Problems Hand Cycling
My gun doesn't want to hand cycle rounds. I have 3-400 rounds thru the gun. It will cycle 1200fps shells without issue. I took it apart and cleaned it getting ready for a match Saturday and tried to hand cycle rounds after cleaning and found that the rounds get stuck as they are going into the chamber at about a 45deg angle. If I pull the bolt back slightly the round will pop up and chamber. This is not magazine specific as I tried several mags. I have checked the feed lip dimensions on all the mags and they are the same. I have polished the feed lips on the mags.
Any ideas?
