Holosun HS510C Quick Detach Red Dot Sight w/ Picatinny Mount
The Holosun HS510C Quick Detach Red Dot Sight with Picatinny Mount is a powerhouse optic engineered for long gun applications. Crafted with versatility in mind, the HS510C seamlessly integrates with carbines, PCCs, and shotguns, boasting a rugged design that can withstand rigorous use. Its robust aluminum housing, fortified with a titanium hood, ensures exceptional shock resilience, making it a reliable companion in any scenario.
At the heart of the HS510C lies a wealth of innovative features from Holosun, setting it apart from the competition. With Solar Failsafe technology, you're never left in the dark – even if your battery fails. Harnessing natural or artificial light, Solar Failsafe activates in Auto Mode, adjusting reticle intensity based on ambient light conditions. Paired with a super capacitor, this technology enables indefinite operation, day or night, without reliance on batteries.
Enhancing battery longevity, Shake Awake Technology conserves power by deactivating the LED during periods of inactivity, while promptly reactivating with the slightest touch. This ensures seamless operation during duty or concealed carry, with customizable settings ranging from 10 minutes to 12 hours.
Equipped with the Multi-Reticle System (MRS), the HS510C offers versatile aiming solutions, featuring a Circle Dot, 2 MOA Dot, and 65 MOA Circle. With an impressive battery life of up to 50,000 hours on setting 6, and 12 brightness settings – 10 for daylight and 2 for night vision compatibility – you're equipped for extended use in varying lighting conditions.
In the box, you'll find the HS510C accompanied by an Absolute Cowitness QD Mount for swift attachment, a T10 L Key for adjustments, a user manual for comprehensive guidance, a CR2032 battery for immediate use, and a lens cloth for maintenance.
With optical specs including parallax-free operation, unlimited eye relief, and multi-coatings for enhanced clarity, the HS510C delivers precision and reliability. Its compact design, measuring 3.3x1.68x1.78 inches and weighing just 4.94 ounces, ensures minimal added bulk to your firearm.
Designed to withstand harsh environments, the HS510C boasts IP67 submersion rating, withstanding water ingress up to 1 meter for 30 minutes, along with exceptional vibration resistance up to 1000G. Whether in extreme temperatures or adverse conditions, the HS510C remains unfazed, delivering consistent performance when it matters most.

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 Awakeâ„¢
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.
