Got a deal on a CZ 455 American (NiB) in .22 LR.
Bought CZ 1 inch rings (11MM - Product Number: 19001) (approx. .625" high) and installed them per supplied torque spec's.
Installed a Nikon Pro-staff Rimfire (3x-9x).
With the elevation pegged at maximum I'm shooting about 2 feet low at 25 yards. I haven't had time to pull the scope, swap the rings around, etc., but does anyone know if the CZ rings are the same height, or is there a distinct front and rear (which doesn't seem to be marked, as far as my old eyes can determine)?
