CMMG® Mk10 Barrel and BCG Kits 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, slowing the BCG. This results in a lighter BCG for a lighter rifle, and less felt recoil than a straight blowback system.
Mk10 Barrel and Bolt Kits are designed to work exclusively with our Mk10 Lower Receivers.
