CZ 550 Quick detachable 1 inch, one piece scope rings and dovetail mounts manufactured by Talley.. These rings are made specifically for a 1 Inch diameter scope on the CZ 550 model rifle and can be used with or without the quick detach levers.  Talley CZ 550 Quick Detachable (QD) rings are designed to fit the CZ 550 series, including Magnum and Safari Classic models, which feature a 19 mm integrated dovetail receiver. Because they fit this specific 19 mm dovetail, they also accommodate CZ 557, CZ 537, select heavy-centerfire BRNO actions, and Heym rifles that utilize the same 19 mm standard.  The price is 150.00 firm.
