Holosun HS503CU Red Dot Sight

Optimized for use with sporting rifles and carbines, the Holosun® HS503CU Red Dot Sight comes equipped with a low-profile, 1/3 co-witness mount, coupled with a durable 6061 T6 aluminum housing, perfect for tactical environments. Featuring Holosun’s Multi-Reticle System, this versatile red dot allows you to choose your favored reticle (2 MOA dot, or 2 MOA dot with a 65 MOA circle) for enhanced reliability, while 12 brightness settings (10 daylight; 2 night vision) deliver exceptional clarity in any lighting. Shake Awake™ technology automatically activates the red dot when it detects motion for instant, hands-free activation, and automatically powers down the unit when the weapon is idle. Solar Failsafe™ technology harnesses the sun’s energy to power the unit in daylight environments, conserving 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. Operating on a single CR2032 battery (included), the HS503CU offers an impressive 50,000-hour battery life (lowest setting). IP67 waterproof.
