Obviously, the most feature of any barrel is the accuracy.

If your rifle doesn’t shoot accurately, what point does it serve?

High quality barrels can go a long way in increasing the accuracy of the rifle.

Other features to keep in mind are the durability and the size. Certain metals will be more durable than others due to their chemical composition. A more durable barrel will last longer on your AR-15 build.

Unlimited Guide About Choosing A Best Barrel For Your Ar15

Barrel Materials

There are two main barrel compositions:

  • Chromoly Steel
  • Stainless Steel

Chromoly steel is an alloy. Barrels made from this material are the most inexpensive and are fairly accurate, but will not last as long.

Stainless steel barrels are more accurate by a comfortable margin. They will also last a little longer, because they are more resistant to corrosion. However, they are slightly more expensive and are heavier.

From there, some barrels are given either a chrome lining or nitride treatment.

Chrome lined barrels will last longer, but will decrease the accuracy.

The chrome lining will preserve the barrel and prevent corrosion even further. However, as the lining wears off, the accuracy of the barrel will be negatively affected. Nitride treated barrels will also last for a long time, but without the decrease in accuracy.

As far as the size is concerned, keep in mind the barrel length requirements in the United States (assuming that is where you are purchasing from).

If your barrel is shorter than 16 inches, your rifle will be considered a short barreled rifle, commonly referred to as an SBR. These weapons are covered under the National Firearms Act, and will require a tax stamp from the ATF. However, for our list, we will focus on 16 inch barrels.

Recommendations

For Competitive Shooting

If you are looking to do competitive shooting that requires extreme accuracy, stainless steel will be the best barrel for you.

The increased accuracy will be the most important for this type of shooting. Avoid chrome lining for competitive shooting, as the accuracy will degrade over time.

For Hunter

For hunting, accuracy is less important.

Especially if you will be hunting in a humid area or in the rain, resistance to corrosion is going to be crucial for this type of shooting.

The most important aspect of the barrel for this type shooting will be to ensure that the barrel is treated somehow, either with a chrome lining or a nitride treatment.

Both chromoly steel and stainless steel are resistant to the elements, so the treatment becomes the most important part for a hunting rifle. A hunter should have best ar15 bipod to hold your ar. 

For Casual Shooter

If you are just a casual shooter, it is dependent on how much you shoot.

If you shoot thousands of rounds per year, you probably are going to want a chrome lined barrel. It will last longer for you.

If you don’t shoot that much and clean your rifle adequately, any barrel choice will work for you. In this situation, we would recommend a stainless steel barrel due to the increased accuracy.
