Well, I am not sure of you current ring hieght or bases. But what I recommend is a set of Leupold standard bases and "High" rings. Go to
http://www.leupold.com/resources/Mou...rt/default.asp
and pick the Leupold VXII 3-9X50mm or VXIII 3.5-10X50mm and your gun. I know the ziess and leupold are a tad different, but it would be a good substitute. They will tell you the proper ring part number and height.
