The Holosun HE509T-RD X2 is an enclosed-emitter pistol optic built around a titanium housing and Holosun's Multi-Reticle System (2 MOA dot, 32 MOA circle, or circle-dot). Solar Failsafe, Shake Awake, and a side-loading CR1632 battery tray keep the sight powered and easy to service without removing it from the slide.
