45D855E : Barrel and BCG Kit, 16" 4140CM, SBN, 45ACP
Our MkG GUARD Barrel and BCG Kit allow you to build a Pistol Caliber Carbine using our Patent Pending Radial Delayed Blowback System. 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, and a mil-spec upper receiver with enlarged ejection port. Other manufacturers' receivers may work, but we cannot guarantee function or reliability.
Due to governmental regulations or manufacturer preferences, some product lines or items may be not be available to export in your country.
Following a manufacturers price increase, we reserve the right to change product prices at any time without further notice.
