Another possible suggestion. Thanks, Coffinmaker.
I've heard many uses for JB Weld on guns. Does it really work ... and last? I used long-drying epoxy once on a gun and the part loosened up slightly within less than 100 rounds. (The epoxy had about 6 month to cure, so I really doubt that was the problem - plus I was a fanatic when I cleaned off any oil from the parts, so I discount any oil infiltration as well.) I don't want the parts (an ill fitting front sight on the NMA I mentioned) to loosen completely, and I hardly ever shoot the gun anymore, so that's not a biggie. It's barely noticeable ... but I can tell. I'm just asking about JB Weld for the "long haul."
