Solar Failsafe™

Solar Failsafe Technology is one of many innovations featured on solar-equipped Holosun optics. With Solar Failsafe, if your battery fails you always have a backup power source when natural or artificial light is available. Solar Failsafe is activated while in Auto Mode where reticle intensity is automatically adjusted based on the amount of light the solar cell receives. In brighter conditions you have a brighter reticle and in lower-light conditions the reticle will step down in intensity to match any lighting conditions. On models equipped with a super capacitor, it is possible to run the optic, indefinitely, in daytime and night conditions, by maintaining a charge through the Solar Failsafe System all without a battery.

ENVIRONMENT SPECS

The Holosun HE 510C Green Dot Multi Reticle Reflex Optic Sight HE-510C-GR is a high-performance open reflex optic designed to deliver fast target acquisition, rugged durability, and advanced sighting technology for modern rifles and carbines. Built for use on AR-platform rifles, PCCs, and shotguns, this optic combines a wide viewing window with Holosun’s innovative features to provide dependable performance in both tactical and sporting applications.

At the heart of the HE-510C-GR is Holosun’s Multi-Reticle System (MRS), which allows shooters to switch between three reticle configurations: a 2 MOA green dot, a 65 MOA circle, or a combined circle-dot reticle. This flexibility allows users to adapt their sight picture depending on the shooting situation. The large outer circle is ideal for rapid target acquisition at close range, while the precise 2 MOA dot allows for accurate shot placement at extended distances.

The optic features a high-visibility green LED reticle, which many shooters find easier for the eye to pick up quickly in bright daylight conditions. This improved visibility helps shooters track targets faster and maintain a clear aiming point during rapid firing sequences.

Holosun’s Solar Failsafe™ technology provides an additional power source using ambient light. When in Auto Mode, the optic automatically adjusts brightness to match lighting conditions, ensuring optimal reticle visibility throughout the day. Combined with Holosun’s efficient LED system, the HE-510C-GR delivers up to 50,000 hours of battery life using a CR2032 battery.

Durability is another key feature of the Holosun HE 510C Green Dot. The optic is constructed with a strong aluminum housing and protective titanium hood, designed to withstand recoil, impacts, and demanding environments. The sight is also rated IP67 waterproof, making it resistant to dust and moisture in harsh conditions.

Additional features such as Shake Awake™ motion activation, 12 brightness settings including night vision compatibility, and a quick-detach Picatinny mount make the optic easy to use and adaptable to a wide range of rifle setups.

With its large viewing window, advanced reticle system, and rugged construction, the Holosun HE 510C Green Dot Multi Reticle Reflex Optic Sight HE-510C-GR is an excellent choice for shooters seeking a reliable optic that balances speed, precision, and modern innovation.
