Designed for sporting rifle and carbine applications, the Holosun HE403C Green 2 MOA Dot Sight is a feature-rich platform, favored by competition shooters, casual plinkers, target shooters, and law enforcement professionals alike. Equipped with an ultradurable 6061 T6 aluminum housing, this parallax-free Holosun optic offers lasting performance in demanding environments. Powered by a Holosun Super LED bulb, the 2 MOA illuminated green dot reticle delivers quick, intuitive target acquisition, while 12 user-selectable brightness settings (10 daylight; 2 night vision) ensure optimal visibility in any lighting. 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 HE403C delivers an impressive battery life of up to 50,000 hours on a single CR1632 battery (included). IP67 waterproof.
