Somervre Posted February 12, 2025 Posted February 12, 2025 (edited) I have an M2 field 12 gauge. The fiber optic front sight keeps loosening up. If I tighten so it’s lined up it’s not tight enough and then the next shot loosens it. If I tighten down snug it would be out of alignment. Any suggestions? Edited February 12, 2025 by Somervre Quote
Steve Rose Posted February 13, 2025 Posted February 13, 2025 Unscrew the sight and take it out of the rib. Clean off/degrease the threaded shaft. Add a drop of blue Locite (thread locker), fingernail polish or 5 minute epoxy on to the threaded shaft. Screw the sight back in place and lined up straight. Let it set and cure for a few hours.
