Very well made and strong. They fit the CZ 527 receiver perfectly and hold like a gorilla. Typical Leupold quality. These appear better finished and easier to use than the CZ brand rings which are even more expensive. The Leupold rings are a good value and Optics Planet was the only place that had a full selection of rings to fit the CZ, and all in stock.
Pros: Strong, Fit perfectly, Hold tight, Torx fasteners
Cons: Clamping to base can be a little tricky
