The Holosun HS507C X2 Red Dot Sight (HS507C-X2) is a 1x open-reflex pistol red dot sight on the Trijicon RMR footprint, with Holosun's Multi-Reticle System — a 2 MOA red dot, a 32 MOA circle, or both together as a circle-dot — and Solar Failsafe supplemental power. UPC 810047071174.
The circle is the fast option at close range and the 2 MOA dot is the precise one, and the switch between them is a button press rather than a parts change. Shake Awake sleeps the reticle when the gun is still and wakes it on movement, Lock Mode stops the settings being altered by accident, and the side-loading CR1632 tray gives up to 50,000 hours of runtime without unmounting the optic.
How it compares
For a single uncluttered dot on the same footprint, the HS407C X2 red dot sight drops the circle. The HS507C X2 with the ACSS Vulcan reticle replaces the Multi-Reticle System with a fixed chevron and ring. In green, see the HE507C X2 green dot sight; for a narrower slide, the HS507K X2 red dot sight carries the same reticle on the RMSc footprint.

Ideal for
- Section 1 long-barrelled pistols and revolvers held on a UK firearm certificate
- Pistol-calibre carbines where the 32 MOA circle speeds up close-range transitions

What reticle options does the Holosun HS507C X2 have?
The Holosun HS507C X2 Red Dot Sight uses the Multi-Reticle System, which switches between a 2 MOA red dot on its own, a 32 MOA circle on its own, and both together as a circle-dot. The circle is the quicker reference at close range and the 2 MOA dot is the more precise one at distance.
Is the Holosun HS507C X2 an RMR or an RMSc footprint optic?
The Holosun HS507C X2 uses the Trijicon RMR footprint. It fits slides cut for an RMR and optics-ready pistols supplied with an RMR-pattern adapter plate. For the smaller RMSc footprint, the HS507K X2 carries the same Multi-Reticle System.
Will the Holosun HS507C X2 fit a Glock MOS?
Yes, using the RMR-pattern plate from the Glock MOS adapter set. Because the Holosun HS507C X2 has the Trijicon RMR footprint, any optics-ready pistol needs the RMR-pattern plate rather than the RMSc one.
What do Solar Failsafe and Shake Awake do on the HS507C X2?
Solar Failsafe takes supplemental power from ambient light and keeps the reticle lit if the CR1632 fails. Shake Awake switches the reticle off when the Holosun HS507C X2 has been still and restores it instantly on movement, which together support the 50,000-hour runtime rating.
What battery does the Holosun HS507C X2 use and how is it changed?
The Holosun HS507C X2 uses one CR1632 cell in a side-loading tray, so the battery can be replaced with the optic still mounted and zeroed rather than removing it and re-zeroing afterwards.
How is the standard HS507C X2 different from the ACSS Vulcan version?
The standard Holosun HS507C X2 uses the switchable Multi-Reticle System. The HS507C X2 ACSS Vulcan version instead uses a fixed 10 MOA chevron inside a large guidance circle, which cannot be switched to a plain dot.
