They have standardized the receiver groves its called a 455.the 452 are built on different receivers .if you bought a 452 with intentions of putting a scope on it you should have gotten the american or varmint.
Receiver sight and call it a day. The perfect mannlicher setup.
Folks put scopes on all of the CZ models, I don't know anyone that shoots with open sights anymore.
There is a place in the USA that has made a weaver base just for the 452 which is supposed to fit the Burris Z rings very well. FS
