Description
Holosun HS507C-X2 Red Dot Sight swaps Holosun's usual reticle menu for the Primary Arms ACSS Vulcan: a red 10 MOA chevron with a 250 MOA outer circle you can switch off. The chevron tip is a far finer aiming point than a 10 MOA dot would be, while the big circle is what your eye finds first at speed. Solar Failsafe sits on top, backing the CR1632 with light.
How It Compares
The switchable Multi-Reticle version is the HS507C-X2 MRS, and the same ACSS reticle in green is the HE507C-X2 ACSS. If you are still narrowing the field, read our pistol red dot picks.
Ideal For
- RMR-cut slides on full-size and compact pistols
- Shooters who want a precise tip rather than a dot
- Range days followed by defensive carry
- Anyone moving up from a plain single dot

Help & guidance
Product FAQs
Why does the Holosun HS507C-X2 ACSS use a chevron instead of a dot?
The HS507C-X2 ACSS uses a 10 MOA chevron because you aim with its tip, so it does not cover the target the way a 10 MOA dot would. The chevron is still easy to see at speed while giving a far finer aiming point.
Can I switch the outer circle off on the HS507C-X2 ACSS?
Yes, the 250 MOA outer circle on the Holosun HS507C-X2 ACSS is deactivatable, leaving the chevron on its own. The big circle is what your eye finds first at speed, so many shooters keep it on for close work.
What does Solar Failsafe actually do on the HS507C-X2 ACSS?
Solar Failsafe on the Holosun HS507C-X2 ACSS uses a solar panel to supplement the side-loading CR1632 battery. Daylight backs up the battery, which is rated up to 20,000 hours in this sight.
Will the Holosun HS507C-X2 ACSS fit my pistol slide?
The HS507C-X2 ACSS uses the Trijicon RMR footprint, so it suits RMR-cut slides on full-size and compact pistols. Check your slide cut against the RMR pattern before ordering.
What battery does the Holosun HS507C-X2 ACSS take?
The HS507C-X2 ACSS takes a CR1632, loaded from the side of the housing. It is rated up to 20,000 hours and Solar Failsafe supplements it in daylight.
What reticle does the HS507C-X2 ACSS have?
The Holosun HS507C-X2 ACSS carries the Primary Arms ACSS Vulcan reticle, a red 10 MOA centre chevron with a 250 MOA outer circle that can be switched off. It replaces Holosun's usual reticle menu.
Does the HS507C-X2 ACSS have Shake Awake?
Yes, the Holosun HS507C-X2 ACSS features Shake Awake motion activation. It works alongside Solar Failsafe and the side-loading CR1632 battery.
What are the turret clicks worth on the HS507C-X2 ACSS?
Windage and elevation adjust in 1 MOA clicks on the Holosun HS507C-X2 ACSS. Total travel is plus or minus 50 MOA for both windage and elevation.
Is the Holosun HS507C-X2 ACSS magnified?
No, the HS507C-X2 ACSS is a 1x sight that is parallax-free with unlimited eye relief. The viewing window measures 0.63 x 0.91 in (16 x 23 mm).
How tough is the HS507C-X2 ACSS housing?
The Holosun HS507C-X2 ACSS uses a 7075-T6 aluminium housing rated IP67. The reticle is projected by a 650 nm red Super LED emitter.
What comes in the box with the HS507C-X2 ACSS?
The box holds the Holosun HS507C-X2 red dot sight with ACSS Vulcan reticle, mounting hardware and a fitting tool, plus a CR1632 battery.
How does the HS507C-X2 ACSS compare to the HS507C-X2 MRS and the HE507C-X2 ACSS?
The HS507C-X2 MRS is the switchable Multi-Reticle version of the same sight, and the HE507C-X2 ACSS is the same ACSS reticle in green. The HS507C-X2 ACSS itself is the red ACSS Vulcan option.
