Here is a SECRET that I will share only with you about

stopping a scope and rings from moving in a Magnum springer. If you tell any one about this simple but effective solution, Dozens of people will jump out and tell you it's IMPOSSIBLE and that Only by throwing many dollars at a problem can it ever be solved.
Have you clicked the "I Agree" box at the bottom?
OK here goes: 1.)Attention to detail is Paramount. 2.)Good Lighting and Magnification Mandatory 3.)You will need the following items, (no substitutions). LACQUER thinner or ACETONE, a good quality needle file, clean cotton rags, double sided carpet tape 3/4 in. wide.and at least one good Fingernail. I use Accushot 1" Med. Airgun/22 Deluxe rings.(cdnnsports.com).
Clean thoroughly the entire length of both scope rails repeatedly with solvent soaked cotton rag using your fingernail to press the rag deep in to the Bottom of each dovetail groove. Repeat this step at least 5 times until after rag shows no sign of any oil on it. Wrap rag over fingernail one layer and use fingernail as your tool.
Do the same on the clamping ring bases. Take needle file and at a 45' angle and flush with the flat clamping /mating surface file all the bluing off until you clearly see "scratch file marks" on these clamping surfaces.We are creating more surface friction with these angled 'Machine Marks' that will cause these "micro cuts" to dig into the degreased rails.(smooth things slide , rough things grab).
Cut your double sided black tape ("friction tape") to fit nicely in your scope ring cradles or wrap your tube if you know Exactly where you want it to end up in you final overall configuration. Ring cradles work best, more flexible.
Final test , I removed my S1k scope stop because I needed the room for my Simmons 6x18x40 AO to fit . AND my scope doesn't move.
