The Colt LE6933 Replacement Barrel Assembly 11.5in is a genuine factory AR-15 barrel built to match the original LE6933 profile. Chambered in 5.56x45 NATO, this government-contour barrel features an 11.5 inch length with 1/2x28 muzzle threads, making it ready for compatible flash hiders, brakes, or suppressor mounts. The assembly includes the front sight tower, front sight post, barrel nut, and sling swivel, giving builders an OEM-correct solution for refreshing a well-used carbine or completing a short-barreled rifle project.

This barrel is configured for a carbine-length gas system and uses six-groove rifling with a 1:7 twist to stabilize a wide range of modern 5.56 projectiles. M4-style feed ramps and a chrome-lined bore help enhance reliability and resist corrosion over extended use at the range or in training. Ideal for shooters seeking a compact AR-15 setup for general range work, drills, or practical competition, the LE6933 barrel assembly reflects Colt’s long-standing reputation for consistent quality and dependable performance.
