Holosun HS507K-X2 ACSS Vulcan Red Micro Reflex Sight for Concealed Carry

The Holosun HS507K-X2 ACSS Vulcan Red is a precision-engineered micro reflex sight developed through a collaboration between Holosun Optics and Primary Arms Optics. Featuring the patented ACSS Vulcan Dot Reticle, this compact optic brings an advanced aiming system to a micro reflex footprint — purpose-built for concealed carry pistols and subcompact handguns.

Built to perform in real-world conditions, the HS507K-X2 ACSS delivers up to 40,000 hours of runtime on medium brightness settings, ensuring your optic is always ready when you need it most. The Multi-Reticle System gives shooters the flexibility to select their preferred aiming point, while Shake Awake technology automatically activates the sight upon movement and powers down during periods of inactivity to conserve battery life. A built-in Lock Mode prevents accidental adjustments during carry or storage.

With 12 red-illuminated brightness settings and intuitive push-button controls, this sight adapts seamlessly to any lighting environment — from bright daylight to low-light scenarios — and is fully compatible with night-vision devices for enhanced low-light capability.

Lightweight and durable, the HS507K-X2 ACSS Vulcan Red is an ideal upgrade for everyday carry, home defense, or duty use. Whether you’re a seasoned shooter or building your first carry setup, this optic delivers the reliability and performance you can trust.
