Trijicon MRO HD 1x25 Red Dot Sight - Matte Black, 68 MOA Reticle w/ 2 MOA Red Dot (No Mount)

The Trijicon MRO HD 1x25 red dot sight is a compact reflex optic built for shooters who need speed, situational awareness, and reliability in a small package. Unlike bulkier optics, the MRO HD's miniature form factor doesn't force you to choose between target focus and surroundings — the large aperture and tapered light path let you keep both eyes open, see your target and the world around you, and transition between targets fast. That matters whether you're running a carbine, shotgun, or rifle platform in the field, at the range, or in dynamic shooting scenarios.

This is the HD version, which Trijicon engineered specifically for use with magnifiers. The refined 2 MOA center dot sits inside a 68 MOA segmented circle, giving you precision for precise shots and a bigger reticle pattern for speed when you need it. Ambidextrous brightness controls and reticle selection (full circle or center dot only) mean you can dial in your preference whether you're left- or right-handed. The sealed, hard-anodized 7075-T6 aluminum housing is fully waterproof to 100 feet and rated to handle -60°F to +160°F, so weather and temperature swings won't slow you down.

Power comes from a standard CR2032 battery, with 16 illumination settings. At the typical mid-range day setting, expect 2.5 years of battery life if you run the center dot alone — long enough that you'll likely lose the optic before the battery dies. If you run the full reticle, plan on 75 days of continuous use at that same setting. The MRO HD weighs just 4.6 ounces and measures 2.9 inches long, making it one of the lightest, most compact duty-ready red dots available. Note: this version ships without a mount, so you'll need to source your own.

Frequently Asked Questions

Can I use the MRO HD with a magnifier?

Yes — the MRO HD was specifically redesigned for magnifier use. The refined 2 MOA center dot and 68 MOA segmented circle reticle are optimized to pair with quality magnifiers.

Is the MRO HD weatherproof?

Fully. The sealed, hard-anodized 7075-T6 aluminum housing is waterproof to 100 feet and operates reliably across extreme temperatures from -60°F to +160°F.

What battery does it use and how long does it last?

The MRO HD runs on a standard CR2032 battery. If you use the center dot only at a mid-range day brightness setting, expect 2.5 years of continuous battery life. Running the full reticle at the same setting yields approximately 75 days of continuous use.

Does this come with a mount?

No — this version is sold without a mount. You will need to purchase a compatible mount separately for your firearm platform.
