Good choice David - These have a great reputation for their accuracy, for sure. Yes, you can mount a scope of your choice on this fine rifle, and you'll just need the rings (to fit the 11mm dovetail on this gun, versus the 3/8" dovetail on many guns). I'm sure you'll enjoy punching some paper with this one!

Yes you will need 11MM rings The ring height will depend on the scope

David, yes it can. The 11mm Dovetail would just need a medium height Rings : budsgunshop.com/catalog/product_info.php/products_id/41662/warne+22+caliber+medium+scope+rings+w%2fmatte+finish

David, The CZ455 has an 11 mm dovetail on top of receiver. Lots of options.--http://forum.accurateshooter.com/threads/cz455-scope-rings-and-mount-advice.3812485/
