This 11.5" AR-15 Pistol Barrel is perfect for a featherweight build due to its Lightweight Profile that eliminates all excess weight and bulk, resulting in an easy-carrying, fast-cooling and lively-handling rifle. Additional features include a Chrome Lined Chamber and Bore for enhanced wear and corrosion resistance and a Carbine Length Gas Port. The barrel's 5.56x45mm NATO Chamber is fully compatible and safe for use with both surplus mil-spec and commercial ammunition, while its 1 in 7" Rifling Twist Rate is ideal for use with medium to heavy weight projectiles of up to about 77 grains. Proudly manufactured in the USA.
