Leupold Mark IMS 30mm Integral Mounting System - 1.5" Height - Matte Black

The Leupold Mark IMS (Integral Mounting System) is a one-piece cantilever scope mount machined from aluminum and finished in matte black. Designed to clamp directly to a rifle's MIL-spec 1913/Picatinny rail, the IMS provides an integrated ring-and-base solution that holds your optic at a fixed, repeatable position without the need to lap or align separate rings.

This model (part number 182871) is configured for scopes with a 30mm maintube and is built around Leupold's monolithic, single-bar-stock cantilever design used across the Mark 1 through Mark 4 IMS line. The mount sits at a 1.50" height, measures 6.04" long, and is built in with a 20 MOA cant to add elevation for long-range shooting. The included integrated rings clamp your scope securely using Leupold's recommended torque specs (65 in-lbs on the keeper clamp and 28 in-lbs on the ring top screws).

Weighing just 7.1 oz, the IMS provides a forward-mounted optic position with the elevated height needed for comfortable shooting on AR-platform rifles. It is purpose-built for AR-platform rifles and any firearm wearing a MIL-spec 1913/Picatinny rail, making it a clean, no-guesswork mounting solution for your 30mm scope.

Backed by Leupold's full lifetime warranty, the Mark IMS is a brand-new, factory-fresh mounting system ready to drop on your rail.
