I'm looking for some good scope rings for my CZ-452 in .17hmr. A friend gave me a Bushnell 4-12x40 Sportsman series scope for free I'm looking to stick on it. I've never really dabbled in scoped rifles so looking for whats good. The gun doesn't have the easiest life, more of a throw in the vehicle in case I want to put a hole in something closer than ~250yrds. Looking to use the existing dovetails on the receiver, and didn't know if there was anything that was the hot shit, or something to stay away from.
