So my buddy finished a build recently and shot it (kinda) the other day. He's having problems and we can't figure it out and need help.
Seems to me he's getting light strikes and when it does shoot it short strokes. Hes determined the problem is in the upper. At first we thought it was the hammer spring but swapped and it shot fine. The only things I can think of is a misaligned gas block or something in the BCG. Gas rings.....What am I gonna look for in a block alignment issue? I'll try to get more info out here as it comes in. We're in text tag mode right now....
L one is from the build....
