The Holosun HS510C HUD Circle Dot Sight delivers advanced performance with a wide field of view, lightweight construction, and multiple reticle options. Powered by both a CR2032 battery and Holosun’s Solar Failsafe technology, this optic provides up to 50,000 hours of operation while automatically adjusting brightness to match ambient light. The Shake Awake feature conserves power by placing the sight into sleep mode when idle, then instantly reactivates it with movement. Users can select between three reticle configurations—a 65 MOA circle with 2 MOA dot, 2 MOA dot only, or 65 MOA circle only—making it adaptable for precision or rapid target acquisition. Compact, reliable, and packed with features, the HS510C Holosun red dot sight is an ideal choice for rifles and carbines.
