I have some Weaver style scope bases and the Rings I have the base screw goes all the way across the ring. I need just the slightest bit more adjustment and with the rings I have they have to fit in one position due to the slot cut in the base for the tightening screw in the ring base. Are there other rings that don’t use this center screw that can use more of the adjustment range on the scope bases or is this something for recoil to prevent the rings from moving? If so, I will need to opt for a scope with more room between the lenses. Sorry if my description is not that great. My rimfire uses a dove tail and the rings can “pinch” anywhere on the rail. This other rifle the bases are set in one position and with the rings and the base screw there is one position for each ring. That doesn’t give me enough room to fit the scope I want to use. Outside of a new scope are there some other rings to look at?
