Optics Review: The Trijicon MRO w/ Green Dot

Trijicon's MRO (Miniature Rifle Optic) is a reflex-style, sealed sight intended for use on rifles, carbines, and shotguns to provide fast target acquisition.

With enhanced shooting accuracy and speed in conjunction with a larger field of view, the MRO has proven itself as one of the premiere miniature shooting optics in the world.


Designed to be used with both eyes open, the MRO provides the shooter with maximum situational awareness.

Featuring an adjustable 2.0 MOA green dot and exceptional lens clarity with a reticle that has a greater contrast against forest, grassland and tropical environments. Along with, Trijicon's advanced lens coatings and electronics, the MRO produces a crisp green dot.

A fact many may not know is that the human eye is far more sensitive to the green color, making the MRO especially effective for fast target acquisition in low light and transitional lighting conditions. The large aperture and tapered light path maximizes the viewing area in such a small optic, allowing for rapid target engagement, especially when in non-standard shooting positions.

The brightness control dial on the MRO is specifically designed for ambidextrous usage. With a mid-adjustment “off” position and eight discernible brightness settings, this brightness dial allows for quick adjustments. The MRO features fully protected adjusters that maintain zero even during rough handling, and can be adjusted without the need for special tools. In additions, the MRO's hard-anodized, forged 7075-T6 housing is fully sealed and waterproof, providing durability in demanding conditions.


  • Large viewing area allows faster target acquisition and engagement with reduced “tube effect.”

  • Brightness dial is equally usable by left or right-handed operators without having to remove hand from fire control.

  • Eight brightness settings, including two night vision-compatible settings with a mid-position “off” feature.

  • Adjusters provide positive-click reticle movement in ½-MOA increments and require no special tools for operation.

  • Forged 7075 housing and fully sealed construction protects against the toughest elements.

  • Capless design eliminates lost caps, snag hazards and ensures against inadvertent adjustment or loss of zero.

  • Multi-coated lenses provide superior clarity and light-gathering capabilities with zero distortion and provide for a crisp dot reticle.

  • Waterproof up to 45 meters (150 ft.)

  • Dry-nitrogen-filled to prevent fogging.

  • Five years of continuous use at Day Setting 3 (setting 5 of 8) at 70°F with supplied CR2032 lithium battery.
