Trijicon MRO SD 1x25mm 2 MOA Green Dot Reflex Sight - Lower 1/3 Co-Witness Mount

The Trijicon MRO SD is a sealed, 1x reflex sight built around a 25mm objective lens for fast target acquisition on rifles, carbines, and shotguns. The large objective lens provides a 44% larger viewing area than typical micro red dots, helping with situational awareness and quicker sight picture transitions.

This MRO SD features a crisp 2 MOA green dot reticle with an adjustable LED powered by a commonly available CR2032 battery. Adjustments click at .50 MOA per increment with a generous 70 MOA elevation adjustment range, and the sealed housing is waterproof to 100 ft / 30 m for confidence in adverse conditions. Eye relief is effectively infinite, and the unit measures just 2.90" long at 4.80 oz.

The included Lower 1/3 Co-Witness Mount (AC32069) lets you drop the MRO SD directly onto a standard AR-15 flattop and co-witness with your fixed iron sights. The compact housing, rugged sealed construction, and practical footprint make the MRO SD a duty-grade red dot well suited to defensive, patrol, and recreational shooting alike.
