Hey Lochlainn, I use this mount on my Ruger Blackhawk. http://www.opticsplanet.net/leapers-airgun-22-full-length-integral-high-profile-mount-rgpm2pa-25h4.htmlI don't have any shifting of any kind, all rock solid steady. Get one of these, clean the dovetail real well with denatured alcohol, add mount and tighten well. Add scope and stir in a little blue loctite. Let it season for 24 hours then take it out and enjoy.Recipe for success....LOL.Happy Shooting!!!!Dave
My AH shoots 903 and have no trouble with the supplied scope. At present I am installing a Vortek Kit. I found the spring to be broke slightly on the piston end and the crimped end of the sleeve was completely busted out and missing. Did find small pieces of metal inside. Seal nicked. So good thing I decided on the Vortek. And am looking for a replacement piston as the rod was also loose from the seal end.
I took it off to photograpg. There is a small ding in the end, a sign it hasn't moved much and the scope stop is doing what it's supposed to.
I have an early Air Hawk without the stop. I used the Leapers 1 piece and drilled a hole for the pin just to be sure. Why not try removing the stop and see if you can use the hole that is there?
good idea jim , but that wont work i tried. i currently have my bug buster mounted on a accushot "off set" mount. i just backed it right up to the stop, its the rock of jabralter, now the trick is the blue locktite and YOU MUST NOT MESS WITH IT FOR 24 HOURS! i know its hard but its a must! i just mounted a bsa 3-12x44 on my heavily mod'd walther and let me tell you, longest day of my life
