CMMG MkG Guard 45 ACP 16" Barrel and Bolt Carrier Group Kit Black

CMMG Inc Barrel and Bolt Carrier Group Kit .45ACP 16 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. While the CMMG GUARD 45 was design for .45 ACP we have tested it and are proud to say that it is safety rated to fire 450 SMC. Our MkG Barrel and Bolt Kits are designed to work exclusively with our MkG Lowers. Other manufacturers lowers may work but we cannot guarantee function or reliability.
