20″ 5.56 Phosphate Rifle M-LOK Government Upper Assembly

20″ 5.56 Phosphate Rifle M-LOK Government Upper Assembly

The 20″ 5.56 Phosphate Rifle M-LOK Government Upper Assembly is built for shooters who value accuracy, durability, and full-length performance. Featuring a 20-inch government-profile barrel with a mag phosphate finish, this upper delivers consistent results whether you're on the range or in the field. The rifle-length gas system ensures smoother cycling and reduced recoil, while the 1:9 twist rate offers flexibility for various 5.56 NATO loads. A low-profile steel gas block and nitrided A2 flash hider round out the performance-focused setup. Assembled with premium components—including a forged mil-spec upper receiver and American-made M-LOK handguards—this upper is treated with care using Permatex 242 and AEROSHELL 33MS for long-lasting reliability. Each unit is made in the USA and backed by a limited lifetime warranty, with sub-MOA accuracy achievable using match-grade ammo and proper technique.
