Talk me out of epoxy scope rings

First off my 338 edge kicks less than the 22-250 (no exaggeration) and it ran great with the light scope after switching to the heavy scope I ran in to issues...... I had to abandon signature rings and the base constantly coming loose so I switched to a DNZ similar to the one that had held the light scope but accommodating a 20moa cant and 30mm tube. That did not hold it so I added powdered resin which did not hold it......... epoxy bedded base to receiver and went back to signatures this time with resin and it did not hold it. OK now I am done screwing around so I got not one but two sets of leupolds and to my horror they where different heights despite being "identical parts"........... I lapped one of the rings down to match the other pair and installed the three rings with resin................................... held for a while but still slipped and right at the beginning of hunting season. OK now I have $hundreds$ in the dam mounts...........I do just so happen to have two matching sets of weaver 6-hole tactical rings, I have a lapping bar some jb weld and/or devcon steel putty......I think I actually have a reverse recoil impulse and unless some one has a better Idea I am going to have scope rings bonded to a scope real soon. Any suggestions? Thanks...........Duke

Re: Talk me out of epoxy scope rings

Are the rings you are using steel by chance? Aluminum rings have a higher coefficient of friction on aluminum scope tubs then steel rings. I don't like the idea of gluing scopes to rings myself.

With quality rings properly torqued with quality surface area (lapped rings) maybe even adding a 3rd ring, you should be able to hold the scope in place with out glue.

Re: Talk me out of epoxy scope rings

First rings had poly inserts(burris signature), second rings with integral base (DNZ) were aluminum, leupolds where steel, lapped and included a third ring. Powdered resin was employed to aid grip on all of the above after they failed without it............So far nothing has held more than about eighty rounds with the big scope. I know a glue in sounds extreme especially with four rings but I do not know what else to do. I do not like the Idea either but It looks like I am going to try it.......... Thanks, Duke

I think you need to move up to a quality scope mounting system like Seekins or Near Manufacturing both rings and bases.

Re: Talk me out of epoxy scope rings

I shoot a RUM 300 and stuck a 3x12 S&B scope on it. When I first started shooting it, I couldn't get it to group. I quickly realized the scope was moving in my Burris Signature rings. I pulled everything apart. After cleaning my Leupold dual dove tail rings and bases with the ring locked in place, I filled the underside portion with gel bedding glass and let it set up. After I reinstalled them I put the scope in place where it was originally sighted in. On the bottom of the top inserts I smeared a thin layer of 3M General Automotive Trim adhesive. I also used a Q-tip to put a bit on top of the scope and let it set according to the can's directions. I then put it back to together and tightened everything down and let it set up for several days. I put a barely noticeable pencil mark on the top of that heavy old scope at the ring so I could instantly tell if it was moving. It's never moved since. That was 10 years ago...

Re: Talk me out of epoxy scope rings

I would be tempted to try a dot of green Locktite 290 on each of the bottom ring halves and snug it up. You could still get it apart but I doubt it would move.

This can be done with the rings assembled as green Locktite is a self-wicking type.

"I think you need to move up to a quality scope mounting system like Seekins or Near Manufacturing both rings and bases."


Not to dispute quality machining and products.................... but....... with the base level and square and very secure, the rings lapped for perfect alignment, what is there to be gained?....... NOT BEING a SMART ASS, as I am the one looking for help so I mean it as an honest question. What might they do that the proposed system can't?


Green locktight, 3m auto trim......I am still taking notes and insight, Thanks everyone keep it coming if you agree or got something else, or anything I am missing.............Duke
