Call me crazy, dumb and dummer, retarded, old school or what ever, but I've used clear finger nail polish on my base and ring screws for the past 44 years. Guess how many screws have come loose on guns up to .416 Taylor??? ZERO!! And they come out reasonably easy with a tap of the hammer on a screwdriver in the screw.
Guess I'm too old to change, but if it works.....
