Fast Target Acquisition Every Time. 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. It is designed to be used with both eyes open, providing the operator with maximum situational awareness.
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.
Combat-Ready Out of the Box
The MRO Patrol reflex sight adds to the legendary dependability of the MRO. It includes lens covers for both the ocular and objective lenses, along with an Anti-Reflection Device KILLFLASH® that protects you from unwanted detection or in bright conditions while eliminating glare.
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.
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.
