Drop targets in confidence with the Holosun® AEMS CORE Red Dot Sight from GunMag Warehouse. Specifically designed for rail-equipped rifle and carbine applications, this parallax-free reflex sight features Holosun’s proprietary Multi-Reticle System, this versatile red dot allows you to choose your favored reticle (Circle dot, 2 MOA dot, or 65 MOA circle) for enhanced reliability, while 12 user-selectable brightness settings (10 daylight; 2 night vision) deliver exceptional clarity 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. Multilayer reflective glass lenses deflect stray light away from your eye for exceptional clarity and reduced eye fatigue. Better yet, the 7076 T6 aluminum housing delivers lasting shock and corrosion resistance for reliable field performance. Operates on one CR2032 battery (included). 50,000-hour battery life. Includes flip-up lens covers. IPX8 waterproof.
