3006mv- You totally ommitted the CZ 452-2E ZKM "Trainer" whcih would be a very fitting and affordable model.
It accepts standard .22 groove rings for scope mounting- but they need to be high for bolt handle clearane. I personally have see-thru's because I get both height AND the ability to use the glorious iron sights that are standard on that model. The sights on the trainer model are excellent. In the last light rifle match I shot with mine (Scoped with a cheap 3-9x40) I scored out at 277/300 (target scores 89, 93, 95) on a course of fire consisting of 30 rounds, unsupported standing position, sling use not permitted @ 50 Feet. I came in second to another CZ shooter, who was using a CZ American model, with higher end optics and more expensive ammo- and the shooter is a very skilled and experienced 3P shooter. He scored a 278.
