Details
Description
Holosun's X3 generation reworked the glass without changing the idea, and the Holosun HE407C-X3 Green Dot Sight is the plain-dot member of it: a single 2 MOA green dot, refined optics for a cleaner picture than the X2 generation, and no reticle menu to step through. The window runs 0.91 × 0.67 in, so there is a good amount of glass around that dot.
How It Compares
If you would rather have a switchable circle-dot in the same X3 body, that is the HE507C-X3. The identical sight in other emitter colours: HS407C-X3 Red or Gold. Browse the rest of our green optics and the wider Holosun range.
Ideal For
- Optics-ready pistols and rifles cut for the RMR footprint

Product FAQs
Should I get the HE407C in X2 or X3?
The X3 is the newer generation, with refined optics for a cleaner view, and the core feature set is shared between them. The HE407C-X3-GR is the plain-dot member of the X3 generation.
What will the Holosun HE407C-X3 mount to?
It uses the Trijicon RMR footprint. Our footprints guide explains how to check your slide against that pattern.
Why choose green over red on the HE407C-X3?
Plenty of shooters simply pick a green dot up faster, and beyond the emitter this is the same sight as the red version. The HE407C-X3-GR uses a Green Super LED of the X3 generation.
Can I change the battery on the HE407C-X3 in place?
Yes, the CR1632 loads from the side, so the sight does not come off the gun. Battery life is rated up to 50,000 hours.
What reticle does the Holosun HE407C-X3 have?
It has a single 2 MOA green dot with no reticle menu to step through. If you want a switchable circle-dot in the same X3 body, the HE507C-X3 is the alternative.
How big is the window on the HE407C-X3-GR?
The viewing window is 0.91 by 0.67 in, which is 23 by 17 mm. That gives a good amount of glass around the dot.
What are the adjustment clicks on the HE407C-X3?
Windage and elevation adjust in 1 MOA clicks. Total travel is plus or minus 50 MOA in both windage and elevation.
Does the Holosun HE407C-X3 have Solar Failsafe?
Yes, a solar panel backs up the battery on the HE407C-X3-GR. Shake Awake is also included alongside the side-loading CR1632.
How tough is the HE407C-X3-GR?
The housing is 7075-T6 aluminium and rated IP67. That suits it to everyday carry and range use.
Does the HE407C-X3 come in other colours?
Yes, the identical sight is offered as the HS407C-X3 Red and the HS407C-X3 Gold. Only the emitter colour differs.
What is included with the Holosun HE407C-X3?
The box contains the Holosun HE407C-X3 green dot sight, mounting hardware and a tool, and a CR1632 battery.
How long does UK delivery take for the HE407C-X3-GR?
Estimated UK delivery is 10 business days. It ships as genuine UK stock, so there are no import fees to pay on arrival. Checkout is secured by Shopify.
