CMMG .40 S&W Barrel And Bcg Kit

The CMMG 40 S&W MkGs 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 pistol or rifle, and less felt recoil than a straight blowback system.
