Trijicon MRO SD Red Dot Sight – Low 1/3 Co-Witness Mount

The Trijicon MRO SD (Miniature Rifle Optic Sealed Defensive) is a sealed red dot sight designed for close-quarters to mid-range engagements on rifles, carbines, and shotguns. It features a 2 MOA red dot reticle with eight brightness settings (two night vision compatible), optimized for rapid target acquisition in defensive and tactical applications. The MRO SD comes pre-mounted on a low 1/3 co-witness height mount, positioning the optic for a heads-up shooting posture while allowing backup iron sights to be visible in the lower third of the window.

Built on Trijicon's battle-proven MRO platform, this optic uses fully multi-coated lenses for clarity across a wide field of view. The sealed housing is waterproof to 100 feet, shockproof, and runs on a single CR2032 battery with up to 5 years of continuous use at medium brightness. Turret adjustments are 1/2 MOA per click with audible and tactile feedback. The housing is machined from forged 7075-T6 aluminum with a hard-anodized finish.
