If the top of the dovetail measures 1/2", this ring will fit. If it is 3/8" on the outside, Talley does not produce a ring that narrow.
For that scope and rifle I recommend using the .6" high set of Talley 1in Rimfire Rings.
These rings are the 11mm dovetail rings. The rings you need will depend on the scope you are mounting to the CZ 452 Military Trainer. The guide below will help you determine what ring height you need.

Due to your objective lens being relatively small, you can use low height rings. So the Talley 1in Rimfire Rings that I would recommend using is MPN:22CZRL. These are designed to fit the CZ 452, 455, 457, 512, and 513. (11mm Dovetail).

Yes, they would be compatible.
