Trijicon 2200303 Mro Sd Black 1X25Mm 2 Moa Red Dot Lower 1/3 Co-Witness Mou

The Trijicon MRO SD is a compact reflex sight built for shooters who demand speed and reliability on the line or in the field. This 1x25mm red dot sight pairs fast target acquisition with a rugged sealed design—ideal for AR platforms, carbines, and shotguns where quick sight picture and situational awareness matter. The MRO SD's re-engineered objective lens delivers sharper glass and plays well with magnifiers, while its lower 1/3 co-witness mount position lets you keep iron sights in play if your setup calls for backup aiming options.

The housing is built from 7075-T6 forged aluminum and hard anodized to military spec, surviving the recoil, drops, and weather that come with serious shooting. Trijicon's improved windage and elevation adjusters lock your zero down tight, resisting the shift and drift you'd see from lesser designs. The 2 MOA red dot gives you a crisp aiming point without obscuring distant targets, and eight illumination settings—powered by a single CR2032 battery good for 2.5 years of continuous use—handle everything from full daylight to low-light hunting scenarios.

Ambidextrous brightness controls keep your shooting hand on the gun, and the large aperture and tapered light path maximize your field of view for the kind of situational awareness that matters in dynamic shooting. At 4.8 ounces and just under 3 inches long, the MRO SD won't burden your rifle or slow your transitions. Sealed to 100 feet and finished in matte black, this is a miniature reflex sight that refuses to compromise on durability or optical performance.

Frequently Asked Questions

What mount does the MRO SD come with, and can I use iron sights?

The MRO SD ships with a lower 1/3 co-witness mount, which positions the red dot at the same height as backup iron sights, allowing you to use either aiming system depending on your needs and preference.

How long will the battery last?

A single CR2032 lithium battery will run continuously for 2.5 years at mid-range brightness (setting 3 of 8) under standard conditions. Actual runtime varies with illumination setting and environmental temperature.

Is the MRO SD waterproof?

Yes. The sight is fully sealed and can be submerged to 100 feet (30 meters), making it suitable for wet-weather hunting and tactical use.

Will this work with a magnifier?

The MRO SD features a re-engineered objective lens designed for magnifier compatibility, allowing you to pair it with a quality flip-to-side or fixed magnifier for extended-range work.
