Useful & easy to use - Leupold Scopesmith Ring Wrench for 30mm or 1" rings - 48762

It is obvious there are other ways to install the Leupold rings but this is the quickest, easiest and won't mar the finish. The amount of leverage is correct the fit is perfect. One does not need to attach the top half of the ring which other methods may require. I was initially skeptical as to whether I needed this but am a believer in it.
