What Is the Most Accurate Barrel for an AR15?

Ensuring accuracy is always the goal when shooting, and upgrading your gun barrel can help you accomplish this. Generally, longer barrels are more accurate, especially at range, as the more time the round has in the barrel to stabilize helps it stay on target while in the air. Additionally, increasing the twist rate of your rifle barrel can improve your accuracy, as it further helps stabilize the bullet in flight.

How Many Rounds Is an AR15 Barrel Good For?

AR15 parts are designed to be rugged and resilient, and the rifle barrel is no exception. Most modern, high-quality AR barrels can easily last for more than 20,000 rounds, so you can count on yours lasting for a long time. However, the exact life span of your barrel depends on many factors, including the type of ammo you use, how much powder is loaded in each round, and how often you clean the gun barrel.
