Re: M2 carbine won't run
Something important to know: Did the carbine ever work before? That will tell you a lot. Might also check the springs in it, disconnector spring might be bent or weak. Very likely the problem is with a single part being out of spec, but we need to know if it fired auto back in the 60's. Any idea?
What kind of ammo are you using-- GI, commercial factory, reloads, overseas made steel cased stuff?
