense and fun plinking sessions. It is readily available so ammo is cheap.

Now, this might seem like a no-brainer but when it comes to guns, safety should always be a top priority. With that in mind, here are some guidelines first-time AR-15 owners have to remember:

• With a .223 barrel, you can only fire .223 rounds.
• Hybrid chambers like Wylde are implemented for specific reasons but can fire a .223 or a 5.56.
• The 5.56 barrel, on the other hand, can fire both 5.56mm AND .223 Remington
• Always clean and lube before shooting, especially if your rifle is new.
• Always protect your eyes and ears with goggles and ear plugs
• Consider taking shooting lessons/classes before purchasing an AR-15.

Barrel Length

The minimum barrel length, according to Federal law, is sixteen inches. If an additional device is used, such as a muzzle brake or flash hider, it has to be permanently attached if it will be included in the rifle’s length.

For instance, gun owners can have a 14.5-inch barrel and weld a muzzle device that’s 1.5-inch long in order for the gun to be compliant with Federal requirements.

However, it is important to note that some states and municipalities have their own laws governing firearms and their accessories, so be sure to familiarize yourself with the rules and regulations in your area.

Due to these restrictions, we strongly advise first-time shooters to purchase at least a sixteen-inch barrel so that they can swap out muzzle devices at will. There are three main lengths that are popular: 16”, 18”, and 20”.

One thing that beginners should be aware of is the length of an AR-15’s barrel doesn’t necessarily equate to accuracy. Anyone who knows what they’re doing can achieve plenty of accuracy with a sixteen-inch barrel because it is stiffer and thus less affected by barrel whip.

On the other hand, longer barrels can provide higher velocities as there is more space for the powder to burn and more room for the bullet to accelerate.

Faster Bullets Mean

When bullets are able to move faster, there is far less time for environmental factors to affect the bullet’s trajectory (e.g. wind and gravity), meaning that each shot will be relatively more powerful and a bit more accurate over longer distances.

On average, sixteen-inch barrels are able to reach a target from four hundred yards away. That being said, the traditional fifty-five-grain load grows more imprecise after three hundred yards, so fire carefully.

If you’re looking to fire at a longer range, you would fare better with a heavier, longer load like a sixty-two-grain, seventy-seven, or eighty-grain bullet.

When I’m considering a weapon of any kind, I always think about portability. Shorter barrels generally weigh less and are easier to handle.

AR 15 Barrel Material

When you first get into guns, it can be overwhelming. There are so many numbers and so much technical jargon that it might seem scary or confusing.

This is especially true of barrel material which is why I’ve tried my best to simplify it for the newbies out there who are just learning about this stuff.

• 4140: This consists of steel with ten percent less carbon compared to its predecessor, 4150 steel.
• 4150: Steel used in mil-spec barrels.
• Stainless Steel: This one is more accurate but isn’t as durable as 4150 or 4140 steel.
• Chrome Molybdenum Vanadium, Chrome Moly, or CMV: Basically identical to 4140

There are slight differences between the last one and 4140. Chrome Molybdenum Vanadium steel alloy contains a range of elements from chromium and nickel to molybdenum and so forth. It is renowned for its strength and hardness.

“Chrome Moly” or Chromium-molybdenum steel, is a range of low alloy steels that are of high tensile strength and aren’t as lightweight as counterparts like aluminum.

4140 alloy steel is a combination of chromium, molybdenum, and manganese and has high fatigue strength, impact, and abrasion.

Both are high tensile strength steels which makes them great for guns as well as bicycles and the like.

The average shooter should probably just stick with 4140 or CMV because there’s really no benefit to using 4150 unless you’re dealing with a fully-automatic piece. Besides, you’ll save money as 4150 costs more.

