The Holosun HS512C Circle Dot Solar QD Mount is built for shooters who demand absolute reliability, fast target acquisition, and rugged performance in any environment. Designed specifically for rifle and carbine applications, this enclosed reflex sight combines advanced solar technology, intelligent power management, and Holosun’s proven Multi-Reticle System to deliver a high-performance optic that’s ready for hard use right out of the box.
At the core of the HS512C is Holosun’s exclusive Solar Failsafe Technology, a feature that sets this optic apart from the competition. Integrated solar panels continuously supplement battery power while also providing a backup power source if the battery fails. This system automatically adjusts reticle brightness based on ambient light conditions, ensuring optimal visibility without constant manual adjustments. Paired with an included CR2032 battery, the HS512C delivers up to an impressive 50,000 hours of battery life on setting 6, giving you years of dependable operation.
The optic features Holosun’s versatile Multi-Reticle System, allowing shooters to switch between a precise 2 MOA dot, a rapid-acquisition 65 MOA circle, or the combined circle-dot reticle. The circle-dot configuration offers lightning-fast sight acquisition for close-range engagements while maintaining pinpoint precision for longer shots. For more deliberate shooting, the 2 MOA dot-only setting provides a clean and exact aiming point.
Built with a completely enclosed design, the HS512C offers enhanced protection against dirt, debris, moisture, and harsh environmental conditions. This rugged construction ensures the optic remains functional when conditions become unpredictable, making it a dependable choice for tactical applications, home defense, range use, or demanding outdoor environments.
Its multilayer reflective glass delivers a crisp, clear sight picture while maximizing light transmission for excellent visibility across lighting conditions. The parallax-free design and unlimited eye relief allow for fast, natural target engagement from virtually any shooting position.
Holosun’s Shake Awake Technology keeps the optic instantly ready by activating at the slightest movement and powering down during inactivity to preserve battery life. This intelligent feature means your optic is always prepared when it matters most.
The included absolute co-witness quick-detach mount offers secure attachment and rapid removal when needed, while the package also includes a T10 L key for installation, a lens cloth for maintenance, and a user manual for setup guidance.
With 12 brightness settings, including 10 daylight and 2 night vision compatible options, the HS512C adapts to virtually any shooting environment.
For shooters looking for an enclosed reflex sight that combines cutting-edge innovation, battle-ready durability, and uncompromising performance, the Holosun HS512C is built to exceed expectations every time you shoulder your rifle. Order it today from SMKW!
