Nice rings - like all warne products - Warne Rifle scope 1 inch Quick Detach CZ 527 16mm Medium Rings

These rings worked well on my CZ 527. You do have to screw in the movable claws all the way in to successfully lock the rings on the 16mm dovetails, however, as I suspect these were meant to also work with other CZ weapons with 19mm dovetails. The only reason I didn't give five stars is because the rings can only be installed with the levers on the right side of the action; I'd prefer the levers be on the left side of the action.
