    Lock-Tite on a Shotgun?

    I have a very well used 870 express 12ga. (actually my first "big" gun I got when I was 15) that has an issue. This gun literally has 10000's of rounds through it and has the war scars to prove it...lol. The piece that screws over the magazine tube that holds the barrell on is loose. It will tighten down but works its way loose after a couple shots. I don't feel safe shooting it. I thought about using some automotive Lock-Tight on the threads as I think they are just well worn on the magazine tube. Didn't know if anyone has had this issue a solution?, or has used anything like this on a firearm.

    I thought about just buying another 870 , but this gun just holds way too many memories of my Dad and my youth.

    Thumbs up

    Loc-Tite is a good choice. It won't harm the metal and it should hold screws and things in place. I've got an 870 and haven't yet put Loc-Tite onto the mag tube cap, because mine is fairly tight; though, I surely will when it has broken in fully.

    Maybe wrap the threads with some teflon tape? Other than that, alot of Loctite wouldn't be good. The blue Loctite I've used sparingly on scope mounts and small screws and it's semi-permanent. If the thread/screw fit is that loose, I don't think Loctite would do you much good. Maybe your local gunsmith has a box of parts and an old end cap? Other than that you may want to drill and tap a small hole for something small like 6/32 through the cap and tube to hold it in place.

    I would use teflon tape as well. Too much lock would make it difficult to take it off when you need to.

    How about fixing it right.

    Less than 20 bucks in parts to do it right.

    Loctite is commonly used to keep screws from coming loose. Just don't use the permanant. Use the mid grade available at auto parts and hardware stores.
    A little heat will soften up the stuff enough to remove the screw. Or you could change the parts.

    You have got a lot of good response on this one. The new parts are the best way to go. I just wanted to let you know that I have found that clear finger nail polish holds up really well, and it dries clear! Still $20 bucks for new parts sounds really good to me!

    Y'all be safe now, ya hear!

    That's the right answer. Thread locker & tape will just leave a fargin' ugly mess down the road.

    If there is a local machine shop in your area or even a good retired home machinist you can have the holes re-tapped with new threads for larger size screws.

    It is usually an easy and inexpensive job.
