The Holosun HE509T X2 Gold Dot Sight (HE509T-X2-GD) is a 1x fully enclosed pistol gold dot sight in a nitrogen-purged Grade 5 titanium housing on the 509T footprint, with the Multi-Reticle System — a 2 MOA gold dot, a 32 MOA circle, or both together as a circle-dot. An RMR-to-509T adapter plate is included.
The gold emitter is the reason to choose this variant: it shows as a warm amber reticle that separates from red-painted steel, orange targets and autumn woodland where a red dot can wash out. Everything else is the toughest specification Holosun builds — a sealed, nitrogen-purged emitter inside a Grade 5 titanium housing, with Solar Failsafe, Shake Awake and Lock Mode, and a CR1632 rated at up to 50,000 hours.
How it compares
The same optic is available in HE509T X2 red and HE509T X2 green. For an open-emitter titanium optic on the RMR footprint, see the HE508T X2 red dot sight. For a gold reticle in an aluminium open-emitter housing, the HS507C X3 gold dot sight is the standard option. Browse every gold dot sight and enclosed red dot sight we stock.
Ideal for
- Section 1 long-barrelled pistols and revolvers held on a UK firearm certificate
- Shooters who lose a red reticle against red-painted steel or autumn backgrounds
- All-weather outdoor use, where a sealed emitter keeps the reticle clear
- Practical shotgun and pistol-calibre carbine builds using a 509T Picatinny mount

What is a gold dot and why choose one?
The Holosun HE509T X2 Gold Dot Sight uses a gold emitter rather than red or green, giving a warm amber reticle. It separates more clearly than red from red-painted steel, orange targets and autumn woodland, and is otherwise the same optic as the red and green versions.
What footprint does the Holosun HE509T X2 Gold use?
It uses the native 509T footprint rather than RMR or RMSc. An RMR-to-509T adapter plate is supplied in the box, so it can also be mounted to RMR-cut slides and RMR-pattern mounts.
Is the Holosun HE509T X2 Gold fully sealed?
Yes. The Holosun HE509T X2 Gold has a fully enclosed emitter in a nitrogen-purged Grade 5 titanium housing, so rain, mud and dust cannot reach the LED and the glass will not fog internally.
What reticle options does the Holosun HE509T X2 Gold have?
It uses the Multi-Reticle System, which switches between a 2 MOA gold dot on its own, a 32 MOA circle on its own, and both together as a circle-dot.
What battery does the Holosun HE509T X2 Gold use?
It runs on a CR1632 cell, with Solar Failsafe supplementing it from ambient light and Shake Awake sleeping the reticle when idle, for a rated runtime of up to 50,000 hours.
What is Lock Mode on the Holosun HE509T X2 Gold?
Lock Mode disables the buttons once brightness and reticle are set on the Holosun HE509T X2 Gold, so the settings cannot be changed by accident in a holster, a case or a range bag.
