Colt's commitment to quality and excellence are evident in every piece that leaves the factory. This complete upper assembly is no exception to that rule. Built from the factory as a complete upper assembly kit, not stripped from a rifle outside of the factory, you can rest assured you are purchasing a genuine Colt product. The upper features a 14.5" barrel with a 1:7" twist rate, polymer Handguards and A2 front sight base. The included bolt carrier group is full auto capable when using a select fire lower receiver, but will work just fine in semi auto lowers as well. This is the same upper issued to elite units and special forces units around the world. All NFA rules apply.
