Holosun HS510C Open Reflex Red Dot Sight 2 MOA/65 MOA Circle

The Holosun HS510C delivers precision targeting with its dual reticle system combining a crisp 2 MOA dot with a 65 MOA circle for rapid target acquisition. This open reflex sight eliminates the tunnel vision common with tube-style optics while maintaining exceptional battery life through Holosun's Solar Failsafe technology.

What Makes This Different

Unlike traditional red dots that rely solely on battery power, the HS510C incorporates both solar and battery power systems for uninterrupted operation. The open design provides unlimited eye relief and a wider field of view compared to enclosed tube sights. Holosun's Shake Awake technology automatically powers the unit on with movement and shuts off during periods of inactivity, extending the CR2032 battery life to 50,000 hours.
