I use a trio of the Leupold 1-4X's on three of the CZ 527 Full Stocks and a 1.5-5X Leupold on a 7.62X39mm Carbine. The Full Stocks are all in Cahoun Hunker rings and the Carbine is in Warne medium QD mounts. Both these ring mounts are among the lowest available and may give you problems with the older style (taller) bolt handle.
