Will this work with the CMMG RDB BCG and mk9 AR9 lower by CMMG? Expert Answer

Aero Precision states the Aero Precision EPC-9 Threaded Assembled Upper Receiver and EPC-9 in general are compatible with some parts from other manufacturers but recommends using all Aero Precision EPC-9 parts to ensure proper function. I recommend contacting Aero Precision in regard to the Aero Precision EPC-9 Threaded Assembled Upper Receiver and the CMMG RDB BCG.
