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 maximizes the viewing area and allows for better situational awareness and fast target engagement – especially from non-standard shooting positions.

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.

Is the Trijicon MRO waterproof? All MRO's are rated to pressures equivalent depths of 100 feet (30 meters).

Battery Life: The MRO battery should last for 5 years of continual use at setting “3” (5 of 8). When left on at the brightest setting (“6”), the battery should last around 25 days. Note that extended use in extreme temperatures – either cold or hot – may reduce the battery life considerably.

The front lens on my MRO is installed at an angle. Is this correct? Yes this is correct. The front, or objective lens is installed at a precise angle in order to reflect the red dot back to the user’s eye. This angled objective lens is common to all reflex‐style optics. It may be more noticeable on the MRO than some other optics due to the increased size of the lens.
