Holosun HE507K-X2 Compact Pistol Red Dot Sight - Red ACSS® Vulcan® Dot Reticle

Holosun HE507K-X2 Compact Pistol Red Dot Sight - Red ACSS® Vulcan® Dot Reticle

Designed specifically for concealed carry and compact pistol platforms, this optic combines cutting-edge durability with the revolutionary ACSS® Vulcan® reticle system for unmatched speed and confidence under pressure.

At the heart of this optic is the red-illuminated ACSS Vulcan Dot reticle, engineered to solve one of the biggest challenges of micro red dots—finding the reticle quickly. When perfectly aligned, you see a crisp 3 MOA dot. When off-axis, a massive 230 MOA reference circle guides your eye back to center, ensuring you never lose your aiming point in high-stress situations. This AutoAimm™-inspired system dramatically improves recovery speed and accuracy, especially for defensive shooting.

Built for real-world carry, the HE507K-GR-X2-ACSS is ultra-compact, lightweight, and rugged enough for daily use. With up to 40,000 hours of battery life, Shake Awake™ technology, and multiple brightness settings—including night vision compatibility—it’s always ready when you need it. Whether you're upgrading your EDC pistol or building a defensive setup, this optic delivers precision, speed, and reliability in one compact package.
