Details The Holosun HE507C-GR-X2-ACSS is a new generation of pistol red dot sight packed full of features like the multiple reticle system, solar failsafe, and shake awake technology to ensure your reflex sight is always operational when you need it. On top of the two battery-saving techniques, the HE507C-GR-X2 reflex sight features up to 20,000-hour battery life on setting 6 with the CR1632 battery. This battery is located in a convenient tray that slides out and allows you to easily change it without having to remove the optic from your pistol. This model features the revolutionary, patent-pending ACSS Vulcan reticle with an outer circle. It features 7075-T6 aluminum construction with an anodized black finish and fully multicoated glass for long-term durability that is backed by Holosun's limited lifetime warranty. The revolutionary patent-pending ACSS Vulcan reticle provides a large circle guiding the eyes towards the 10 MOA center chevron, eliminating one of the biggest challenges for shooters new to slide-mounted red dots. If you are off-center, a portion of this outer circle will appear in the window to give you an instant reference on how to get centered. The circle phases out of the sight window completely when the center chevron is properly aligned in the sight window. This patent-pending reticle function significantly improves sight acquisition. It takes the common frustration of hunting for the center reticle out of the equation. Don't need the circle? It can be easily deactivated to extend the battery even further.
