Does AR barrel length affect accuracy?

Length. The barrel length has a direct impact on muzzle velocity and accuracy. AR-15 barrels are available in lengths ranging from 7” to 24”, with 16” being the most common. If you will be shooting at longer distances, a longer barrel offers increased accuracy and sufficient pressure to enable peak ammo acceleration.

How often does an AR 15 barrel wear out?
