Hi Everyone, I had to buy a new barrel tenon for an older Marlin, I could not find an original anywhere. Anyway, the new tenon is the right length and height but is very loose. Any tips on tightening it?? I don't want to modify the barrel dovetail, only the dovetail on the tenon where it fits into the barrel. Any good glues, adhesives? Thanks!

I had this problem with a globe sight on an old 45/70 once. The way I fixed it was to get a set of feeler gauges at the auto parts store (about $3). Get a pair of tin snips and cut a small piece of each gauge that's close to the thickness you need and place it under the tenion and insert it into the dovetail. This will drive the tenion into the top of the dovetail creating the resistance you need. You'll find one with the correct resistance and use it. If you cut them carefully you'll never see them once the part is installed. There may be a better way, but that's how I handled the problem.

If the gap is not too large you can also peen/stipple the bottom of the tenon to expand it enough to grip.
Would help to know exactly where it's loose and by how much.

stipple the bottom of the dove tail and that will move the sight upward and make it tight..or as a last resort peen each side of the dove tail downward very carefully on the edges..or do both...

Thank you all for the reply's. I really apreciate it!

Oh man am I gonna get it for this one, but you can also use 5 minute epoxy, just a dot and clean any off with a toothpick. If you want to remove it just heat it, the 5 minute stuff loosens up pretty easily.

I know, not as traditional as center punching in a place or two, but it does not permanently alter either piece if that is important.

Just curious, but has anyone used any of the locktite products?
