The Holosun HS510C-FDE is a rugged, open reflex red dot sight designed for rifles and carbines, now available in a Flat Dark Earth (FDE) finish for enhanced aesthetics and build matching. Featuring Holosun’s Multi-Reticle System (MRS), users can switch between a 2 MOA dot, 65 MOA circle, or circle-dot combination, allowing for fast target acquisition or precision aiming depending on your needs.

Built with a durable aluminum housing and reinforced with a titanium hood, the HS510C-FDE is engineered to withstand demanding conditions while maintaining a lightweight profile. The large viewing window provides an expansive field of view, making it ideal for rapid engagement and situational awareness.

The optic utilizes Solar Failsafe™ technology with battery backup, ensuring consistent performance in varying lighting conditions. Combined with Shake Awake™ technology, the sight automatically powers on with motion and shuts off when idle to extend battery life.

The included quick-detach (QD) mount and lower 1/3 co-witness riser make installation simple and ensure compatibility with most AR-platform rifles.
