Just about any AR-based PCC that uses an M16 style bolt should work with a DIAS. There may be some proprietary bolts out there that do not but most I've seen are profiled the same as an M16 carrier. No reason those shouldn't work as long as the sear trip face is in the same spot as an M16. Now if you're talking MPX, Scorpion, etc...yeah those won't work.

However, I assume OP is concerned whether or not the lower is milled out to 'low shelf' dimensions to accept the RDIAS and that could hit or miss depending on the MFG. I know the CMMG 9mm Guard is drop in.

Evidently there are mainly non-standard bolt carriers in these rifles. I think CMMG was one of the ones I called and they said no.

Macon uses a standard M16 carrier. It works sweet with my Echo II.

The New Frontier Armory AR-9mm standard bolt carrier is also M-16 configured as it has the sear-trip at the rear of the bolt carrier.
Therefore it would conceivably be rather easy to mill out one of their 7075 C-9 80% billet 9mm lowers to the low-shelf configuration to accommodate a RDIAS that would work with the New Frontier Armory bolt carrier. It goes without saying that all National Firearms Act regulations apply in such a situation. |
