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

 

 

 

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.

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

 

 

 

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.

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

 

 

 

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. 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.

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.

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.

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.

Direct Impingement vs Piston

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

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

Cons of Piston

• 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.

BCG (Bolt Carrier Group)

The BCG is basically the engine that runs the AR-15. 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.

When you pull the trigger, the hammer is released and it strikes the firing pin, hitting the primer. This sparks the gunpowder, sending the bullet down the barrel. This is where the gas system comes into the picture.

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:

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

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.

Company	View Stock
Bushmaster Firearms
DELTON
DPMS
Olympic Arms Inc

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.
