BUY Colt AR-15 Upper Receiver Assembly 5.56x45mm 16″ Barrel

They’re ideal for hunting, plinking and competition shooting. This upper assembly comes complete with Magpul adjustable flip-up rear sight, charging handle, bolt and bolt carrier assembly. Featuring a Picatinny-style Flattop, this upper is more than ready to offer the shooter maximum versatility when it comes to mounting accessories or optic devices.
