The Holosun HE510C-GR is a rugged, open reflex green dot sight designed for rifles and carbines, delivering fast target acquisition and versatile reticle options. Featuring Holosun’s Multi-Reticle System (MRS), users can switch between a 2 MOA dot, 65 MOA circle, or circle-dot combination, allowing you to adapt for speed, precision, or close-quarters shooting.

The green reticle provides enhanced visibility in bright conditions and for users who prefer a sharper, more defined aiming point compared to traditional red dots.

Built for durability, the HE510C-GR features a lightweight aluminum housing with a titanium hood for added protection. The optic utilizes Solar Failsafe™ technology with battery backup, ensuring consistent operation across varying lighting environments.

Equipped with Shake Awake™ technology, the optic automatically powers on with movement and shuts off when idle to preserve battery life. The included quick-detach (QD) mount and lower 1/3 co-witness riser make installation simple and compatible with most AR-platform rifles.

Designed for real-world use, the HE510C-GR is ideal for tactical applications, range shooting, and defensive setups where speed and reliability matter most.
