The Holosun 507K ACSS is an amazing 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.

  • Green-Illuminated ACSS® Vulcan® Dot Reticle System
  • Ultra-compact size for concealed carry applications.
  • Two Reticle Settings: Dot + Circle, and Dot only
  • Shake Awake™ - Motion on with last setting recall.
  • Parallax-free, unlimited eye relief.
  • CNC milled 7075 Aluminum Housing.
  • 10 daylight and 2 night vision compatible brightness settings.
  • IP67 Certified.

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 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.
