I have an older Savage in 20g/22mag. It has a small dovetail for a scope, but when I tried a scope years ago....the rings did not hold very well. I was wondering if anyone has seen something like what Cabela's offers for Benjamin air rifles...a two peice base that clamps around the top tube. If not...Is there some kind od bases/rings that will work securely on these? I would appreciate some help.
