Custom gunmakers have long sought the quality and durability of Talley mounts. Available for magnum and standard calibers, the Talley system features CNC-machined rings of 2024-T4 aircraft-quality aluminum or cold-rolled carbon steel. Precision tolerances ensure a precise fit where the ring and base contact. The double recoil shoulder base is rock solid and will withstand the repeated pounding of our largest magnum cartridges. All screws are heat-treated to prevent breakage.
