i had a smith take a weaver base and mill out the underside to slip over the weird dovetail mount the spr has and then tap holes in the the flat part on top of the scope mount on the rifle to correspond with the holes in the mount.milling the mount is much easier than tearing down the rifle to mess with it, and not to mention the mounts are alum and easy to work with. the rifle was basically unchanged except for the threaded holes in it.ive sold the rifle but still have the mount, if your interested i could maybe hunt it up and send a pic or two to ya.
