The Holosun HE510C-GR features cutting-edge Solar Failsafe technology that ensures you're never without a point of aim, automatically adjusting reticle brightness in response to lighting conditions and providing a backup power source in the absence of battery power. The optic's Multi-Reticle System lets you swiftly toggle between a 65 MOA circle with a 2 MOA dot for rapid target acquisition or a singular 2 MOA dot for precision aiming. Shake Awake technology conserves battery life by powering down the LED during inactivity and instantly reactivates upon movement. This optic comes with an absolute co-witness QD mount and boasts a battery life of up to 50,000 hours, making it an elite choice for demanding environments.
