Designed as a part of a collaboration between Holosun and Primary Arms, the Holosun HS507k-X2-ACSS Pistol Dot Sight features an ACSS Vulcan Dot Reticle that incorporates the Vulcan aiming system in the micro reflex footprint. Designed for concealed carry, the HS507K-X2-ACSS w/ ACSS Vulcan Dot Reticle is lightweight, durable, and dependable, with up to a 40,000-hour runtime on medium settings. The Holosun HS507K-X2-ACSS Pistol Dot w/ ACSS Vulcan Dot Reticle retains all the core features and technologies of the standard Holosun model, 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.

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. The HS507K-X2 with ACSS Vulcan Dot Reticle features an RMSc footprint and is natively compatible with many of the most popular concealed carry pistols.
