The Holosun HE507C X3 Green Dot Sight (HE507C-X3-GR) is a 1x open-emitter pistol green dot sight on the Holosun 507C / Trijicon RMR footprint, with the Multi-Reticle System — a 2 MOA green dot, a 32 MOA circle, or both together as a circle-dot — in a 7075-T6 aluminium housing weighing 1.5 oz (43 g).
It is the green-emitter version of Holosun's third-generation full-size pistol optic. Green reads brighter to the human eye than red at the same output, the 32 MOA circle is the fast reference at close range and the 2 MOA dot is the precise one, and the X3 housing adds a forward-facing light sensor so automatic brightness follows the light on the target. Solar Failsafe backs up the side-loading CR1632, with Shake Awake and Lock Mode.
How it compares
For a single green aiming point with no circle, the HE407C X3 green dot sight is the simpler option. The same Multi-Reticle System is available in HS507C X3 red and HS507C X3 gold. The previous generation, the HE507C X2 green dot sight, shares the footprint and battery, and the HE507 ProMax green dot sight is the larger-window competition option. Browse the full Holosun green dot sight range and all RMR footprint red dot sights.
Ideal for
- Section 1 long-barrelled pistols and revolvers held on a UK firearm certificate
- Shooters who pick up a green reticle faster than red in woodland and low light
- Pistol-calibre carbines where the 32 MOA circle speeds up close transitions
- Airsoft GBB pistol builds and range training guns

What reticle options does the Holosun HE507C X3 have?
The Holosun HE507C X3 Green Dot Sight uses the Multi-Reticle System, which switches between a 2 MOA green dot on its own, a 32 MOA circle on its own, and both together as a circle-dot.
What footprint does the Holosun HE507C X3 use?
The Holosun HE507C X3 uses the Holosun 507C footprint, which is the Trijicon RMR pattern, so it fits RMR-cut slides and optics-ready pistols supplied with an RMR-pattern adapter plate.
Why choose a green reticle over red on the HE507C X3?
The human eye is more sensitive to green than to red at the same output, so the reticle on the Holosun HE507C X3 usually appears brighter and better defined for the same power draw, and it is easier to see for shooters with a mild red-green colour deficiency.
What is new on the X3 compared with the X2?
The Holosun HE507C X3 has a revised housing with improved ergonomics and a forward-facing light sensor, so automatic brightness responds to the light on the target rather than the light behind the shooter. The Multi-Reticle System, RMR footprint, CR1632 battery and Solar Failsafe carry over from the X2.
What battery does the Holosun HE507C X3 use and how is it changed?
The Holosun HE507C X3 uses one CR1632 cell in a side-loading tray, so the cell can be replaced with the optic still mounted and zeroed. Holosun rates the runtime at up to 50,000 hours.
Is the Holosun HE507C X3 waterproof?
The Holosun HE507C X3 is rated IP67, which covers full dust protection and immersion in water, in a 7075-T6 aluminium housing weighing 1.5 oz (43 g).
