We wanted to build an affordable upper assembly without cutting corners. This means using a nitrided steel gas block from an American Manufacturer as opposed to aluminum, quality American Made handguards and using a proven M16 profile phosphate BCG paired with a NBS Premium Series 16″ Mid-Length Barrel.
We use Permatex 242 on key components while using mil-spec AEROSHELL 33MS Anti-Seize grease on the barrel nut and muzzle device.
