I just bought a CZ 455 22lr but it has no sights (it's a Varmit) and my scope has not arrived yet. I haven't found much on the forum about that model, but it seems that the CZs are supposed to be pretty accurate. My other choice was one of the old Winchester 52 series but I wasn't ready to fork out that much money on a 22. Once I get the CZ set up and get a little time in with it, I will report back. Right now, I am thinking that the finish could be better and the action seems a little rough. Also want to replace the OEM magazine and well which appear to be plastic! It's a heavy barrel which I like....I seem to be steadier with it. I spent more on the scope (Leupold) than the rifle, figuring that if I didn't like the rifle, I would still have a decent scope to mount on a different gun. Twisted logic...maybe...but I never claimed to be logical! LOL
