was at the range awhile ago and one guy was having lots of problems with his sks, so the guy next to him went to help him out and the problems persisted. so i offered my help to the two guys and looked at the sks, it was full of cosmo and grease and had never been cleaned and they could not figure out why it would not work... handed it back and told him its done for the day take it home and clean it...total slam fire canidate.
