The Holosun 509 is a fully enclosed pistol red dot sight that comes with the ACSS Vulcan Reticle designed to improve speed and accuracy. The revolutionary patented 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.
Note: The 509 ACSS model does not share the same footprint as the 509T (non-ACSS models) and therefore is incompatible with aftermarket mounting solutions and custom cut slides for the 509T (non-ACSS models).
