    I recently put a scope on two 22lr rifles; a little Marlin tube fed semi-auto and a single shot Chipmunk for my grandson. The scope won't stay put on either of the two rifles. The recoil walks the scope forward on the mount until it comes off. I've been shooting for over 40 years; I know how to mount a scope, I've done this before. Has anyone else run into this problem or better yet has anyone else found a solution?

    Sounds like the scope ring base and the mount (weaver?) arent a good match. One or both may be worn, out of spec or both. Being a cheap ass and that being a .22, first thing I would try is flexible shim material like soda can alum. Cut it to fit where the rings meet the mount, double layer it if you have to. Being softer material than the rings and the mount, it should crush. lock tite the rings screws and cinch up. New rings might be in order though.

    Try either takin some paint off the rails, deepen the grooves a little w a triangle file or do both

    One scope is a Redfield and the other is a Simmons both on standard rimfire dovetails and rings. If I left anything else off just let me know please...

    Wow, you guys are faster than the web site. It wasn't showing any replies until I posted that second message. I agree with both of you that the fit isn't tight enough. However, In both instances the screws are as tight as they can go. I could remove some metal from the scope ring side or put in a shim. I'm not confident of my ability to make it look right with no sharp edges. Is this a common situation?

    Yes it is. Easy way to get rid othe sharp edges is to cut the excess aluminum away from the outer edges of the rings w a sharp new razor blade

    A drop of RTV silicone or Blue Loctite under the mount/rings works wonders ;)

    I would get different rings. They are the problem and while you could maybe fix them why try? Rings are fairly inexpensive and you have many brands to choose from. Buy some name brand rings and put the problem to bed.

    Many rimfire accessory rails are well known for slide...its just that there is little purchase unless you REALLY crank down on them...
    its like attaching a scope to a knife blade...Whether you buy Weaver or cheap no-name rings, they'll still slide without a little something extra.

    DIP offers the perfect rail to resolve the issue...yeah, the ad sez Marlin, but it fits anything with a 3/8" accessory rail.

    But as cheap fixits go...a drop of Loctite/Blue RTV solves the problem for ages...

    OK, is the scope walking forward in the rings, or are the rings backing up on the dovetail. If the scope is walking forward, a thin strip of duct tape on the inside of the rings will cure it. If the rings are walking backwards on the dovetail an adapter base and Weaver rings will take care of it.

    sharpen the bevel (claw where the rings meet the rifle's scope grooves). some rings dont go deep enough into the grooves
