So I finally got to take my first build out... chambered one, and it's dead on accurate with irons as well as the PA m3 multi clone... the problem is the damn thing won't cycle. and by won't cycle I mean the carrier doesn't move at all. The only thing I can think of is that the front sight block doesn't match up with the hole... can any of you folks think of anything else? I'm about to tear it down and start investigating, but figured I'd check with the board before I started.
