Thread: rear tang screw stoping bolt from moveing freely

just got my jw103 back from the gunsmith who installed my suppressor
when I got it home and put the bolt in, it now catches on the rear tag screw
don't think its really the smiths fault just shit wood compacting a little if I back the screw off 3/4-1 turn the issue goes away

what would be the best way to fix it pillar bedding I guess? any other ideas
