Sig Sauer Alpha3 Features The Sig Sauer Alpha3 is machined from proprietary aluminum with an exactness that delivers both strength and ductility allowing the integrated anodized aluminum rings to form securely around a riflescope without damaging the tube under proper torque and installation. The anodized aluminum rings provide protection and durability against the elements gun oils and cleaning solutions for long-term reliability and consistent zero retention through sustained field and range use. At a 1.54 mount height the Alpha3 positions a 30mm scope at an optimal height for a wide range of rifle platforms with Picatinny receivers. The Alpha3 30mm FDE one-piece Picatinny scope mount features a Flat Dark Earth finish that pairs naturally with FDE and earth-tone rifle builds and accessories for a cohesive aesthetic across any FDE-configured rifle platform. The proprietary ring design ensures a secure damage-free grip on the scope tube for consistent zero retention through the recoil and handling demands of sustained field and range use. Whether used on a precision bolt-action an MSR or a hunting rifle the Alpha3 delivers a reliable purpose-built mounting solution for 30mm scope tubes.
