Holosun HE510C Quick Detach Green Dot Sight w/ Picatinny Mount
The Holosun HE510C Quick Detach Green Dot Sight with Picatinny Mount is an advanced open reflex optic designed specifically for long gun applications. Its robust construction, featuring a durable aluminum housing with a titanium hood, makes it ideal for use on carbines, PCCs, and shotguns. This design ensures it can withstand rigorous conditions, providing reliability and durability for various shooting needs.
This optic includes a Quick Detach (QD) absolute co-witness mount, placing the dot at a height of 1.41 inches. For users who prefer a higher co-witness, an additional lower 1/3 co-witness spacer is available separately, raising the dot height to 1.63 inches. The HE510C-GR integrates several of Holosun’s signature technologies, such as Solar Failsafe, Shake Awake, and the Multi-Reticle System (MRS). Its Green Super LED offers a remarkable battery life of up to 50,000 hours, with 10 daylight settings and 2 settings compatible with night vision.
Solar Failsafe technology ensures a backup power source by utilizing natural or artificial light, automatically adjusting the reticle intensity based on the surrounding light conditions. Shake Awake technology conserves battery life by turning off the LED when the optic is not in use and instantly reactivates it with any motion, ensuring the sight is always ready.
The HE510C-GR offers flexible reticle options, including a 2 MOA dot, a 65 MOA circle, or a combination of both, catering to different shooting preferences. Its optical specifications include a parallax-free design and unlimited eye relief, ensuring quick target acquisition and accuracy. The sight’s compact dimensions, measuring 3.3 x 1.68 x 1.78 inches, and its lightweight design at 4.94 ounces, add minimal weight to the firearm.
Powered by a CR2032 battery housed in a convenient tray for easy replacement, the HE510C-GR is built to endure harsh environmental conditions, with an IP67 rating for water resistance and the capability to operate in temperatures from -30℃ to 60℃. It can also withstand vibrations up to 1000G, ensuring consistent performance under challenging conditions.
The package includes the HE510C-GR sight, an absolute co-witness QD mount, a T10 L key, a user manual, a CR2032 battery, and a lens cloth, providing all the essentials for immediate setup and maintenance.

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.
Shake Awake™
Shake Awake Technology is a standard feature on all current model Holosun optics and serves to extend battery life by deactivating the optic’s LED while not in use. A highly sensitive motion sensor works to detect motion keeping the LED powered on during use. This allows for duty or concealed carry with seamless operation throughout your day or shift. At the end of your day or shift when your firearm is stored, the motion sensor will detect a motionlessness state and after 10 minutes (default setting) Shake Awake Technology powers the LED off until motion is again detected. Shake Awake offers settings from 10 minutes to 12 hours depending on the model and can be deactivated altogether if preferred. The slightest touch of the optic instantly reactivates the LED so your Holosun optic is ready when needed.
