Details

Description

Holosun's best-known pistol optic, the Holosun HS507C-X2 Red Dot Sight is the open reflex sight that put Multi-Reticle System red dots on the map. A button press moves between a precise 2 MOA red dot, a fast 32 MOA circle, or both together as a circle-dot, which is why one sight ends up covering carry, range days and club competition.

How It Compares

Only ever want the dot? The HS407C-X2 drops the reticle options. The green-emitter equivalent is the HE507C-X2, and there is an auto-ranging reticle in the ACSS Vulcan. Our pistol red dot picks set the family out.

Ideal For

  • Optics-ready pistols cut for the RMR footprint
  • One sight asked to cover carry, range and competition
  • Shooters who want reticle options rather than a fixed dot
  • Buyers who would rather have the well-proven choice

Key Features

  • Multi-Reticle System: 2 MOA red dot, 32 MOA circle, or circle-dot
  • 650 nm red Super LED emitter
  • Solar Failsafe — a solar panel backs up the battery
  • Shake Awake; side-loading CR1632; up to 50,000 hours
  • 7075-T6 aluminium, IP67; RMR footprint

Help & guidance

Product FAQs

Why is the Holosun HS507C-X2 so widely used?

The HS507C-X2 combines the Multi-Reticle System, Solar Failsafe and a tough build, which makes it a dependable all-rounder rather than a specialist. It is Holosun's best-known pistol optic and the open reflex sight that put Multi-Reticle System red dots on the map.

Should I get the HS407C-X2 or the HS507C-X2?

The HS407C-X2 gives you a single 2 MOA dot, while the HS507C-X2 adds the 32 MOA circle and the circle-dot on top. Choose the HS507C-X2 if you want reticle options rather than a fixed dot.

Is there a green version of the HS507C-X2?

Yes, the HE507C-X2 is the same sight with a green emitter. The HS507C-X2 itself uses a 650 nm red Super LED.

Which pistol slides take the Holosun HS507C-X2?

The HS507C-X2 fits slides cut for the Trijicon RMR footprint. It suits optics-ready pistols already machined for that pattern.

What reticles does the HS507C-X2 offer?

The Holosun HS507C-X2 Multi-Reticle System gives a 2 MOA red dot, a 32 MOA circle, or both together as a circle-dot. A button press moves between them.

What battery does the Holosun HS507C-X2 take?

The HS507C-X2 runs on a side-loading CR1632 battery, rated up to 50,000 hours. Solar Failsafe uses a solar panel to back the battery up.

Does the HS507C-X2 have Shake Awake?

Yes, the Holosun HS507C-X2 includes Shake Awake motion activation. It sits alongside Solar Failsafe and the side-loading CR1632 in the power system.

What is the click value on the HS507C-X2 turrets?

Windage and elevation move in 1 MOA clicks on the Holosun HS507C-X2. Total adjustment travel is plus or minus 50 MOA in both axes.

Is the Holosun HS507C-X2 magnified?

No, the HS507C-X2 is a 1x sight that is parallax-free with unlimited eye relief. Its viewing window measures 0.63 x 0.91 in (16 x 23 mm).

How rugged is the HS507C-X2 build?

The Holosun HS507C-X2 uses a 7075-T6 aluminium housing with an IP67 rating. That build is part of why it is trusted for carry, range days and club competition.

What is included with the Holosun HS507C-X2?

You get the Holosun HS507C-X2 red dot sight, mounting hardware and a tool, and a CR1632 battery. Nothing else is needed to fit it to an RMR-cut slide.

Is there a version of the 507C with an auto-ranging reticle?

Yes, the ACSS Vulcan version of the HS507C-X2 offers an auto-ranging reticle instead of the Multi-Reticle System. The standard HS507C-X2 reviewed here uses the switchable dot, circle and circle-dot.

How quickly will my Holosun HS507C-X2 arrive?

Estimated UK delivery is 10 business days. It ships as genuine UK stock, so there are no import fees to pay on arrival, and checkout is secured by Shopify.
