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.
2.0 MOA Adjustable Red Dot
The Trijicon Miniature Rifle Optic (MRO®) 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. Advanced lens coatings and electronics produce a crisp red dot. 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 and ergonomic adjustments.
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.
