Holosun AEMS-CORE-X2-GR Red Dot Sight

Built for shooters who need fast target acquisition without bulk, the HOLOSUN AEMS-CORE-X2-GR delivers a wide, open sight picture in a compact closed-emitter reflex optic. The 22×28 mm window keeps your view unobstructed for both-eyes-open shooting, while Holosun’s advanced optical design reduces parallax by up to 50% to help maintain point-of-aim consistency from imperfect head positions.

A crisp 2 MOA green dot (540 nm) is easier on the eyes in bright daylight and stays usable in low light with 12 brightness settings (10 day, 2 night). Shake Awake™ motion-activation helps preserve power, and the CR2032 battery provides up to 50,000 hours of runtime—ideal for duty rifles and ready-to-go carbines. Precise 0.5 MOA clicks with a ±50 MOA adjustment range make zeroing straightforward, and the included 1.63" lower 1/3 co-witness mount integrates cleanly with AR-height iron sights.

This Holosun AEMS green dot sight is engineered for dynamic shooting, close-range hunting, and tactical applications where speed and reliability matter. With an IP67-rated housing, 7075-T6 aluminum construction, and 1000G recoil rating, it’s built to stay on zero in harsh field conditions.
