Back to hog-back stocks and scopes and cheek weld.... here's how I try to mount my scopes on a CZ with the hog-back stock. This as a 3-9x40 AO (Weaver V9) on a 452 FS. In the interest of low mounting and sight clearance, I've removed the rear sight (not the mounting boss) from the gun. Removing the sight takes only a few seconds because it just slides into the boss along with an integrated leaf spring, and re-installing is equally quick. If you don't want to remove the sight you can use a shorter scope and mount it behind the sight.
