Permanent Cross-Slot Stability.

Steel rings that are based on the proven cross-slot design.

Uses the Leupold® QRW™ bases or any other Picatinny-style mounting rails.

Very fine Weaver rings, but perhaps a bit more tricky to work with, as far as mounting the scope.

Alloy rings are machined from a single piece of aircraft-grade aluminum so they are incredibly strong, yet lightweight

Also available in good 'ol steel

Mark 2 IMS 30mm Integral Mounting System In stock!!

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
