Trijicon 2200302 Mro Sd Black 1X25Mm 2 Moa Red Dot Full Co-Witness Mount

The Trijicon MRO SD is a compact red dot sight built for hunters and shooters who demand speed and reliability without bulk. This 1x25mm reflex optic is engineered for rifles, carbines, and shotguns where fast target acquisition matters—whether you're hunting in tight timber, running drills at the range, or setting up a tactical platform. The MRO SD combines a large viewing window with a clean 2 MOA red dot reticle, giving you the situational awareness to track moving targets and engage quickly while maintaining that crucial full co-witness sight picture with your iron sights.

What sets the MRO SD apart is its re-engineered objective lens, which improves optical performance and plays well with magnifiers if you decide to stack glass later. The adjusters are robust—designed to hold zero under recoil and rough handling—and the sealed, anodized 7075-T6 aluminum housing will survive anything you throw at it. Eight illumination settings let you dial the dot brightness from bright daylight to low-light environments, and a single CR2032 battery powers the sight for up to 2.5 years of continuous use. You get full waterproofing down to 100 feet, which means rain, dust, and the occasional water crossing won't compromise your zero.

This package ships ready to go: the optic comes mounted on Trijicon's full co-witness mount, so it sits at the right height to align with your backup irons. You'll also get a lens cloth, manual, and warranty card. Weighing just 4.8 ounces, the MRO SD won't slow you down, and its compact footprint (2.9 × 1.7 × 2.1 inches) means it won't overhang your receiver or obstruct your charging handle. If you're building a no-frills, high-reliability setup that handles the field better than the garage, the MRO SD is a proven choice.

Frequently Asked Questions

What's included in the box?

The MRO SD comes with the optic already mounted on Trijicon's full co-witness mount, plus a lens cloth, manual, warranty card, and mount guide. No additional base required.

Will the MRO SD co-witness with iron sights?

Yes. The included full co-witness mount positions the red dot at the proper height to align with standard backup iron sights, so you can use both sighting systems together.

Can I use this optic with a magnifier?

The re-engineered objective lens on the MRO SD is designed with magnifier compatibility in mind, though magnifier compatibility depends on your specific setup and mounting configuration.

How long does the battery last?

A single CR2032 battery provides up to 2.5 years of continuous use when the optic is set to day setting 3 (the middle of 8 brightness levels) at 70°F. Actual runtime varies with illumination setting and temperature.

Is the MRO SD waterproof?

Yes. The fully sealed, hard-anodized housing is rated for submersion to 100 feet (30 meters), making it suitable for rain, splashing water, and field conditions.
