I got to examine GunGeek's SKS and I think I may know the problem. The piston seems to be pretty loose in the tube, with more clearance around the outside than my Norinco, which is pretty tight. I think the gasses may be going around the piston more than they should, and not applying the full impulse necessary to cycle the action.
Does it sound like a good idea to try my Norinco gas system on it to see if it fixes it? If so, Gungeek could get a new tube and/or piston, such as Tapco's American made combo.
