Maxima Fixed Rings are designed to be the strongest most durable fixed mount 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 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.
