Leupold Mark IMS - 35mm - 20 MOA - Scope Mount

The Leupold Mark IMS is a one-piece integrated mount and ring system machined from a single block of billet aluminum — eliminating the ring-to-base interface that creates movement, wear, and zero shift in two-piece mount systems. Purpose-built for AR-platform rifles on Picatinny rails, the Mark IMS in Dark Earth (FDE) delivers a rigid, repeatable optic mounting solution at a fraction of the weight of comparable steel mounts.

The Mark IMS is a one-piece scope mount and ring combination machined from billet aluminum, featuring a 35mm ring diameter, super high ring height, and Picatinny rail interface, finished in Flat Dark Earth.

Single-block machining removes every moving part between the rifle receiver and the scope — no ring cap screws compressing against a separate base, no tolerance stack between components, and no possibility of the ring shifting relative to the base under recoil or heavy use. The design provides up to four times more thread engagement than standard two-piece mount sets, with a full half-inch of thread length per fastener for exceptional clamping integrity. The super high ring height clears the flat top receiver and handguard of AR-platform rifles while centering 35mm tube scopes at an optimal cheek weld height. Billet aluminum construction absorbs shock and handles extreme temperature variation significantly better than steel mounts and at substantially less weight. Compatible with both left- and right-hand actions. Mounting hardware is included. Made in the USA.
