The Holosun HS507C X2 with the ACSS Vulcan reticle takes the world's most popular pistol red dot and swaps its multi-reticle system for Primary Arms' acclaimed ranging reticle — a precise chevron tip inside a large outer ring that funnels your eye back onto target fast and gives a finer aiming point than a round dot.
Everything else is classic 507C X2: an open-emitter, RMR-footprint optic in a tough 7075-T6 housing with Solar Failsafe backup power and Shake Awake for up to 50,000 hours of runtime, all on a side-loading CR1632. In stock for fast UK dispatch.

Frequently Asked Questions
What is the ACSS Vulcan reticle?
A Primary Arms reticle that pairs a precise chevron aiming point with a large outer ring. The ring catches your eye for fast reacquisition, while the chevron tip gives a finer hold than a round dot.
What pistols does it fit?
It uses the Trijicon RMR footprint, so it mounts to any slide cut or adapter plate machined for an RMR.
How do I change the battery?
Via a side-loading CR1632 tray — no need to remove the optic or lose your zero.
What do Solar Failsafe and Shake Awake do?
Solar Failsafe keeps the reticle lit using light as backup power; Shake Awake sleeps the optic when idle and wakes it on movement — together giving up to 50,000 hours of runtime.
How is this different from the standard HS507C X2?
This model uses the fixed ACSS Vulcan chevron reticle; the standard 507C X2 uses Holosun's switchable Multi-Reticle System (2 MOA dot / 32 MOA circle / circle-dot).
