The Trijicon MRO SD Patrol 1x25 Red Dot with 3x Magnifier is a compact, sealed reflex sight designed for rifles, carbines, and shotguns to deliver rapid target acquisition with both eyes open for maximum situational awareness. It features a re-engineered objective lens for enhanced optics and magnifier compatibility, ambidextrous brightness controls, sub-flush adjusters, advanced lens coatings, and a fully sealed waterproof 7075-T6 forged aluminum housing that makes the MRO SD a durable, high-performance mini reflex sight. The sights large aperture and tapered light path maximize the viewing area for fast engagements from non-standard positions, while improved windage and elevation adjusters maintain strict zero retention under drop and recoil. The Patrol includes lens covers for both ocular and objective lenses plus an Anti-Reflection Device KillFLASH to minimize glare and protect against detection in bright conditions. The included 3x magnifier with a short, lightweight, flip-to-side quick-release mount centers the reticle in the field of view, enables quick transitions to extended-range targets, and supports 1/3 or full co-witness alignment. Together, these features provide a versatile, reliable aiming solution for dynamic shooting scenarios.
