The Holosun HE507C X2, part HE507C-GR X2, is a 1x open-reflex pistol sight on the Trijicon RMR footprint with a green Multi-Reticle System and Solar Failsafe power.
One button changes the sight from a 2 MOA dot to a 32 MOA circle to both at once, which is the difference between a precision optic and a speed optic without buying two.
The aluminium housing is 7075-T6, rated IP67 and tested to 5000G, weighing 1.5 oz over a 0.91 x 0.63 in window. A CR1632 cell drops into a tray in the side of the body, so it can be replaced with the sight still bolted down and zeroed, and Holosun rate it at up to 50,000 hours. The solar panel on top supplements the cell and keeps the reticle lit in daylight even if the battery has died, while Shake Awake sleeps the sight when it is idle and X2 Lock Mode disables the buttons once the settings are where you want them.
Green sits near the peak of human daylight sensitivity, which is why many shooters find the reticle easier to pick up than red against foliage or dark targets. Adjustment is 1 MOA per click with 50 MOA of travel either way, and twelve brightness levels run ten daylight and two night-vision compatible. The emitter is open rather than sealed, which keeps the sight compact but means the LED window wants an occasional wipe in wet weather.
It bolts to any RMR-cut slide or to a mount and plate on the RMR pattern. If you want the same reticle set on a narrower slide, the HE507K X2 is the smaller version, the ACSS Vulcan version swaps the Multi-Reticle System for a chevron and ring, and the HE507C X3 is the later generation.
