The Holosun AEMS-PRO-X2 is an enclosed rifle sight with an improved optical system designed to reduce parallax while maintaining a wide viewing window. It features a Multi-Reticle System with selectable 2 MOA dot, 65 MOA circle, or combined circle-dot reticle options, along with Solar Failsafe, Shake Awake, automatic and manual brightness adjustment, Memory, and Lockout Mode. A forward-facing light sensor automatically adjusts reticle intensity, while the side-loading CR2032 battery tray allows battery replacement without removing the optic. The sight includes a four-post lower 1/3 co-witness mount and integrated anti-reflective device.
