The Holosun AEMS CORE X2 green dot sight is the streamlined, value-focused member of the enclosed AEMS rifle line — a clean 2 MOA green dot in a sealed, large-window housing. Green is perceived as brighter by many shooters, helping the dot pop against varied backgrounds.
The X2 optical system reduces parallax by up to 50% for tighter accuracy, and Shake Awake keeps it ready with up to 50,000 hours of runtime. It ships on a lower-1/3 co-witness mount, ready for AR-pattern rifles.
