Brutus what brand of mount would that be ?
Mark there is another thread (high scope rings for 11mm cz dovetail ?) there are some links in there that might be use full.
as you may have figured out most high and extra high are not high enough. the bell diameters of the scopes will also cause you grief.
there are some cheep Chinese aluminium ones that work , but I have not found steel.. Burris signature say they are high enough , but I have never seen them in Canada and the price is stupid, if you have to order them .
