Owner’s Manual

Each of our Radial Delayed Blowback platforms are tested and designed to work with our matching components. The MkGs is designed to work with the 9mm or .40S&W uppers or BCG/Barrel combos. The MkG is designed to work with the .45acp uppers or BCG/Barrel combos. The Mk10 is designed to work with the 10mm uppers or BCG/Barrel combos. The Mk57 is designed to work with the 5.7×28 uppers or BCG/Barrel combos. We have only tested items that we manufacture and cannot guarantee the interchangeability or functionality with other manufacturers products.

If having read the above, and you still want to build your own variation, please note: We know that most PCC uppers will not work, due to the shortened ejection port and other lowers frequently need to have the ejector removed from them.  Any modifications needing to be made beyond that, we do not have a definitive list for as that can vary with the manufacturer specs.
