Left to right, Calhoun, Warne Medium, Warne Medium QD, Leupold Medium, Talley, Warne Tall, CZ Medium, and Burris Medium. The CZ 527 dove tail is 16mm. The lowest rings (Calhoun and Warne Mediums) have been known to cause bolt handle interference with the older/taller bolt handles and scope oculars. With a 3-9X Leupold and the new style bolt handle I think (dont actually know) your okay with any of them.
