Made as a collaboration between Holosun Optics and Primary Arms Optics, the 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 HS507K-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.

Available Reticles

ACSS Vulcan Dot – Segmented Circle

The patented ACSS® Vulcan® Dot reticle system improves target acquisition and recovery speed through its AutoAim™ functionality. When aimed on-target, the ACSS Vulcan Dot reticle appears as a simple, unobtrusive 3 MOA dot (4 MOA with HTX). When your aim is off-target, the edge of the 230 MOA (240 MOA with HTX) 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.
