hi all im a new saiga owner and im having an issue. I converted it to pistol grip and i installed a relabilty kit new puck and gas plug the problem is with the 12 round mags when its fully loaded and i attempt to chamber a round the round seems to be leaving the mag at a angle that catches right before it enters the barrel if i just push down on the round the bolt will close but if i take 3 or 4 rounds out of the mag it doesnt happen any ideas thanks everyone
