Colt AR-15 Complete Upper Assembly .223 Rem/5.56 NATO 16" Barrel A2 Flash Hider Flip Front Sight Black Description
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 16" barrel with a 1:7" twist rate, a gorgeous monolithic free float quad rail and flip 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.
