16″ 5.56 Black Nitride Carbine M-LOK Government Upper Assembly

Engineered for reliable performance in a compact package, the 16″ 5.56 Black Nitride Carbine M-LOK Government Upper Assembly is ideal for builders who want battle-ready quality without compromise. It features a 16-inch government-profile barrel with a corrosion-resistant black nitride finish, paired with a carbine-length gas system for fast, reliable cycling. A forged mil-spec upper receiver is matched with rugged, American-made M-LOK handguards (style may vary), and the assembly includes a nitrided A2 flash hider for reduced muzzle signature. With precise attention to build quality—such as Permatex 242 on fasteners and AEROSHELL 33MS on torqued interfaces—this upper is built to last. It’s proudly made in the USA and comes backed by a limited lifetime warranty, delivering guaranteed sub-MOA accuracy with match-grade ammunition and proper technique.
