Barrel parts include a .308 A2 Type Birdcage Flash Hider with Crush Washer; Rifle length .308 Gas Tube; Gas Tube Roll Pin; and a Lo-Pro Gas Block which is taper pinned on to the barrel. As the Midwest Industries KeyMod Forend has its own proprietary barrel nut which is already installed on the barrel by our gunsmiths, this kit also includes a special Midwest Industries barrel nut wrench and tube of green Loctite to be applied to the exterior of the barrel nut to help the handguard stay firmly in place.
