I have an old Remington model 512 .22 rifle. It's a beautiful, very accurate rifle and has been in the family since new. Lately I've been having a problem with it feeding properly (it's a tube feed system) and I found a thread telling me how to adjust the carrier and it cleared up the problem. Now for the question........... Once the screw is adjusted and you work the bolt a few times the screw moves and it no longer feeds. The problem is corrected by staking the screw (using a punch to score the head of the screw locking it in place). Should I stake the screw or use Loc-tite on the threads? I know there is a couple different types of Loc-tite, one that can be used if you are planning on taking the screw back out later. Rather than messing up the rifle I thought I would run it pass here so what do you think? This is not a biggie but asking a simple question is much better than trying to correct a mistake.
