Cmmg's 9mm barrel and bcg kit allow you to build a pistol caliber carbine using cmmg's patent pending radial delayed blowback system.Unlike typical direct blowback systems, 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.Their barrel and bolt kits are designed to work exclusively with mil-spec ar-15 upper receivers with a modified ejection port, like their mkg/mkgs upper, and most mil-spec ar15 lowers when used with 9 ar conversion mags as well as their mkgs mk17 and mk9* lowers.Other manufacturers receivers may work, but we cannot guarantee function or reliability.*older mk9 lowers will require one of their retrofit kits to convert it to a radial delayed blowback compatible lower, instead of traditional blowback.
