Built with compatibility in mind, Colt’s 11.5" Government Profile Barrel fits any standard "mil-spec" AR-15 / M16 / M4 upper receiver, and it’s chambered for 5.56x45mm NATO, so it will also safely fire civilian .223 Remington ammo as well.

Colt was the first supplier of AR-15 / M16 rifles to U.S. military. Nobody has more experience with the AR platform! Why build your next AR-15 with anything less a Colt barrel?
