The Holosun HE508T X2 Red Dot Sight is a premium open-reflex pistol red dot sight built from Grade 5 titanium for maximum strength in a compact body. Its Multi-Reticle System switches between a 2 MOA dot, a 32 MOA circle, or circle-dot, with a generous 23 × 16 mm window and the widely supported RMR footprint.
The X2 revision adds Lock Mode, alongside Solar Failsafe and Shake Awake for dependable runtime in any lighting. CR1632 power, IP67-rated.
