Warne Rings Features The Warne Rings are machined specifically to fit the integrated dovetail receiver design found on Ruger No. 1 Mini 14 Mini 30 and Blackhawk firearms eliminating the need for a separate scope base and simplifying the mounting process. A scalloped recoil control key on each ring positively engages the receiver s dovetail cut locking the rings in place and preventing shift under the recoil of centerfire cartridges. Four Torx style T-15 socket cap screws torqued to a recommended 25 inch pounds clamp the 30mm ring securely around the scope tube for a tight consistent hold. Once fitted the rings permanently attach to the receiver giving shooters a stable repeatable mounting platform built specifically for their rifle. Constructed from steel and finished in a durable matte black coating these rings are built to resist wear and corrosion through years of field and range use keeping the mount looking and functioning like new long after other hardware would show its age. The high-profile height provides adequate clearance for larger objective lenses while keeping the scope centered over the bore for consistent cheek weld and a repeatable sight picture shot after shot. Warne s reputation for precision machining ensures each ring is manufactured to tight tolerances for a proper fit against the factory dovetail so the mount seats correctly the first time without hand-fitting or aftermarket shims. For Ruger No. 1 Mini 14 Mini 30 and Blackhawk owners who want a dedicated no-base mounting solution these permanently attached Warne rings deliver a secure and reliable way to mount a 30mm riflescope for hunting ranch work or everyday range use.
