Default CMMG RDB system (9mm)

Hey all. So in my quest to build a reliable 9mm AR I stumbled upon the CMMG 9mm radial delayed blowback system. Does anyone know if this barrel/bolt combo will work in a spikes 9mm glock lower?

This is what im talking about:

Our MkG GUARD Barrel and BCG Kit 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 and unlock, slowing the BCG. This results in a lighter BCG for a lighter rifle, and less felt recoil than a straight blowback system.

Our MkG Barrel and Bolt Kits are designed to work exclusively with our MkG Lowers, and a mil-spec upper receiver with enlarged ejection port. Other manufacturers’ receivers may work, but we cannot guarantee function or reliability. For more information regarding fitment, check with our Tech Support team.
