Leupold mounts are every bit as rugged and dependable as the Leupold optics they're intended to secure. With a huge variety of mounting systems, for nearly every type of firearm under the sun, you're sure to find the perfect match for you firearm, and your style of shooting. The Leupold Integral Mounting Systems (IMS) family quickly and easily eliminates the two most common issues faced when mounting standard rifle scopes 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. The Mark 8 Mount comes with integral rings and is designed specifically for the Leupold Mark 8 Tactical Rifle Scope. All Leupold IMS products are tested to endure the rigors of the field and are covered by the Leupold Full Lifetime Guarantee.
