Thread: Help required - scope rings

Looks like the bevel on that clamp hasn't been made properly or it's inverted, You said you tried turning it 180 degrees.
I've used Warne ring's on my CZs and they work well, they don't fit perfectly, but have never had them move.

The CZ 452 American and Varmint are not a proper 3/8" dovetail, they are 3/8" at the base of the dovetail but the angle is different so the top of dovetail is wider than standard. You can get rings that fit this perfectly, I know Leupold make them and call them 13mm rings.
Don't know why they didn't just do a proper 3/8" dovetail?????
