You mount the scope with a set of rings only, no base cause the base is already on the rifle. The CZ 550 Full Stock takes the same scope rings as the CZ 550 American. You can order a set from CZ, or go to GunBroker.com and type in CZ 550 in the search engine window. You'll see there are several folks selling the rings. Talley also sells rings for the CZ 550 in both Full Stock and American, so does Warne (I may have screwed the spelling up on that one). Tom Purdom
