scope mounts for a simmons white tail and a cz american .17hmr

[dazzyboi]

I think they are 3/8"

Have a look at the faq on http://cz452.com/

Thats for the American, not the American Varmint.

It doesnt make sence? it refers to the CZ American 452 to have 11mm dovetails, the proceeds to state that some models (Classic) has the 3/8 " dovetails

Done a search on this forum and alot of people were having problems with incorrect alignment with these mounts.
