Leupold 176883 Mark IMS Matte Black Integral Mounting System

The Mark IMS family easily eliminates the two most common issues faced when mounting standard riflescopes to AR-style rifles; scope height and eye relief. This model is designed to fit your AR's MIL-spec 1913/Picatinny rail and any scope with a 34mm maintube. Its angled design also adds 20 MOA of elevation. Designed specifically for use with ARs, IMS mounts features a forward cantilever design, placing your scope forward on the rail to provide you will a full field of view. The mount also places the center of the optic 1.5 off the rail, the same height as open sights on a classic AR, making it easier to look through your scope without struggling to get low enough to the stock.
