Leupold 176886 Mark IMS 35mm

The Leupold Integral Mounting Systems (IMS) family quickly and easily eliminates the two most common issues faced when mounting standard riflescopes to AR-style rifles; scope height and eye relief. Each aluminum IMS cantilever design mounts directly to the firearms Mil-Spec 1913/Picatinny to raise the scope and push it forward, eliminating the need for risers or specialized optics with shortened eye relief.
