The CMMG 8" 9mm barrel and BCG kit allows you to build a pistol caliber carbine using the CMMG Radial Delayed Blowback System. Unlike typical direct blowback systems, Radial Delayed Blowback uses a bolt that is forced to rotate and unlock, slowing the BCG. This results in a lighter BCG and less felt recoil than a straight blowback system.

Good price, in stock. Trust Fortress Tactical. I emailed Mike a question this past Sunday morning, and he answered it that day.  You can’t beat that kind of service.
