Maxima Fixed Rings are designed to be the strongest, most durable fixed mount system available. They utilize 4T-15 Torx style socket cap screws for secure optics mounting and square stainless steel recoil control keys in both the front and rear rings. This square key provides a positive recoil surface across the entire slot of the base and is capable of withstanding the heaviest of recoil. The Maxima square recoil key also protects against swaging or peening of the base when used on softer or less durable materials. The Maxima Fixed ring band width is also substantially wider, which offers more ring to scope clamping area to hold the optics firmly in place. These Maxima Fixed Rings are provided in a durable DuPont powder coat finish in matte black, gloss black or silver. Warne Maxima scope rings fit all Warne bases as well as all Weaver cross slot and Mil-Spec Picatinny style bases and rails.
