I recently did a PCSL 2-gun competition and it was awesome! But .223 is costly enough for me to just want to run 9mm for competition.

I tried doing some research on 9mm conversions in general but found most info was old, items were out of stock (Aero is now defunkt?) and info was all over the place.

Anyone have leads on how to convert a milspec AR (I have the IC-DI) to a 9mm PCC? I assumed a full upper swap was all that was necessary, but without Aero available I am at a loss.
