Primary Arms Optics Holosun HS507C-X2 ACSS Vulcan Red Dot Sight - Solar Failsafe, RMR Footprint

The Holosun HS507C-X2 is a compact pistol red dot sight featuring the Primary Arms ACSS Vulcan reticle - a distinctive chevron center paired with a 10 MOA outer ring designed for fast, intuitive target acquisition. Built on Holosun's proven 507C X2 platform and featuring Primary Arms Optics' proprietary ACSS Vulcan reticle, this optic is purpose-built for duty use, competition, and everyday carry.

The HS507C-X2 runs on Solar Failsafe technology, harvesting ambient light to power the reticle when conditions allow, while a CR1632 battery provides backup illumination rated for 10,001 to 25,000 hours of use. Shake Awake technology powers the optic on with motion and puts it to sleep during inactivity, conserving battery life without sacrificing readiness. 12 brightness settings cover daylight and low-light operation.

A rugged hardcoat anodized aluminum housing keeps the optic lightweight at approximately 1.5 oz while standing up to recoil and rough handling. The 507C X2 uses the popular RMR footprint for broad pistol-slide compatibility with aftermarket mounting plates and cut slides.
