Trijicon 2200328 Mro Sd Coyote Tan 1X25Mm 2 Moa Red Dot Lower 1/3 Co-Witnes
Trijicon
The Trijicon MRO SD is a compact reflex sight purpose-built for rifle, carbine, and shotgun platforms that demand speed and reliability without bulk. This sealed miniature optic earns its place on modern fighting rifles and tactical carbines by delivering a clean 2 MOA green dot, fast target acquisition, and rugged performance in a footprint that won't weigh down your setup. The coyote tan finish blends naturally on desert or tan rifles, and the lower 1/3 co-witness mount positions it ideally for use with iron sights or underneath magnified optics.
The MRO SD refines the already tough original MRO with an upgraded objective lens and advanced coatings designed to pair seamlessly with magnifiers and night vision systems. The 2 MOA center dot is crisp and clean—large enough to find fast in dynamic shooting but precise enough for serious accuracy work. Eight illumination levels let you dial brightness to your light conditions, and the 2 MOA dot appears in both day and night modes, so your sight picture stays consistent whether you're training at noon or running night operations.
Build quality is serious: the housing is forged 7075-T6 aluminum with hard-anodized finish, windage and elevation adjusters that lock in your zero even under hard recoil, and full waterproofing rated to 100 feet submersion. The ambidextrous brightness controls are easy to reach with either hand, and a single CR2032 battery delivers three years of runtime on the day setting—set-and-forget performance that won't leave you fumbling in the field.

The MRO SD ships with a lower 1/3 co-witness mount. This height positioning allows you to see your iron sights through or below the optic window, making it a versatile choice for rifles that run backup sights or for transitioning between irons and the dot sight.
Yes. The MRO SD's enhanced optical design was specifically engineered to pair with magnifiers (such as the Trijicon MRO 3x Magnifier) and night vision systems. The green reticle and clean dot design work well in these configurations.
The sight uses one CR2032 lithium battery and delivers three years of continuous run time when kept on day setting 3 at normal temperatures (70°F). The eight brightness levels give you flexibility to extend battery life even further if you dial down the illumination in bright daylight.
Absolutely. The housing is fully sealed, hard-anodized 7075-T6 aluminum, and the optic is rated for submersion to 100 feet—far exceeding what you'll encounter in rain, snow, or wet environments. The sealed construction and durable finish make it reliable for serious hunting and training work.
