I have a Rem 870 police magnum that came with rifle sights instead of the front bead sight. The front sight recently fell off and I would like to know the best way to reattach it. The front sight can slide back into what looks like the rear dovetail of the glock, however it is loose and can slide right back out. What kind of epoxy or adhesive would be best suited for this task. Thanks Wanna kill these ads? We can help!
