Strong, lightweight, aluminum mount attaches to the Ruger® factory ring cuts and requires no drilling and tapping. Uses three, steel, recoil pins to prevent “scope flyoff,” and accepts Weaver-style rings or mount systems such as used on Tasco 40mm red dot optics. Super Redhawk™ .44 Mag fits only the .44 Magnum and can be installed without removing the front and rear sights. Features a matte, silver, anodized finish. Super Redhawk‡ Casull is similar in design, but uses the rear sight notch as a recoil lug to allow the frame and mount to take maximum recoil. Fits .44 Magnum, .454 Casull, and Ruger™ .480 models with removal of the rear sight. Available with black, anodized finish.
