Yea! I finally got around to shooting my no ban rra 9mm flattop yesterday. I slapped on an Eotech, and loaded up my Uzi mags. I was using a non-modified Hy-tech mag black, and the fit was tight.
The rifle shot great, had only one mis-feed that was a result of a uzi mag not seated correctly. I will be contacting Hy-tech for the new mag release shortly.
