Trijicon MRO SD Red Dot Sight – Co-Witness Mount

The Trijicon MRO (Miniature Rifle Optic) SD is a sealed reflex sight designed for rifles, carbines, and shotguns where rapid target acquisition matters. It features a single 2 MOA dot reticle with eight brightness settings plus two night-vision compatible modes, optimized for close-quarters to mid-range shooting. The SD (Submerged and Dustproof) designation indicates testing to 30 meters underwater.

Built with fully multi-coated lenses for maximum light transmission and a forged 7075-T6 aluminum housing that's both lightweight and exceptionally durable. The adjustable brightness dial sits on top for quick access. Includes a co-witness mount that positions the optic at absolute co-witness height with standard AR-15 iron sights. Powered by a single CR2032 battery offering up to 5 years of continuous use at mid-brightness. No parallax distortion beyond 50 yards.
