Use Warne rings and bases. They are much stronger and more consistant and look ten times better than Leupold rings and bases.

I see too many Leupold rings and bases that do not fit properly. Dovetail rings that when installed rock back and forth on the base cause they do not get tight, dovetail rings that are too large to fit inside the dovetail cut out in the base, screws that are too long and must be shaved down so not to make contact with the bolt, inconsistancies with the thickness of the bases thus requiring shimming.

The only rings I hate worse than Leupold are Millett.
