The Holosun HE509T X2 in green is a 1x fully enclosed pistol sight built on the native 509T footprint, in a nitrogen-purged titanium housing.
Titanium and a sealed emitter make this the toughest of Holosun's mini reflex sights, and green is the colour the human eye reads brightest for a given amount of power.
The Multi-Reticle System switches between a 2 MOA dot, a 32 MOA circle and the two together, in green at 540nm behind a 0.66 x 0.9 in window. The housing measures 1.6 x 1.16 x 1.13 in at 1.27 oz, is rated IP67 and tested to 5000G, and being nitrogen-purged it will not fog from the inside. Eye relief is unlimited and the sight is parallax-free.
A CR1632 gives up to 50,000 hours at setting 6, backed by Solar Failsafe drawing on ambient light and Shake Awake sleeping the reticle when the pistol is still, with a lock mode to stop settings being knocked in a holster. Illumination runs to eight daylight settings and four night-vision levels, and the turrets move 1 MOA per click with 30 MOA either side of centre. The footprint is worth checking first: it is the 509T pattern, with an RMR-to-509T plate included for RMR-cut slides, and it will not sit on an RMSc slimline cut.

What the HE509T X2 Green fits
Slides cut for the 509T take it directly, and the supplied plate carries it onto RMR-cut slides and RMR-pattern mounts, including rifle and shotgun mounts on that pattern. The same optic comes in red and gold; for an open-emitter titanium sight in green on the RMR footprint, see the HE508T X2 green.