Barrel Lining

There are three basic options on the market when it comes to the inside of your AR-15 barrel. They are as follows:

• Ferritic Nitrocarburizing (FNC): Otherwise referred to as Melonite, Tennifer or Nitride, FNC treats the surface of the barrel instead of just coating. This can result to increased accuracy.
• Chrome Lined: A popular form of barrel lining. It is a coating that makes for better barrel longevity, but that longevity comes at a price — accuracy might suffer. If either end of the barrel has a gray ring around it, it’s chrome lined.
• None: Some barrels have absolutely no coating whatsoever.

Many environmental factors such as heat, moisture and more can affect your exact round count, but you can count on approximately ten to twenty thousand rounds before you need to re-barrel.

If you’re still with me, let’s move on to testing, another important area to be aware of.

AR 15 Barrel Testing

As I said before, there is a lot of technical mumbo jumbo that comes with owning guns. Some acronyms that manufacturers like to throw at you include the following:

• MP: Magnetic Particle tested. This just means that it’s essentially subjected to X-Rays to check that the gun doesn’t have any voids, cracks or other imperfections.
• HP: High Pressure tested. This is a method by which manufacturers ensure the integrity of anything from primers and projectile seating depth to chamber parameters and neck tension.

Of course, some AR-15s have not been tested at all, so buyer beware! If a gun’s packaging or advertising specifically says it hasn’t been tested or doesn’t mention testing, you’re buying it at your own risk.

Barrel Forging

• Cold, Hammer, Forged (CHF): This is a process that results in a more durable barrel. Repeated blows by a series of hammers align the grain within the metal, causing more strength and rigidity.
• Barrel, Forged, Hammer (BFH): Essentially the same as CHF, BFH is where a mandrel (carbide tube) is inserted into the barrel, rotated and pushed forward to create precise rifling.

With these options, you lose some accuracy but they make up for that with increased durability.

Barrel Contours

This refers to the thickness and overall shape of your barrel. Fortunately, there are several options available.

They include:

• CAR (Colt Automatic Rifle): This one used to be the name of a certain group of AR-15s and M-16s back in the 1970s, but today it is a name for carbine-length rifles.
• Light: This one is just what it sounds like, it’s lighter than others but it’s vulnerable to the heat associated with rapid firing. This one’s .625-in in diameter.
• Heavy (Bull): This one is heavier and stiffer, but it’s also far more accurate. I like this one a lot because it can handle more heat than others before it starts to be affected. It’s typically implemented for precision builds. Bulls are .936” in diameter.
• Medium (M4): The M4 contour possesses a cutout for grenade launchers which is what makes it ideal for military purposes. It’s got terrific balance and is .750” in diameter.

In my opinion, the average plinker doesn’t require anything more advanced than light or medium barrel.

Barrel Feed Ramp

This is a vital part of the AR-15’s upper receiver, therefore you want it to properly match the barrel of your rifle.

It is still debatable as to whether or not the barrel’s feed ramp affects reliability, but at the very least, it’s important to match the ramp with the upper receiver. Usually, if you buy factory-made rifles this won’t be an issue, but you should still check to confirm it.

Barrel Twist and Bullet Grain Ratio

When it comes to the AR-15, two critical factors can significantly impact its overall performance – the barrel twist and bullet grain ratio. Understanding their importance can help you make the right choice when buying an AR-15 or when selecting ammunition for your rifle.

Let’s start with the barrel twist. The term refers to the rate at which the rifling inside the barrel rotates the bullet as it’s fired. This spinning motion stabilizes the bullet in flight, improving its accuracy over long distances.

The barrel twist rate is expressed as a ratio, such as 1:7, 1:8, or 1:9. The first number refers to one complete rotation, and the second number is the length in inches that rotation takes. So, in a 1:7 twist ratio, the bullet makes one full rotation for every seven inches of barrel it travels down.

What type of barrel twist should I look for in an AR-15?

Choosing the right barrel twist for your AR-15 depends on the weight of the bullets you plan on firing, which brings us to bullet grain ratio.

