Good morning to all!! I'm slowly moving towards starting my first CETME C build, and as a rank beginner I have what may seem to be a dumb question (the first of many, probably!! ). As I start pressing the barrel into the trunnion, if, God forbid, I find that I've pressed it in too deep, do I a) keep pressing it the same direction, right on through the trunnion, or b) press it back out the direction that it came from? Thanks for your expertise!!
