Trijicon MRO HD Sights

Trijicon MRO HD Sights

Explore Trijicon MRO HD sights with a red 2 MOA dot and an optional 68 MOA segmented circle. The HD design combines a 1x view, a 25 mm objective, and a selectable reticle in a sealed forged-aluminum housing. The range includes standalone sights, Patrol configurations, and packages with a 3x magnifier.

The main choices are the included mount, lens-protection accessories, and whether a magnifier comes in the box. These details distinguish the packages without changing the HD system’s red circle-and-dot reticle. All of the MRO HD configurations in this collection have black housings.

Choose a Mount Height

The MRO HD with low mount includes the AC32067 base for applications where a lower sight height is preferred. The full co-witness model includes the AC32068 mount, which aligns with compatible standard-height backup iron sights. The lower 1/3 co-witness model uses the AC32069 mount to place compatible iron sights lower in the window.

A no-mount version leaves the base and mounting height to your choice of compatible MRO mount. Fixed mounts and Q-LOC quick-release mounts are distinct package options. Compatibility depends on the platform and other accessories, so the mount included with the exact model matters more than a general family name.

Standard, Patrol, and Magnifier Packages

Patrol models add objective and ocular flip caps and an anti-reflection device. Mounted Patrol configurations use Q-LOC quick-release sight mounts, while the no-mount Patrol version leaves the base out. These accessories protect the lenses and help reduce front-lens reflections without changing the reticle’s dot or circle size.

The MRO HD combo with 3x magnifier, model MRO-C-2200057, includes an AC32068 full co-witness sight mount and a separate quick-release, flip-to-side magnifier mount. The magnifier adds a 3x view and has an adjustable diopter. The sight remains a 1x optic when the magnifier is out of the optical path; this is not a variable-power scope.

The MRO HD Patrol combo, model MRO-C-2200111, adds Patrol lens accessories and an AC32070 full co-witness Q-LOC sight mount alongside the 3x magnifier. Both combo packages include a magnifier riser and fasteners for compatible full or lower 1/3 co-witness heights. A standalone sight does not include a magnifier unless the package explicitly says so.

Reticle and Illumination

The MRO HD can display the center dot alone or the dot with its segmented circle. Each mode has eight brightness settings, including two night-vision-compatible settings, for 16 settings in total. The night-vision settings provide low-output illumination for compatible equipment; they do not make the sight a night-vision device.

A CR2032 battery powers the LED. Trijicon rates continuous use at up to 2.5 years for dot-only mode or 75 days for the circle-and-dot reticle at daylight setting 3 and 70 degrees Fahrenheit. Reticle mode, brightness, and temperature affect battery life. The MRO SD collection covers single-dot models, while the broader MRO collection brings the related families together.

Trijicon MRO HD FAQs

What distinguishes the MRO HD from the MRO SD?

The MRO HD offers a red 2 MOA dot with an optional 68 MOA segmented circle. MRO SD models use a single-dot reticle. The HD also provides eight brightness settings for each of its two reticle modes.

Does every MRO HD include a mount?

No. No-mount models require a compatible base purchased separately. Other packages include a low, full co-witness, or lower 1/3 co-witness mount. Mounted Patrol packages use Q-LOC quick-release sight mounts.

What comes with an MRO HD Patrol?

Patrol configurations include objective and ocular flip caps and an anti-reflection device. The exact package determines whether a sight mount or a 3x magnifier is included. The no-mount Patrol sight does not include a Q-LOC base.

Is the MRO HD a 3x optic?

The sight itself is 1x. A combo adds a separate 3x magnifier with a flip-to-side mount. Standalone MRO HD sights do not include that magnifier.

Can the circle be turned off?

Yes. The reticle control allows a dot-only view or the combined dot-and-circle view. Both modes use the same red 2 MOA center dot.

How long does the battery last?

Trijicon rates the MRO HD for up to 2.5 years of continuous dot-only use or 75 days with the circle-and-dot reticle at daylight setting 3 and 70 degrees Fahrenheit. Actual runtime varies with brightness and temperature.

Is a magnifier included with a full co-witness model?

Not necessarily. Full co-witness describes the sight mount height, not the package contents. Model MRO-C-2200052 includes a sight and mount only; model MRO-C-2200057 also includes the 3x magnifier. Separate magnifiers are listed in the Trijicon magnifier collection.
