Holosun HE507C-GR-X2 Green Dot Reflex Sight - Primary Arms ACSS Vulcan

The Holosun HE507C-GR-X2 is an open reflex pistol optic built around the proven HE507C housing and configured with Primary Arms' ACSS Vulcan green reticle. Designed for use on full-size and compact pistols with an RMR-pattern footprint, it pairs a crisp green LED chevron with a fast-pickup 10 MOA outer ring for rapid target acquisition at speed.

The HE507C-GR-X2 runs on a single CR1632 battery and is rated for up to 20,000 hours of runtime on setting 6. Holosun's Solar Fail Safe backup draws supplemental power from the top-mounted solar cell, while Shake Awake motion-activation puts the optic to sleep at rest and instantly powers it back on at the slightest movement.

The streamlined housing keeps the optic low-profile on the slide for co-witnessing with standard iron sights. The ACSS Vulcan reticle layout uses the chevron as the primary aiming point with the 10 MOA outer circle for fast close-range indexing, making this configuration well suited to both defensive and competition use.
