Beware of height numbers! - Leupold RM Rimfire No Tap Rings

Excellent set of rings for my CZ-455. All steel, solid, beautifully made. Just remember Leupold lists their ring heights from the top of the base to the CENTER of the rings. Many other manufacturers do so from the base to the BOTTOM of the rings. This makes for a .5" difference on 1" rings. I had been buying other brands recently and forgot about it. Had to return my Medium rings and replace them with High due to my mis-calculation. Wish all ring manufacturers would have a common measuring system, where somebody's High is not somebody'else's Medium...

Anyhow, very nicely made rings, machined very precisely.
