Are you looking for the right AR-15 barrel for your rifle? If so, you’ve come to the right place. The first AR models appeared in the late 1950’s, and to some gun owners, the barrel is considered the most important part of the AR rifle.
Essentially, it doesn’t matter if you’re purchasing a new AR-15 rifle or a cheaper used model, your choice of a barrel will have a major impact on the rifle’s performance and accuracy. The AR-15 is preferred by many gun enthusiasts as the rifle of choice for hunting and target shooting — mainly because of its highly modular nature.
A great feature about the AR-15 is that it can also be customized to your preference — there are lots of options available for you to create one exactly as you like. But before you dive into your AR-15 barrel project, be sure to take a look at these essential functions to aid you in your research.

Next, we have the upper receiver. It houses the bolt and barrel of the firearm and is associated with the bolt carrier group, barrel extension, charging handle, and rail system.
The barrel length has a blunt impact on your accuracy. Available in lengths ranging from 7 inches to 24 inches, the 16-inch AR-15 is the most common. Moreover, rifle barrel lengths of 16 inches or greater do not require a Class Three tax stamp from the Bureau of Alcohol, Tobacco, Firearms and Explosives.
If you need to use your rifle for shooting at longer distances, a barrel that is longer is your best bet. It offers increased accuracy and sufficient pressure to enable peak ammunition acceleration.
A shorter, lighter barrel is a superior decision for moving in restricted zones or protecting your property from intruders. But, if you need to use your weapon for self defense or other reasons, a shorter barrel length will be your best option. Your rifle will be much more portable.
The profile refers to the barrel’s weight. It can be narrowed down to three requirements: lightness, heavyweight and for government use. The lightweight barrel is commonly called a pencil-type barrel, for obvious reasons and it’s perfect if you’re traveling long distances as it’s portable and easy to carry.
The heavier the barrel, the greater the resistance it provides to the buildup of heat when firing the weapon. The M4 carbine version is the most popular profile option. It offers an acceptable compromise for many AR-15 owners who prefer alternating between heavier and lighter barrels.
The government barrel is a bit like the M4, but it happens to be heavier due to the handguard area. Finally, there’s the heavy barrel. The heavier barrel provides awesome resilience to heat that may occur in the rifle as the gun is fired.
All gun owners most likely agree that a barrel should be of the highest quality. Why? Since it deals with much weight and heat each time the shot is discharged from the muzzle. AR-15 barrel construction styles include the cold-hammer forged, melonite, stainless steel and chrome-lined style.
The cold-hammer-forged process results in a tougher barrel with incredible resistance to wear and tear. However, they are quite expensive compared to the other types of barrels. Traditional chrome-lined barrels provide longer service life and good accuracy. Mil-spec AR-15 barrels generally include a lining made of chrome-polymer steel — mainly for longevity and cleanliness.
Most importantly, the chrome lining is useful for military purpose in high-dampness and saltwater situations because of the exceptional resistance to corrosion. The chrome will also protect the barrel against heat and friction — significantly helping to increase its lifespan. In addition, a chrome barrel is also easier to clean than a stainless-steel barrel.
The stainless steel barrel has no chrome lining, which is perfect for providing greater accuracy at longer distances. A stainless-steel barrel usually doesn’t contain a chrome lining, therefore it provides increased accuracy at longer ranges.
What’s the best twist rate with your rifle? To clarify, the definition of a twist rate is the ratio of how tight the spirals are in the rifle’s barrel. For example, a barrel with a 1:7 twist ratio enables a bullet to spin faster than one with a 1:9 or 1:12 ratio.

Overall, the thing to remember before you purchase an AR-15 barrel is simply, why do you need it? What is your purpose? When you decipher your ultimate goal, you can make the wisest AR barrel decision for your needs.
So, when it really comes down to it, your choice of an AR-15 barrel correlates with the reasons for owning and using an AR-15 in the first place. For example, if you purchase an AR-15 for the sole purpose of protecting your family or property from intruders, or for occasional target shooting, a standard-issue mil-spec barrel is basically all you need.
However, if you’re a competitive shooter or someone who needs maximum accuracy at long distances, a stainless-steel barrel without lining is the best choice for you. In conclusion, we certainly hope this review has helped you to make the best possible choice!
