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 Tikka Rings are able to fit right onto the receiver’s dovetail with no need for a mounting base. The Tikka Quick Detach Rings sport the unique Warne indexable lever system which allows the user to remove the optics from the rifle then reattach it without the loss of zero, as well as allowing the location of the lever to be indexed once the rings are affixed to the bases. After the levers are tightened, simply pull out on the lever, turn it to the desired location then let it snap into place. These rings also feature a redesigned recoil pin to provide a stronger bearing surface for higher recoiling rifles. Matte Finish.
