·Thinking about going 9mm with my next build. Not sure of the best way to go. You have the RRA/Colt upper, as well as the Oly upper. I like that the Oly setup uses a standard lower. No special hammer etc. Also the RRA setup can be a bit finicky at first with the uzi mags. Or..may go the RRA route, use a drop in block, and pop in a 32 round pro-mag.
This is pretty sweet.
