I’d take a few magazines and test fitment in the magwell for whatever brand you go with.
My aero precision stripped lower requires an unusual amount of force to both insert and remove several usgi aluminum mags I’ve tried in it (Center, Okay, NHMTG) It’s about 50/50. Some fit great, some require force.
Sent it to aero and they say it’s in spec. My plans are to file the magwell to get it to work with my “problem” mags like the other 5 AR15’s I’ve used them in.
Do yourself a favor, take a few mags and test fitment.