The weight of a bullet is measured in grains, and this metric plays a crucial role in the AR-15’s overall performance. Heavier bullets, usually those over 62 grains, work better with faster barrel twist rates like 1:7 or 1:8. Lighter bullets, those under 55 grains, tend to fare better with slower rates like 1:9.

A bullet that’s too lightweight for a rapid twist rate might over-stabilize, and can even come apart mid-flight. Equally, too heavy a bullet with a slow twist rate may under-stabilize and lose accuracy over distance.

In essence, understanding how barrel twist and bullet grain ratios work is vital in optimizing the performance of your AR-15.

Here is a great barrel twist and bullet grain ratio to help you make sure you have the right combination.

AR-15 Gas Systems

Now that you know the basics of the AR-15, we’ll get into more complicated stuff.

There are two primary types of gas systems for the AR-15. They are DI and Piston. DI stands for Direct Impingement. DI is the original design whereas the Piston only became popular in recent years.

What is the difference between a DI gas system and a piston gas system?

The AR-15 operates by transmitting hot gas behind the bullet into the gas tube at which point it the gas tube uses the gas to either move a piston or deliver the gas directly back (direct impingement).

No matter how the force is applied, it makes the bolt unlock, move back, eject the spent casing and pushes a new cartridge into the chamber.

By and large, most AR-15s are DI instead of Piston. Like most things, there are pros and cons to each.

Pros of Piston Gas System

• Typically more reliable in poor weather conditions (dust, water, moisture, heat, et al.)
• Relatively cleaner as dirty gas is vented out

Cons of Piston Gas System

• More expensive than DI
• Heavier with more weight in front
• Harder to find proprietary parts from manufacturers
• Less accurate than DI

Unless you’re in an Arnold Schwartzenegger movie where you have to fire your weapon coming out of water or you live in a desert somewhere, a DI system will be perfectly adequate for most purposes.

Assuming you properly maintain your AR-15, a DI model will be a dependable weapon.

DI Gas System Lengths

Gas system length is the distance to the gas hole. The gas hole refers to the triangular front site base (FSB) that sits on top of the barrel.

Although there is the rare “Dissipator” model that has a sixteen-inch barrel, the rifle-length gas system is normally used for an eighteen-inch barrel.

The average choice for sixteen-inch barrels is a carbine or midlength gas system.

Personally, I favor the midlength system because I think it’s advantageous because it enables the user to have a longer sight radius when you’re using a front sight base. You also get more rail space because the handguard extends from the upper receiver to that front sight base.

AR 15 Gas Blocks

We’ve mostly been talking about the FSB (Front Sight Base) style gas block here where the front sight is combined with the gas block and there’s a reason for that.

I always recommend this style to first-time shooters because it’s easier to have a front sight and it’s affordable to use a non-free-floating barrel.

Another good thing about this style is that it can be converted by grinding down the front sight base to allow for a free-floating barrel.

---

AR 15 Handguards

Front sight blocks generally use non-free-floating handguards. So the two-piece handguard touches the barrel at the front sight base which, unfortunately, can add a bit of inconsistency when it comes to force. Consequently, your shooting accuracy can be affected.

Nevertheless, if you are a non-competitive shooter, the non-free-floater will be accurate enough.

While there are some aluminum models, most are made from polymer and are cheaper and just as good at more affordable price points.

Magpul MOE handguards are our go-to handguards because they enable the shooter to attach Picatinny rails on slots which allow you to add accessories. Picatinny rails are a tad on the heavy side, but if you like to attach accessories, this is the way to go.

How the BCG (Bolt Carrier Group) Works

Alright, let’s cut to the chase and pull back the curtain on understanding how your firearm’s bolt carrier group (BCG) works.  The bolt carrier group is like the heart of your AR-15, it’s responsible for maintaining the rhythm, the ebb, and flow of operations. 

The bolt, the cam pin, and the firing pin, are the holy trinity of your BCG — everything revolves around these. The bolt’s where the magic happens — it houses the bullet, engaging and disengaging from your firearm’s barrel extension. Now, crack open that bolt, and you’ve got another mini puzzle of parts like extractor and the ejector.

