The Leupold Mark IMS 30mm 20 MOA scope mount is an integral mounting system for AR-style rifles, finished in matte black (Leupold part no. 182872). Its aluminum cantilever design mounts directly to a MIL-spec 1913 Picatinny rail and pushes the scope forward and up. That solves the two common problems of mounting a standard riflescope on an AR, scope height and eye relief, without risers or a short eye relief optic. It is one of the 30mm versions in Leupold’s IMS family.
