Quick Overview

MkG GUARD Barrel and BCG Kit allow you to build a Pistol Caliber Carbine using the 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.