Parts of the BCG

These small yet mighty parts may seem insignificant when you hold them in your hand, but they hold the power to transform your shooting experience. They are responsible for kicking out the spent casing after you fire and ensuring that your firearm reloads properly. Then, there’s your gas key and carrier, which plays a key role in the movement of the BCG within the firearm, essentially converting your gas operated system into a semi-automatic system.

The cam pin’s role is simple in theory, but crucial in execution. When you fire, the high-pressure gas propels it backward, causing the cam pin to rotate and unlock the bolt. Meanwhile, the firing pin is hitting the primer on the round, igniting the powder and sending the bullet out of the barrel.

It’s an orchestra of actions, each part flawlessly playing its role.  It retracts when you pull the charging handle back. When you let go of the handle, the bolt carrier group moves forward, strips a round from the mag, and releases a round into the chamber.  It’s no exaggeration to say the stakes are high as a slight glitch can quickly bring everything to a screeching halt. It’s awe-inspiring, seeing this industrial symphony in action — the sheer precision and scientific genius involved.

Semi-Auto vs Full-Auto BCG (Bolt Carrier Group)

Now, you might have hit a snag deciding on whether a semi-auto or a full-auto BCG is the right one for your AR-15. Let’s dive into what separates these two.

Size matters in the world of BCGs, and the full-auto version comes out as the heavyweight champion. It sports more metal at the rear end, which equates to increased weight overall. The reason for this additional heft is all about durability and reliability. Initially crafted for the fully automatic M16, the full-auto BCG can handle the higher rate of fire and heat generated by a fully-auto rifle, hence the additional metal.

Now, don’t get it twisted; the semi-auto variant is no slouch. It carries the same design as the full-auto, but it’s missing a chunk of metal on the underside of the carrier. The semi-auto BCG was built for lighter, more consistent use typical of civilian shooting.

Why would I consider the full-auto if I’m planning to shoot semi-auto?

So, you might be wondering, “Why would I consider the full-auto if I’m planning to shoot semi-auto? Isn’t that overkill?” I get you. Technically, the semi-auto BCG will run just fine in your AR-15. But, this isn’t just about need; it’s about longevity, reliability, and occasionally about legalities.

The extra weight on the full-auto BCG can help your AR-15 run more smoothly, due to the increased mass moving inside the gun during cycling. More mass equals less felt recoil, and that’s something any shooter can appreciate.

But, it doesn’t stop there. That extra chunk of metal on the full-auto BCG also tends to improve its lifespan. It offers more durability, and since the AR-15 design is quite ‘over-gassed,’ you can bet on your rifle cycling harder and faster than intended. Having a full-auto BCG can take the brute of this over-gassing with more grace, ultimately extending the life of your rifle.

Finally, as surprising as it may seem, full-auto BCGs are also more common on the market. Part of this is because of the military’s surplus, leading manufacturers to follow suit with their own production. As a result, it’s not only easier for you to source full-auto BCGs, but often also cheaper.

Is it illegal to have a full-auto BCG?

Now, before we wrap this up, let’s talk about the elephant in the room – legality. If you’re worried that simply owning a full-auto BCG would land you in hot water with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), you can breathe easy. The legalities of BCGs depend on whether your firearm can shoot fully automatically, not whether it has the potential to.

Now, onto the coatings. Here we’ve nailed down four of the most common ones you’ll be coming across: Phosphate, Black Nitride, Nickel Boron, and Titanium Nitride.

Phosphate Bolt Carrier Group Coating

The good old phosphate coating. Rugged and tried-and-true, it’s been the standard for mil-spec rifles for ages. It does one hell of a job withstanding heat and reducing friction, keeping your BCG running smooth. However, it’s a bit of a dirt magnet, meaning cleaning your BCG is gonna be a downright chore. Plus, extra lubrication will be on your list.

