The Holosun HE509T-RD-X2-FDE is a durable enclosed miniature reflex sight engineered for pistols and compatible carbine platforms requiring reliable performance and rapid target acquisition. Constructed with a lightweight titanium housing and finished in Flat Dark Earth, this optic delivers exceptional strength and environmental protection. It features Holosun’s red Multi-Reticle System, allowing users to select between a precise 2 MOA dot, a 32 MOA circle, or a circle-dot combination to suit various shooting scenarios. Solar Failsafe technology supplements battery power in bright lighting conditions, while Shake Awake automatically activates the reticle when movement is detected to maximize battery efficiency. The enclosed emitter design protects internal components from moisture, debris, and harsh environmental conditions, ensuring consistent performance in tactical, defensive, and competition applications.
