20" 5.56 Gov / SOCOM M-LOK Upper Assembly

20" 5.56 Gov / SOCOM M-LOK Upper AssemblyThis is a high-quality 20-inch upper assembly that works as well as it looks. It is built using a top-tier mil-spec forged upper receiver, a 5.56 Mil-Spec Steel Black Nitrided Barrel, an APOC Armory black Nitride steel gas block, a quality American-made M-LOK handguard (handguard style may vary), and a top-of-the-line Black Nitride A2. With this Government Contour barrel chambered in 5.56 with a 1:7 twist and a rifle gas system, it boasts a higher velocity and a longer sight radius. We always take the extra time to ensure the upper will function properly and reliably. It is built with Permatex 242 on key components while using mil-spec AEROSHELL 33MS Anti-Seize grease on the properly torqued barrel nut and muzzle device.This is an excellent product at a great price from an industry leader.
