Leupold Mark IMS 34mm 20 MOA 1-Piece AR Scope Mount Matte Black

The Leupold Mark IMS (Integral Mounting System) is a rugged one-piece scope base and ring combo engineered specifically for the AR-platform rifle. Machined from 6061-T6 aluminum with a non-reflective matte black finish, it provides an exceptionally solid, repeatable mounting platform that integrates the base and rings into a single, lightweight unit.

Designed to clamp directly to a rifle's MIL-spec 1913 / Picatinny rail, the Mark IMS features integrated 34mm rings paired with a forward-cantilever design that pushes the scope out for proper eye relief and cheek weld on modern sporting rifles. A built-in 20 MOA of elevation is machined into the base to give long-range shooters the additional internal adjustment needed to reach out to distance.

This model sits at a 1.50" ring height and measures 6.01" overall, weighing just 7.1 oz. Installation is straightforward thanks to a heavy 2-bolt cross-clamp design that delivers consistent, repeatable mounting torque to the rail (65 in-lbs keeper clamp / 28 in-lbs ring cap), so you can remove and re-install the optic without losing zero.

Whether you're topping an AR-15 with a high-magnification variable for precision work or running a 34mm LPVO, the Leupold Mark IMS offers a clean, low-profile mounting solution purpose-built for the flattop AR.
