Radial Delayed BCG Kit For Lesser Recoil And Lighter Performance
The CMMG MKGS Barrel and BCG Kit will allow you to build a Pistol Caliber Carbine using a Patent Pending Radial Delayed Blowback System. Unlike typical direct blowback systems, the 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.
The MKGS Barrel and Bolt Kits are designed to work exclusively with MKG Lowers, and a mil-spec upper receiver with an enlarged ejection port.
