Trijicon 1x25 MRO HD Red Dot Sight - Matte Black, 68 MOA Reticle with 2 MOA Red Dot, Low Mount

The Trijicon 1x25 MRO HD red dot sight is a compact, sealed reflex optic built for shooters who need fast target acquisition without sacrificing durability or optical quality. Designed for rifles, carbines, and shotguns, this low-mount red dot lets you keep both eyes open for maximum situational awareness—whether you're hunting, running drills at the range, or working from unconventional positions. The large 25mm objective and tapered light path pack serious viewing area into a tiny footprint, so you get the speed of a non-magnified sight without tunnel vision.

The MRO HD features a 2 MOA red dot center reticle surrounded by a 68 MOA segmented circle, optimized for pairing with magnifiers or standing alone for close-to-medium engagements. You can toggle between the full reticle and center dot only using the ambidextrous brightness controls—handy when you're switching setups or adapting to changing light. Sixteen illumination settings and infinite eye relief mean you'll find a comfortable sight picture whether you're shooting in bright daylight or low light. The housing is forged 7075-T6 aluminum with a matte black finish, sealed to 100 feet of submersion, and rated to handle temperatures from –60°F to +160°F, so it'll survive anything from desert heat to mountain cold.

Battery life is realistic: the CR2032 cell runs roughly 2.5 years on the dot-only day setting, or about 75 days if you keep the full segmented reticle illuminated. The low mount sits the dot lower on your bore axis for co-witness with irons or lower scope rings if you decide to upgrade to magnification later. Sub-flush adjustment turrets and advanced lens coatings round out a sight that prioritizes ruggedness and speed over complexity.

Frequently Asked Questions

Can I use the MRO HD with a magnifier?

Yes—the MRO HD's reticle and optical design are optimized for magnifier use. The 2 MOA center dot and 68 MOA segmented circle work well when magnified, and the low mount allows room for magnifier mounting behind it.

What's the difference between the full reticle and center dot modes?

You can toggle between illuminating the entire 68 MOA segmented circle with the 2 MOA center dot, or just the 2 MOA dot alone. This flexibility lets you adapt to your shooting style or switch between setups without changing the sight itself.

How long does a battery really last?

On the center dot only (day setting 3), a CR2032 will run about 2.5 years with normal use at 70°F. If you run the full segmented reticle at day setting 3, expect roughly 75 days of continuous use before the battery is depleted. Actual runtime varies with temperature and brightness setting.

Will this sight work on a shotgun or pistol-caliber rifle?

The MRO HD is designed for rifles, carbines, and shotguns. It mounts via the low-mount base and will co-witness with standard rifle irons. Pistol mounting is not specified in the product specs, so confirm compatibility with your specific platform before purchase.
