The Colt AR-15 Upper Receiver Assembly with Monolithic Rail comes complete with charging handle, bolt and bolt carrier assembly. Featuring a flat-top upper receiver with plenty of picatinny slots that offer the shooter maximum versatility when it comes to mounting accessory devices. Unique to this upper receiver, is the free float monolithic rail which is machined together in conjunction with the upper receiver portion of the upper assembly.
