I got some Polish blank firing mags from Poland a ways back before APEX had theirs and then got some from APEX also. This struck some questions though. I know my mag from Poland is definitely Polish but I'm wondering about the ones from APEX. My Polish mag is like all Polish mags in that the rear rib only extends to about 3/16" below feed lip piece and is paint over park. Now the APEX mags the feed lip goes all the way up and the mags are blued. Could the APEX mags be new old stock or are they possibly another country of origin?
