Well IMO, and I know you get what you pay for, but $350 for a rimfire scope and rings is really high. That being said, you can get one of Cablea's rimfire scopes for a lot less and they are plenty clear and you can use the extra cash to stock up on 22 LR ammo once you find the type your CZ likes. I believe these scopes are either made by Tasco or Bushnell for them but I've been known to be wrong before. They make a straight 4X and a 3-9X. Nikon also makes a fine scope that Cabelas sells for $179.
