The Trijicon MRO(R) (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 allows for better situational awareness and fast target engagement-especially from non-standard shooting positions.
