Saw a CZ Ultra Lux in the gunshop and had to try it. Thought it would be a fun to shoot with the graduated open sights. The problem I have is the indexing on the sights does not come close when using standard high velocity 22LR ammo. The 25 yd shoots high at 50 Are these sights set up for standard velocity? There are no adjustments that I see other than setting the rear ramp to match the range you are shooting.
