Did you get an answer on this?
If not, my suggestion would be the Burris Signature Zee rings with a set of the J&P delrin dovetail adapters. I suspect that the 'high' rings will work better than the 'medium'. In addition to the clearance between the objective bell on the scope and the barrel, with CZ rifles you need to watch the clearance between the ocular bell of the scope and the bolt. If you want to only mess with them once, the highs should be fine.
The model number for the 1" Burris rings in matte blue in high is 420531. Website:

You should measure the dovetail before ordering the J&P adapters. CZ 452 Americans
almost always have the 3/8" dovetail, but there are occasional reports of a rifle with a dovetail width different than what it's supposed to have. The CZ 3/8" dovetail is 3/8"
at the bottom, narrowest part of the dovetail and is about 13mm across the flat top. The other CZ dovetail (used on the Varmint, Style, Silhouette and other models) is 11mm across the top.
The advantages of the Burris Signature Zee rings are several. They use a precision nylon insert that surrounds your scope, so there is no metal to metal contact and you don't get 'ring marks' on your expensive scope. That insert can pivot in the ring, so the inserts are self-aligning, meaning that there is no need to lap the scope to achieve perfect alignment of the rings. Finally, you can change the inserts to provide adjustment in elevation, allowing you to maintain the scope's internal mechanism as close to the optical center of its range as possible, or allowing greater MOA adjustment at longer ranges.
This is not the cheapest alternative, but the Signature Zee rings do things that no other ring does and that makes them worth a few bucks extra for me.
