Made as a collaboration between HOLOSUN Optics and Primary Arms Optics, the green-illuminated HE507K-GR-X2 and the red-illuminated HS507K-X2 with ACSS Vulcan Dot Reticle brings the revolutionary Vulcan aiming system to a micro reflex footprint. Designed for concealed carry, the HE507K-GR-X2-ACSS and HS507K-X2-ACSS are 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/green-illuminated brightness settings and intuitive push-button controls, the HE507K-GR-X2-ACSS and HS507K-X2-ACSS works in any lighting condition and is even compatible with night vision devices. This co-branded optic features the ACSS Vulcan Dot reticle system, which improves acquisition and recovery speed through its patented outer reference circle. When aimed on-target, the ACSS Vulcan Dot reticle appears as a simple, unobtrusive 3 MOA dot. When your aim is off target, the edge of the 230 MOA outer circle guides you back to center. ACSS Vulcan Dot alleviates one of the main weaknesses of micro reflex optics, ensuring you can always find your reticle aiming point, despite the smaller optical aperture. For many, green reticle illumination appears brighter and sharper than red reticles, improving acquisition speed. For RED illumination, the HS507K-X2-ACSS offers the same features but with a red LED emitter. The HE507K-GR-X2 with ACSS Vulcan Dot Reticle features an RMSc footprint and is natively compatible with many of the most popular concealed carry pistols.
