The Maxima Fixed Ring Series is engineered to offer unmatched reliability and durability for your outdoor adventures. Designed to fit Weaver style cross-slot bases, these fixed rings incorporate Warne's square stainless steel recoil control key in both the front and rear rings. This ingenious design ensures a no-slip, solid recoil surface across the entire slot of the base, capable of withstanding even the heaviest recoil. Additionally, the Maxima square recoil key safeguards against swaging or peening of bases made from softer or less durable materials. The ring band is substantially wider, providing additional clamping surface around your scope to hold the optic securely in place. Warne Maxima scope rings are crafted to seamlessly fit Warne bases, as well as all Weaver cross-slot and mil-spec Picatinny style bases and rails. These rings are designed to be permanently attached to the base, guaranteeing a rock-solid mount. The square recoil control key ensures positive engagement between the ring and the base. The rings mount securely around your scope using 4 Torx-style T-15 socket cap screws, with a recommended torque of 25 in/lb., ensuring maximum stability. Made from durable steel and featuring a sleek matte black finish, the Maxima Fixed Ring Series in high height (0.525" base to bottom of tube) and 30mm tube diameter is the ultimate choice for any outdoorsman seeking precision and enduring performance.
