Trijicon MRO SD 1x25 2 MOA Green Dot Sight, Black, Low Mount The Trijicon MRO SD 1x25 Green Dot Sight in Black combines an included low Picatinny mount with a compact 2 MOA green reticle. The lower mounting position is useful on compatible rifles, carbines and shotguns whose stock geometry calls for an optic close to the rail. A sealed housing and accessible brightness control make the sight a practical option for regular range and field use. Choose the Black Trijicon MRO SD Green Dot at BattleHawk Armory for a compact optic with an included low mount. Low Mount and MRO Fitment The included AC32067 low mount attaches to a compatible Picatinny rail and keeps the optic closer to the mounting surface. This can suit firearms with a lower stock comb or other geometry that calls for a lower sight line. Mount selection should follow your firearm and preferred head position, rather than an assumption that every rail-equipped firearm needs the same height. A low mount does not automatically provide co-witness with standard-height AR-style iron sights. Check the rail, stock geometry and any backup sights as a complete system. The sight uses the MRO optic-to-mount footprint, so a different compatible MRO mount can be selected separately if another height is needed. A 2 MOA Green Dot and Open 1x View The MRO SD is a sealed miniature reflex sight with 1x magnification and a 25mm objective. A single 2 MOA green dot provides a small, clearly defined aiming reference without a surrounding circle. The large aperture and short optical path give you an open view, while infinite eye relief allows more flexibility in eye position than a conventional 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 green-dot MRO SD is rated for 3 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. The low mount will not automatically align with a magnifier at full or lower 1/3 co-witness height. Choose a compatible sight-and-magnifier mounting arrangement with matching optical centerlines and adequate rail clearance. 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 green aiming dot; the housing color and reticle color describe different parts of the sight.

An AC32067 low Picatinny mount is included. Choose it for compatible setups that require a lower optic position; it does not promise co-witness with standard-height AR-style sights. Is the reticle green or does it change colors? The reticle is a single 2 MOA green dot. Brightness is adjustable, but the sight does not switch between red and green illumination. Can the MRO SD be used with a magnifier? Yes. The optics are designed for use with the Trijicon 3x magnifier, sold separately. The low mount will not automatically align with a magnifier at full or lower 1/3 co-witness height. Choose a compatible sight-and-magnifier mounting arrangement with matching optical centerlines and adequate rail clearance. Does the sight provide magnification on its own? The MRO SD has 1x magnification, providing an unmagnified view. A separate compatible magnifier is needed for a magnified view. Shop the Trijicon MRO SD Green Dot in Black at BattleHawk Armory.
