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

The Trijicon MRO SD (Miniature Rifle Optic Sealed Defense) is a compact red dot sight with a green 2 MOA dot, designed for close-quarters to mid-range shooting on rifles, carbines, and shotguns. The green dot provides enhanced visibility in bright daylight and varied lighting conditions, making it ideal for tactical applications, home defense, and competition where fast target acquisition is critical. The low 1/3 co-witness mount allows for absolute co-witness with iron sights while maintaining a comfortable cheek weld on AR-15 platforms.

Built with Trijicon's proven MRO platform, this optic features a sealed housing with adjustable brightness settings, a large objective lens for a wide field of view, and aircraft-grade aluminum construction. The fully enclosed design ensures waterproof and fogproof performance in all conditions. Turrets are recessed to prevent accidental adjustment, and the battery compartment is top-loading for easy access without removing the optic from the rifle. The mount is included and provides a solid, repeatable zero on Picatinny rails.
