Carry in confidence and strike with precision using the Holosun® HS407CO-X2 Open Reflex Red Sight – 8 MOA Circle. Specifically designed for optics-ready pistol applications, this parallax-free reflex sight features an 8 MOA ring reticle with 12 user-selectable brightness settings (10 daylight; 2 night vision) for reliable clarity and intuitive target acquisition in any light condition. The 7076 T6 aluminum housing delivers lasting shockproof performance and dependable corrosion resistance. Shake Awake™ technology automatically activates the reticle when it detects motion for instant, hands-free activation, and automatically powers down the unit when the weapon is idle, and Solar Failsafe™ technology harnesses the sun’s energy to power the unit in daylight environments, conserving precious battery life for overcast or low-light conditions. Multilayer reflective glass lenses deflect stray light away from your eye for exceptional clarity and reduced eye fatigue. Better yet, the HE407CO-X2 delivers an impressive 50,000-hour battery life on a single CR1632 battery (included). IP67 waterproof.