Black Nitride Bolt Carrier Group Coating

Lately, Black Nitride’s been edging into phosphate’s territory. Tough as nails yet smoother than phosphate, it avoids much of the dirt-catching troubles of its predecessor, making your cleaning just that little bit more bearable. Durability is not its weak point either. You can expect that Black Nitride BCG to be dealing a deadly lead shower for years.

Nickel Boron Bolt Carrier Group Coating

Got a few extra bucks to spare? Then Nickel Boron might catch your eye. The step-up in slickness lets your BCG slide right into action, no extra lube needed. And that shiny silver finish makes identification of carbon build-ups easier than pie, meaning clean-up is a breeze. Heftier price tag? Sure. But for the reduced maintenance, it might just be money well spent.

Titanium Nitride Bolt Carrier Group Coating

Lastly, we’ve got the king of the hill: Titanium Nitride. It’s slick, it’s durable, and with its gold finish, it looks like something right out of a sci-fi flick. It’s got all the benefits of the Nickel Boron, but it’s harder and even smoother. Most importantly, it’ll last through whatever you can throw at it. Of course, it comes with a price to match its performance.

The Impact of Bolt Carrier Coating on AR-15 Performance

Each of these coatings brings its own to the table, impacting your AR-15’s performance in different ways. 

Phosphate cuts down on heat and friction but demands good upkeep and a generous hand with the lube. Black Nitride, on the other hand, brings the same heat resistance to the table, with a bit less fuss on the cleaning and lubrication front.

Nickel Boron steps up the game with improved slickness and easier maintenance. The need for lubrication lessens, which means you’re running smoother for longer, especially when operating in arid or dusty conditions. The ease of cleaning also promotes longevity, which can result in a more reliable AR-15 over the long haul.

And Titanium Nitride? It’s the cream of the crop. The top-tier slickness means less grime, less friction, less heat, and thus, less wear and tear. Your AR-15 is gonna thank you for it, with every smoothly operating trigger pull.

When choosing the BCG coating, it all boils down to what you’re gonna get out of it. If you’re willing to put a bit of grit in for upkeep, Phosphate or Black Nitride might be your best pals. Else, if you’re a bit more free-handed with the greenbacks for lesser maintenance, you might

The Best AR-15 Manufacturer List

There are a number of other factors that you’ll want to consider when selecting your AR-15.

They include build (precision build or 18” barrel vs pistol build or short-barreled rifle), optics, trigger (single stage vs two stage trigger), rifle type (chambered in), but for the sake of brevity, let’s get right down to it.

Below is a full list of all the top AR-15 manufacturers around followed by my personal favorites.

These are the manufacturers that seem to be reputable rifle vendors who don’t cut corners and commit to providing quality materials. Either that or they’ve just got a crazy marketing budget that makes them look, boss.

Top Tier AR 15 Manufacturers

As of the publishing of this article, we vouch for the following eight companies as the absolute best manufacturers of AR15 rifles:

Bravo Company Manufacturing
Colt's Manufacturing Company
Daniel Defense
LaRue Tactical
LMT Defense
Noveske Rifleworks

The companies listed above are believed to be the greatest sources for service-grade AR-15s.

Mid-Tier AR 15 Manufacturers

Anderson Manufacturing

Spike's Tactical

These are some companies with good guns that are fine for training/range-plinking purposes. I suggest you run at least 1,000 rounds through one of these rifles before you trust any of them with your life.

You want to know that your AR works before affording it the title of great home defense weapon.

Budget AR-15 Manufacturers

Don’t be thrown by the title, these are perfectly adequate manufacturers with perfectly good guns. They are inexpensive and may be the right choice for starter rifles.

AR-15 Price Points

When it comes to the top tier, you should be prepared to spend no less than $1,000. On the other hand, most mid-tier manufacturers’ rifles start at $500.

$1,000 might sound steep, but keep in mind that you’re paying for quality, name, and the research and development that goes into the same.
