The Trijicon MRO HD 1x25 Red Dot Sight with 3x Magnifier (SKU MRO-C-2200057) is a matched two-part package: the Trijicon MRO HD 1x non-magnifying 25 mm red dot sight with a switchable 68 MOA segmented circle and 2.0 MOA centre dot reticle, plus a Trijicon 3x magnifier on a quick-detach flip-to-side mount and a full co-witness mount (AC32068) for the dot.
Bought together, the two optics are designed to work as one sight. The MRO HD objective lens is re-engineered specifically to be looked through by a magnifier, which is what stops the dot smearing or the image going soft when the magnifier swings in behind it. Flip the magnifier out of the way and you have a 1x dot for close work; flip it in and you have 3x magnification for identifying and holding on a target at distance.
Trijicon builds the MRO — Miniature Rifle Optic — to duty standard: sub-flush adjusters that cannot be knocked off zero in a slip, and a body sealed waterproof to 100 ft (30 m) and fogproof. That heritage is engineering, not marketing.
How It Compares
This is the fixed-mount version of the combination. If you want a quick-release Q-LOC mount instead, the MRO HD Patrol and 3x magnifier combination (MRO-C-2200111) is the same idea on Trijicon's lever mount, and the MRO SD Patrol and 3x magnifier combination (MRO-C-2200368) swaps the circle-dot reticle for a plain 2.0 MOA dot. For the dot on its own, see the Trijicon MRO HD red dot sight in its four mounting configurations, or the simpler Trijicon MRO SD red dot sight. To choose a magnifier separately, browse the red dot sight magnifiers, and for a magnified optic without a separate dot, the prism scope range. Browse the Trijicon rifle red dot sights and the optics for straight-pull rifles, or read our guide to choosing a red dot magnifier and Trijicon buyer's guide.
Ideal For
- Civilian Service Rifle and practical rifle shooting on a straight-pull AR-pattern rifle, where one stage mixes close targets with 200 m and 300 m detail
- Practical shotgun and 3-Gun, flipping the magnifier out of the way for close stages and back in for the long one
- Night fox and vermin control, using the night-vision compatible brightness settings and the magnifier to confirm the target
- Shooters who want one optic set-up rather than swapping between a dot and a scope

Frequently Asked Questions
Does this package include both the red dot sight and the magnifier?
Yes — MRO-C-2200057 supplies the Trijicon MRO HD 1x25 red dot sight, a Trijicon 3x magnifier, a quick-release flip-to-side mount for the magnifier and a full co-witness mount (AC32068) for the dot, so no separate mount purchase is needed.
Why buy the MRO HD rather than any red dot behind a magnifier?
The Trijicon MRO HD uses an objective lens re-engineered specifically for use behind a magnifier, which is why Trijicon packages the two together. Our guide to choosing a red dot magnifier explains why not every dot behaves well at magnification.
What battery does the Trijicon MRO HD use?
The Trijicon MRO HD runs on a single CR2032 coin cell, with up to around 2.5 years of run time on the dot-only setting. The magnifier is a purely optical device and needs no power at all.
How big is the 68 MOA circle at 100 yards?
A 68 MOA circle subtends about 71 in (1.8 m) at 100 yards, and the 2.0 MOA centre dot about 2.1 in (53 mm), so the circle frames a target while the dot marks the aiming point.
What is the field of view through the magnifier?
The magnifier gives a 7.2 degree field of view, which is 37.5 ft at 100 yards (12.5 m at 100 m).
Is the Trijicon MRO HD waterproof?
Yes — the Trijicon MRO HD is sealed waterproof to 100 ft (30 m) and fogproof, which is why it is specified for hard outdoor use in British weather.
