CMMG MKGS Barrel 9mm 8" Black AR Rifles - 99D517A

CMMG Inc Barrel and Bolt Carrier Group BCG Kit 9mm 8 in Salt Bath Nitride Black. Unlike typical direct blowback systems our RDB uses a bolt that is forced to rotate and unlock slowing the BCG. This results in a lighter BCG for a lighter rifle and less felt recoil than a straight blowback system. Our MkGs Barrel and Bolt Kits are designed to work exclusively with our MkGs Lowers. Other manufacturers lowers may work but we cannot guarantee function or reliability.
