Meprolight USA Picatinny Riser RMR Footprint .40" Saddle Height Matte Black Aluminum Mount

The Meprolight USA Picatinny Riser is a precision optic mount purpose-built to secure RMR-footprint pistol red dots onto any rifle or shotgun equipped with a MIL-STD 1913 Picatinny rail. This 901141045 variant carries a .40" saddle height for shooters who want a low-profile mounting solution that brings a pistol-sized reflex optic up to a comfortable, fast-acquisition sight picture on the AR platform.

The mount is CNC machined from solid 6061-T6 aluminum and finished in a durable matte black hard-coat anodize that resists corrosion and keeps glare to a minimum. The top interface accepts the popular Trijicon RMR pattern along with any pistol reflex optic built to the same footprint, giving you a secure, recoil-resistant mounting platform well suited for duty, competition, or defensive setups on the AR and other Picatinny-equipped long guns.

Lightweight yet rugged, the riser clamps directly to a standard Picatinny rail and locks the optic in place with a repeatable, rock-solid interface built to hold zero through recoil and repeated handling.
