ATTN: 9-mm AR Gurus
I haven't tried these in over a year, but I recall body 5 (a 40-rounder) working best, but still badly.
The backs of the mag bodies have a variety of cuts. I just don't know which one the intended correct magazine is supposed to have, because the kit used doesn't seem to have been marked anywhere.
Here's the hammer and bolt...it's a bit dirty (I was so disgusted with its performance that I didn't clean it). Anybody recognize the kit?
Update: Tam has a Body 5 magazine which she calls a Colt. I hope buying a brand-new Colt mag will solve my problems....
