The Trijicon Miniature Rifle Optic (MRO®) is a reflex-style sealed sight intended for use on rifles carbines and shotguns to provide fast target acquisition. It is designed to be used with both eyes open providing the operator with maximum situational awareness. The large aperture and tapered light path maximizes the viewing area in such a small optic allowing for fast target engagement – especially from non-standard shooting positions. It also features ambidextrous brightness controls sub-flush adjusters advanced lens coatings and a fully sealed waterproof hard anodized forged 7075-T6 housing making the MRO the ultimate mini reflex sight.

The MRO HD is optimized for use with a magnifier with a re-engineered objective lens to produce a refined 2.0 MOA center dot surrounded by a 68 MOA segmented circle reticle. The ambidextrous reticle and brightness control allows the user to choose between a full reticle or center dot only.

The Trijicon MRO (Miniature Rifle Optic) is a sealed miniature reflex sight intended for use on rifles carbines and shotguns to provide fast target acquisition.

The large aperture and tapered light path maximize the viewing area and allow for better situational awareness and fast target engagement – especially from non-standard shooting positions you might encounter while hunting or in military or law enforcement fields. Combine all this with the ambidextrous brightness controls sub-flush adjusters advanced lens coatings and the fully sealed waterproof hard-anodized forged 7075-T6 housing and you have the ultimate mini reflex sight on the market.

FASTER TARGET ACQUISITION

Larger viewing area allows for faster acquisition and engagement with reduced "tube effect."

AMBIDEXTROUS BRIGHTNESS CONTROL

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

EASILY ADJUSTABLE BRIGHTNESS SETTINGS

MRO models feature 8 brightness settings including 2 night vision-compatible settings. MRO HD models feature16 brightness settings including 4 night vision-compatible settings.

BUILT TO HANDLE THE WORST

Designed with forged 7075 housing fully sealed construction and dry nitrogen to protect against the tough elements.

RECESSED ADJUSTERS

Capless design (utilizing sub-flush adjusters) eliminates lost caps snag hazards and ensures against inadvertent adjustment or loss of zero.

SUPERIOR QUALITY GLASS LENSES

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