Trijicon MRO SD 1x25 2 MOA Red Dot Reflex Sight, Black, Lower 1/3 Co-Witness Mount

Trijicon MRO SD 1x25 2 MOA Red Dot Sight, Black, Lower 1/3 Co-Witness Mount

The Trijicon MRO SD 1x25 Red Dot Sight in Black includes a lower 1/3 co-witness mount for a more open central viewing area with compatible iron sights. Its single 2 MOA red dot keeps the reticle simple, while the reengineered objective supports optional magnified viewing. The compact sight suits a range rifle that needs a durable optic with a clearly defined mounting height.

Choose the Black Trijicon MRO SD Red Dot at BattleHawk Armory for a compact optic with an included lower 1/3 co-witness mount.

Lower 1/3 Co-Witness Mount and MRO Fitment

The included AC32069 lower 1/3 co-witness mount secures the MRO to a compatible Picatinny rail. With compatible standard-height iron sights, this taller arrangement places the iron-sight line in the lower portion of the optic window. That leaves more room around the center of the sight picture while keeping the irons visible through the optic.

Lower 1/3 co-witness describes the relationship between compatible iron sights and the viewing window. It does not guarantee the same result on every firearm. Confirm the rail and sight geometry before purchase. The optic itself uses the MRO footprint, while the supplied base provides the Picatinny rail interface.

A 2 MOA Red Dot and Open 1x View

A single 2 MOA red dot keeps the MRO SD reticle easy to understand. The 1x optical system provides an unmagnified view through a 25mm objective, and the large aperture helps the sight picture feel open. Infinite eye relief gives you flexibility in eye position and suitable rail placement without the fixed eye distance associated with a magnified riflescope.

Eight Brightness Settings and CR2032 Power

An ambidextrous brightness dial lets you select illumination with either hand. Eight levels include five daylight settings, one extra-bright setting and two settings for compatible night-vision equipment. Manual selection lets you choose how strongly the dot stands out against the scene. The low illumination levels support use with night-vision equipment; the optic does not generate a night-vision image itself.

One CR2032 lithium battery powers the LED. The red-dot MRO SD is rated for 2.5 years of continuous use at day setting 3. Brightness and operating conditions affect actual battery life, so that rating should be understood with its stated setting. The long runtime reduces the frequency of routine battery changes.

Reengineered Optics for Optional Magnification

The MRO SD objective was designed for improved optical performance with the Trijicon 3x magnifier. A matching magnifier adds a closer view of the target while retaining the sight's dot as the aiming reference. Match the magnifier mount to the lower 1/3 co-witness sight height and allow enough rail space and eye relief. A magnifier is sold separately. Explore the Trijicon MRO 3x magnifier with flip-to-side mount when planning an expanded setup.

Forged Housing and Protected Adjusters

A forged 7075-T6 aluminum body protects the optical and electronic components. Fully sealed construction is waterproof to 100 feet, supporting use in wet outdoor conditions. Windage and elevation adjusters sit below the surrounding housing and require no protective caps. Their recessed position helps reduce snagging and accidental contact, while 1/2 MOA clicks provide defined adjustment increments.

The Black exterior coordinates with a wide range of equipment. Its matte appearance surrounds a red aiming dot; the housing color and reticle color describe different parts of the sight.
