The Trijicon MRO SD Patrol 1x25 Red Dot Sight is a sealed miniature reflex sight designed for rifles, carbines, and shotguns to deliver fast target acquisition with a large aperture and a tapered light path that maximize the viewing area for superior situational awareness and rapid target engagement. The re-engineered objective lens enhances optical performance and magnifier compatibility, while improved windage and elevation adjusters help maintain strict zero retention under drop and recoil. Ambidextrous brightness controls, sub-flush adjusters, advanced lens coatings, and a fully sealed, waterproof 7075-T6 forged aluminum housing combine to make this the ultimate mini reflex sight on the market. The MRO SD Patrol includes lens covers for both ocular and objective lenses and an Anti-Reflection Device KILLFLASH to protect against glare and concealment in bright conditions. With a 25mm objective, a 2.0 MOA red dot reticle, eight illumination settings, and an infinite eye relief, this sight delivers precise aiming with dependable performance across day and low-light environments. Powered by a single CR2032 battery, it offers up to 2.5 years of continuous use at day setting 3, ensuring long-term reliability in the field. Submersion depth reaches 100 feet, and the compact dimensions (4.35 in x 1.7 in x 2.0 in) and light 5.0 oz. weight make it an agile choice for versatile mounting options.
