The Colt LE6933 EPR II Complete Upper Kit (brand part no. LE6933-EPRII-CK) brings the 11.5-inch Commando-length top end from Colt‘s Enhanced Patrol Rifle line to builders who want genuine factory Colt hardware on their own lower. Chambered in 5.56 NATO, the 11.5-inch barrel is the classic compact patrol length — fast handling in vehicles and doorways while keeping the reliability Colt’s duty guns are known for. As a complete kit, it gives an AR pistol or registered short-barreled rifle project a proven, duty-grade upper without piecing parts together.

Frequently Asked Questions

Is an 11.5-inch upper kit legal to buy? Yes, an upper by itself is not a regulated firearm. Install it on a pistol lower or a registered short-barreled rifle; putting it on a rifle-configured lower first requires an approved ATF Form 1.

Will it fit a non-Colt lower? Yes, it installs on any standard mil-spec AR-15-pattern lower receiver.
