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. Advanced lens coatings and electronics produce a crisp red dot. The brightness control dial on the MRO is specifically designed for ambidextrous usage. Its hard-anodized, forged 7075-T6 housing is fully sealed and waterproof, providing durability in demanding conditions. The MRO Patrol includes an ocular lens cover to protect glass from damage and to reduce glare and reflections as well as an objective cover and ARD, as well as a MIL-SPEC rated 1/3 Co-Witness quick release mount with return to zero accuracy.
