The Trijicon MRO SD is a compact red dot sight engineered for shooters who need fast target acquisition without magnification. This miniature reflex optic fits rifles, carbines, and shotguns, delivering the speed and situational awareness that matter in hunting, defensive shooting, and the field. The MRO SD builds on Trijicon's reputation for rugged, dependable glass—built around a fully sealed, hard-anodized 7075-T6 forged aluminum housing that shrugs off weather, recoil, and rough handling.
What sets the MRO SD apart is its thoughtful optical design. The large 25mm objective and tapered light path create a wider usable viewing area than traditional mini reflex sights, so you see more target and more of what's around it. The re-engineered objective lens improves optical clarity and plays nice with magnifiers if you decide to stack glass later. Eight illumination settings—powered by a single CR2032 battery good for 2.5 years of continuous use at typical daylight brightness—let you dial the 2 MOA red dot from dim indoor spaces to bright sunlight. Windage and elevation adjusters are recessed and improved for repeatability; they're designed to hold zero through drops and recoil better than previous generations.
The package includes a low-mount base, so it sits low on your receiver for lower cheek weld and cowitness with iron sights. Adjustment is 1/2 MOA per click across a 70 MOA total travel range. Eye relief is infinite—place your head naturally and the dot is there. At 4.8 ounces and just under 3 inches long, it adds next to nothing to your rifle's weight or profile. Submersible to 100 feet, it'll stay dry and clear in rain, snow, and water crossings.
The MRO SD is purpose-built for shooters who want a no-fuss optic that works in any light, any season, and any terrain. If you run a rifle or carbine and you're tired of complex glass or sluggish target pickup, this is the sight to consider.

Frequently Asked Questions
What's included in the box?
The MRO SD arrives with the low-profile mount (AC32067), a lens cloth, the MRO manual, warranty card, and mount guide. The sight itself is ready to install.
How long does the battery last?
A single CR2032 lithium battery will run the sight continuously for 2.5 years when used at day setting 3 (the typical daylight brightness level) at 70°F. Actual battery life will vary based on which illumination setting you choose and ambient temperature.
Can I use the MRO SD with a magnifier?
Yes. The re-engineered objective lens on the MRO SD is designed to work with magnifiers, so you can add a 3x or 5x magnifier behind it if needed.
How much elevation and windage adjustment does it have?
The MRO SD has a total adjustment range of 70 MOA and clicks in 1/2 MOA increments, giving you plenty of room to dial zero on rifles with different barrel twists and engagement distances.
Is the low mount the right choice for my rifle?
The low mount is included and positions the optic low on the receiver. This allows cowitness with iron sights and a lower cheek weld. If your rifle's geometry requires a different height, you may want to explore other mount options—contact us for fit guidance.
