Ruger Model Specific fit Sold in pairs, Maxima Ruger rings are packaged in model specific configurations to fit Ruger’s proprietary dovetail Warne’s Maxima Maxima rings are a solid steel, vertically split ring that handle even the most punishing recoil, or large, heavy scopes. Since each firearm manufacturer has their own proprietary mounting rail design, each ring model must be machined to exacting tolerances for proper fit and function. Because of this, the Warne Ruger Rings are able to fit right onto the receiver’s dovetail with no need for a mounting base. The Ruger Quick Detach are available to fit the Ruger #1 receiver design (which includes the Blackhawk and Mini 14 models) Ruger Fixed Rings utilize 4 T-15 Torx style socket cap screws for secure and permanent optics mounting.
