Maxima Fixed Rings are designed to be the strongest most durable fixed mounting system available. Typical steel scope mounts in this class use only 2 screws per ring have a narrower clamping band and in most cases only absorb recoil in the front ring. Maxima Fixed Rings utilize 4 T-15 Torx style socket cap screws for secure optics mounting. The Maxima Fixed Ring Series fit Weaver style cross slot bases and incorporate a Warne square stainless steel recoil control key in both the front and rear rings. This ensures a "no slip" 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 bases when used on softer or less durable materials. The Maxima Fixed Ring band is also substantially wider for additional clamping surface around the scope to hold the optic firmly in place. The Maxima Fixed Rings are available in a durable DuPont powder coat finish in either matte or gloss black and also an electroless nickel finish. Warne Maxima Scope Rings are designed to fit Warne bases as well as all Weaver cross slot and Mil-Spec Picatinny style bases and rails. * Permanently attaches to base. * Square recoil control key for positive engagement of ring to base. * Rings securely mount around scope using 4 Torx style T-15 socket cap screws 25 in/lb. of torque recommended.
