CMMG Barrel with Bolt Kit 9mm 16" RDB Black

CMMG Barrel with Bolt Kit 9mm 16" RDB Black

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.

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.
