    So I know it sounds like a bad thing to do, but I'm curious. I am a Student Gunsmith and i have been thinking about different ways to attach sights. I prefer using silver solder but I am wondering if there is a glue or epoxy that would be suitable. I know front sights are glued onto shotguns sometimes with Black Max, but could it hold up on a rifle? I have a sporterized 1917 Enfield in 30/06 that I like to use for experimenting. So does anyone have any input or suggestions?

    Red Green uses duct tape. Why don't you try that?

    Oh, now that was helpful.


    But seriously, I am interested in what other might offer for advise.

    you would have to have something that isnt heat sensitive. heat breaks down most glues and epoxies that are readily available. then you have the chemical problem when you start cleaning with solvents.

    there is a reason sights are attached via dovetail type cuts or screwed in or are part of a barrel band or sight base assembly

    The problem is over time it will break down. Then you add recoil to the mix and if you glue sights on a gun they will come off. Rear sights should be held on my screws and front sights should be held on with silver solder.

    The issue is not simply recoil. but the high frequency vibrations that run thru a barrel when you fire. As they hit the glue, density of material changes. Speed of that wave is a function of density (denser, faster). Wave gets reflected back on reaching the lighter material, meets second wave coming out, starts breaking epoxy.

    Will it work? Yeah. For a while. Then your sight falls off on the ground.

    If you're looking to experiment, you could try jb weld.

    sights


    I know it wasn't directly helpful, but indirectly it was. What I meant was, gluing will not work. Go some other more permanent route that others have suggested. It was pretty funny though.

    I have been told that JB Weld could withstand the heat and vibrations of firing a rifle. Although I am uncertain what the cleaning solvents I use would do to it. No one seems to know exactly how long it will last, but a few optimists said it could last as long as the rifle if done right.

    Try it with a really inexpensive sight. That way, when it falls off you haven't lost much.

    I would advise against ever doing it on a customers gun though, on the assumption that as a gunsmith, you would like to have customers.

    JB Weld is epoxy with metal dust in it. There is nothing magical about it.

    No normal gun solvents will have any real effect on epoxy. As a temporary fix, I think it would work OK. I could never recommend it as a permanent installation method.

    Slow drying epoxy is plenty strong for sight installion. Just degrease well. And rough up the contact surfaces. To remove just heat with a torch and twist off.

    Epoxy for site mounts

    Finally, someone making sense.
    "...heat ...vibrations ...last for a while then fall off" ??
    Firstly this is a solution for your own rifle only!

    In the case of my first N. trapline rifle. an old Rem pump with undrilled receiver, I JB welded a pivot mount and front site on this rifle. Since then it has been carried on horseback (bucked off once thanks to wolf on path), Argo, canoe and snowmobile. Notice the shiny 0% blueing finish? That doesn't come from hanging on the gun rack!
    Will fall off in time? Yeh, I don't think so. That was 1970 when I mounted that scope! My secret is to roughen up the surfaces (see quote) and use MEK (methyl ethyl keytone) as cleaner.

    Epoxies for scope mounts

    My old Rem pump mount may have been done with another epoxy, not JB. It was so long ago, I can't remember.
    More current... I've used this rifle for "only" 12 years! Hasn't fallen off yet.
