arkypete,
I would take a good look at the CZ Trainer or Lux (same thing as the trainer but with a Walnut as opposed to a beech stock). The Trainer has a tangent rear sight that is pretty slick. For around $18? you can get a ghost ring to replace the blade, And you will have the ability to remove & replace the scope.
I have/had all of the below. What I don't like about the receiver sights is the high front sights required, which I feel makes the set-up too fragile for use in the field a moot point if it is just for range work IMO.
There are four options for receiver sights;
1.) The Williams which is compatible with the Scout, had one... seemed a little fragile to me. Anything but the scout would need a front sight of some sort.
2.)The BRNO target receiver, Spendy ($150ish), compatible with the trainer/lux only. A Quality Target sight.
3.) The NECG Rimfire sight and the Tech sights. The tech sights have a front blade that is compatible with the lux/trainer. The NECG it has been so long since I had mine on I do not remember but think it needs a taller sight than the trainer/lux has.
Whichever model CZ you go with you will need to do something with the trigger. This ranges from the $18 yo dave kit to the $80ish Timney or Rifle Basix. All of which are user installable.
