The Trijicon MRO SD Patrol 1x25 Red Dot Full Mount is a compact, reflex-style sight designed for rifles, carbines, and shotguns, delivering fast target acquisition with both eyes open to maximize situational awareness. Its large aperture and tapered light path maximize the viewing area in a small optic, enabling rapid engagement from non-standard shooting positions, while ambidextrous brightness controls, sub-flush adjusters, advanced lens coatings, and a fully sealed, waterproof 7075-T6 forged aluminum housing maintain rugged reliability in demanding field conditions. The MRO SD re-engineered objective lens enhances optical performance and magnifier compatibility, and improved windage and elevation adjusters help maintain strict zero retention under recoil and drop. The Patrol version includes lens covers for the ocular and objective, along with an Anti-Reflection Device KILLFLASH to reduce glare and protect from detection in bright environments. This sight uses a 2.0 MOA red dot with 8 illumination settings powered by a single CR2032 battery, offering up to 2.5 years of life at day setting 3, and features a full co-witness Quick Release Mount, 25 mm objective, 4.35 x 1.7 x 2.0 inches footprint, and a 5.0 oz weight for predictable, durable performance.
