Holosun Primary Arms 507K Green Dot Reflex ACSS Vulcan Reticle HE507K-GR-X2-ACSS

Made as a collaboration between Holosun Optics and Primary Arms Optics, the green-illuminated HE507K-GR-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 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 green-illuminated brightness settings and intuitive push-button controls, the HE507K-GR-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.

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.

This version of the optic uses GREEN reticle illumination. 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 507K-GR-X2 with ACSS Vulcan Dot Reticle features a modified RMSc footprint. While the screw slots and recoil lugs are the same, the overall dimensions of the red dot base are slightly different and may not fit some slides milled for the RMSc optic. It does mount directly to the P365X/XL slide.
