NBS 16″ 5.56 Phosphate Midlength M-LOK Lightweight Upper Assembly - $159.95

Description

A quality upper assembly without cutting corners. This means starting with a top tier mil-spec forged upper receiver, using a low-pro steel gas block, quality American Made M-LOK handguards and one of the nicest nitrided A2s you’ll find anywhere. This also means taking the time to ensure that the upper will function reliably. We use Permatex 242 on key components while using mil-spec AEROSHELL 33MS Anti-Seize grease on the properly torqued barrel nut and muzzle device.
