Colt, I purchased a CZ 452 FS in .22LR about five years ago. I always wanted a nice .22 bolt action rifle and I always liked the wood-to-muzzle stocks so when I saw that CZ made one I put it on the wish list.
I learned about CZ rimfire rifles over at www.rimfirecentral.com
where they have a big following. Based on info on that site I ordered a "YoDave" trigger shim/spring kit. For less than $20 my CZ trigger went from pretty good to "wow".
Can't help you with a scope choice as the FS is best used (in my opinion) with iron sights. Maybe one day I'll pick up an "American" and put a decent scope on it.
