The Leupold Mark IMS 35mm Integral Mounting System (MPN 176886 / UPC 030317021825) is a robust, one-piece scope mount engineered to secure large-tube optics with a 35mm maintube onto MIL-spec Picatinny rails, especially on AR-15 and modern sporting rifles. Its forward cantilever design addresses common scope height and eye-relief issues by positioning the optic forward and elevating the centerline approximately 1.40″ above the rail — matching classic AR sight height and providing a comfortable, natural cheek weld. Precision-machined from 6061-T6 aluminum with a matte black hard-coat anodized finish, this mount combines strength, repeatability, and ease of installation using a durable two-bolt system. Made to withstand recoil and field use, it’s ideal for tactical, precision, and hunting applications.
