The red-illuminated HS507K-X2 with patented ACSS® Vulcan® Dot Reticle brings the revolutionary Vulcan aiming system to a micro reflex footprint. Designed for concealed carry the HS507K-X2-ACSS is lightweight durable and dependable with up to a 40 000-hour runtime on medium settings. This sight retains all the core features and technologies of the standard Holosun model including the Multi-Reticle System Shake Awake technology and a built-in Lock Mode. With 12 red-illuminated brightness settings and intuitive push-button controls the HS507K-X2-ACSS works in any lighting condition and is even compatible with night vision devices. The ACSS Vulcan Reticle is a revolutionary approach to reflex sights giving the optic AutoAim™ functionality by improving user agility through a ‘heads-up’ target acquisition. Under duress standard reflex reticles can be lost without proper sight alignment. With the ACSS Vulcan reticle users always know the relative location of their aiming point allowing for quick correction and improved accuracy on target.
