Integral Mounting System (IMS)

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. From the Mark 1™ to the Mark 4®, 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. All Leupold IMS products are tested to endure the rigors of the field and are covered by the Leupold Full Lifetime Guarantee.

• The Mark 1 Rail slides into place and the living hinge easily clamps to the rifle with two Torx T-15 screws, providing an affordable and easy-to-use alternative to risers which do not push the scope forward.
• The Mark 2™ Rail provides the same advantages as the Mark 1, with the added benefit of ½” keeper nuts for quick-release removal and return to accuracy.
• Mark 2 Integral Rings are available in 1” or 30mm diameter, eliminating the need for separate scope rings or risers.
• The Mark 4 line takes versatility to the extreme, providing modular components for interchangeable adaptability.
• Use the Mark 4 Base in conjunction with the 20-MOA Integral Rail insert, 1” Integral Ring insert, 30mm Integral Ring insert, or to securely attach the Leupold Mark 4 CQ/T® or HAMR™ directly to the firearm.
• ¼-32 screws hold any of the inserts or optics to the Mark 4 Base with rock-solid dependability, while allowing additional extension for various weapons system/optic combinations.
• The Mark 8 34mm IMS Mounting System is regulated under ITAR
