Leupold's Mark IMS 35mm Integral Mounting System solves two of the most common issues faced when mounting riflescopes on AR-type platforms: scope height and eye relief. It features a forward cantilever design and places the scope forward on the rail to provide a larger field of view, and positions the optic 1.5 inches off the rail - the same height as open sights on the classic AR platform. This makes it easier to use the scope without struggling to get low enough on the stock. In addition, the Mark IMS 35mm Integral Mounting System is constructed from durable aircraft grade aluminum, and features an FDE finish.
