The Leupold Mark IMS Integral Mounting System for 30mm optics with 20 MOA (part no. 182872) is built specifically for AR-style rifles, angling the rail forward to solve height and eye-relief limitations while adding elevation for long-range dialing. Leupold machines the forward-cantilever mount from aluminum, with the optic centerline set at 1.50 inches above the rail to match common iron-sight height for a natural cheek weld. Integral rings ship with the mount, and the matte finish matches typical AR builds. Among 20 MOA scope mounts for AR platforms, this Mark IMS is built for competition, tactical, and general-purpose 30mm optics.

Key Specifications

• The elevation is 20 MOA, providing additional built-in elevation for long-range zeroing.
• Mount length is 6.01 inches, positioning the optic forward for eye relief and field of view on AR platforms.
• The optic centerline sits 1.50 inches above the rail, matching common open-sight height for natural cheek placement.
• Construction is aluminum, keeping weight low without sacrificing strength.
• The mount attaches to MIL-SPEC 1913/Picatinny rails, standard on AR-style platforms.
• The design is a forward cantilever, placing the scope forward without additional risers.
• The finish is matte black, reducing glare and matching common AR finishes.
• The mount includes rings, so a separate ring purchase isn’t required.

Frequently Asked Questions

Why 1.50 inches of height specifically? That height matches common AR iron-sight height, giving a natural cheek weld without a raised comb or riser.

What is this 20 MOA cant good for? It shifts long-range elevation correction into the mount, preserving more of the scope’s own turret travel for distant shots.
