The Leupold Mark IMS Integral Mounting System for 34mm optics (part no. 176915) solves the same height and eye-relief problem the Mark IMS line is known for, sized up for the larger 34mm tubes now common on precision scopes. Leupold machines the cantilever mount from aluminum and bolts it directly to a MIL-STD 1913 Picatinny rail, pushing the optic forward so a 34mm scope lands at correct eye relief on an AR-style rifle without stacked risers. The integral rings mean nothing else to buy. Among one-piece scope mounts for 34mm optics, the Mark IMS is the rigid, no-assembly answer.

Key Specifications

• The mount fits scopes with a 34mm main tube, matching current large-diameter precision optics.
• Overall length is 6.01 inches, cantilevering the optic forward for proper eye relief on AR platforms.
• Mounting height is 1.50 inches, raising the optic for clearance and a comfortable cheek weld.
• Construction is aluminum, balancing low weight with structural strength.
• The mount attaches to Mil-Spec 1913/Picatinny rails, the standard AR-style mounting surface.
• The design uses a cantilever configuration, positioning the scope forward without added risers.
• The package includes rings, so no separate ring purchase is needed for a 34mm tube optic.

Frequently Asked Questions

Do I need to buy rings separately? No, the rings are integral to this mount, so a compatible 34mm scope is all you need.

Why does an AR need a cantilever mount? The forward offset restores correct eye relief on flat-top receivers, where a scope mounted directly over the rail usually sits too far back.
