The Holosun HS510C is a rugged open reflex rifle optic engineered for carbines, PCCs, shotguns, and tactical rifle platforms. Designed for rapid target acquisition and versatile performance, the HS510C combines a large viewing window, advanced electronics, and durable construction into one of the most trusted open reflex optics available.
At the core of the optic is Holosun’s advanced Red Multi-Reticle System (MRS), allowing shooters to quickly select between a precise 2 MOA red dot, a fast-acquisition 65 MOA circle, or a combined circle-dot reticle. This adaptable system gives shooters the flexibility to optimize the optic for close-quarters speed, defensive shooting, or precision engagements at extended distances.
The HS510C also incorporates Holosun’s innovative Solar Failsafe Technology, utilizing an integrated solar panel to supplement battery power and assist with automatic brightness adjustment in changing lighting conditions. This system enhances reliability while helping maximize overall battery efficiency during prolonged use.
For fast installation and dependable mounting performance, the optic includes an integrated Quick Detach Co-Witness Mount designed for direct attachment to standard Picatinny rails. The QD system allows rapid optic removal or installation while maintaining reliable return-to-zero performance, making it ideal for defensive, duty, and competition applications.
One of the standout features of the HS510C is its oversized Open Reflex Sight Window, which provides a wide field of view for faster target acquisition, improved peripheral awareness, and smoother tracking during dynamic shooting situations. The expansive viewing area is especially beneficial for close-range engagements and rapid transitions between targets.
Holosun’s proven Shake Awake Technology automatically powers the optic on when motion is detected and powers it down during inactivity to preserve battery life. Combined with the efficient LED system, the HS510C delivers up to 50,000 hours of runtime from a single CR2032 battery.
The optic is built with a durable aluminum housing reinforced by a rugged titanium protective hood for enhanced impact resistance in harsh environments. Additional features such as the side-mounted battery tray, lockout mode, multi-coated glass, and IP67 waterproof protection make the HS510C an outstanding choice for serious shooters demanding reliability and performance.
With its combination of durability, speed, advanced reticle technology, and user-friendly features, the Holosun HS510C remains one of the most popular open reflex optics for modern rifle platforms.
