Does this mean the screws are barely too long? If this was my rifle, i would shorten them screw ever so little, then install them with loctite. If they ever came loose again would be when i would try silver solder or some such thing.
I believe you wrote you have never tried loctite. When i fix things, i always try to use the easiest (non-gunnysack) fix, and go from there.
