Holosun 510C

Open Reflex Sight for Rifles and Carbines

The Holosun 510C is an open-reflex sight built for rifle and carbine applications, offering exceptional clarity, durability, and adaptability. Featuring 12 brightness settings and up to 50,000 hours of battery life, the 510C delivers dependable performance in all lighting conditions. It is submersible to 1 meter and equipped with Holosun’s Solar Failsafe, Shake Awake, and Multiple Reticle System (MRS) technologies for maximum versatility and reliability.

Multiple Reticle System (MRS)

The MRS provides the option of a 2 MOA dot, a 65 MOA circle, or a 2 MOA/65 MOA circle-dot reticle for fast target acquisition or precision shooting. All reticle versions are projected from the same LED, so no re-zeroing is required when switching modes. The optic is available in both red and green reticle variants, allowing shooters to match their visual preference and environment.

Performance and Durability

Constructed with a robust aluminum and titanium hood design, the 510C offers long-term resilience under field conditions. Holosun’s multilayer reflective glass provides a bright, crisp sight picture with true color transmission. The parallax-free design and unlimited eye relief allow for rapid, natural target alignment during fast-paced shooting.

Power Efficiency and Control

The Shake Awake feature automatically powers the sight on and off based on motion, preserving battery life while ensuring instant readiness. The last setting recall function retains brightness and reticle preferences between uses.
