The Holosun HE508T X2 Green Dot Sight is a premium open-reflex pistol optic built around a Grade 5 titanium housing for exceptional strength in a compact footprint, with a high-visibility green reticle. The Multi-Reticle System gives a 2 MOA dot, 32 MOA circle or circle-dot.
The X2 revision adds Lock Mode to prevent accidental adjustments, plus Solar Failsafe and Shake Awake for extended runtime. Built on the RMR footprint.
