Tikka rifles have a grooved receiver that allows for a dovetail ring to mount directly to it, negating the need for a base. Warne's Maxima Tikka rings are a solid steel, vertically split ring that handle even the most punishing recoil, or large, heavy scopes. The Tikka Quick Detach rings utilize 4 T-15 Torx style socket cap screws for secure and permanent optics mounting and also feature a redesigned recoil pin to provide a stronger bearing surface for higher recoiling rifles.
