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 firearm’s Mil-Spec 1913/Picatinny to raise the scope and push it forward, eliminating the need for risers or specialized optics with shortened eye relief. Mark 1 locks into place on the receiver with two, flush-fitting T-15 Torx® cap screws. All Leupold IMS products are tested to endure the rigors of the field and are covered by the Leupold Full Lifetime Guarantee.
