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 Trijicon MRO with green dot continues the legendary dependability of the MRO, featuring an adjustable 2.0 MOA green dot and exceptional lens clarity with a reticle that has a greater contrast against forest, grassland and tropical environments. This is because the human eye is more sensitive to this green color, making this MRO especially effective for fast target acquisition in low light and transitional lighting conditions.
