The Holosun HS407C X2 is a 1x open reflex pistol red dot sight carrying a single 2 MOA red dot on the Trijicon RMR footprint.
One dot and nothing around it — no circle, no chevron, nothing else in the window to look past when the only thing you need is an aiming point.
The housing is 7075-T6 aluminium rated IP67, weighing about 1.5 oz behind a 0.91 × 0.63 in window, with a side-loading CR1632 tray so the cell changes without pulling the sight off the slide.
X2 is the generation that added Lock Mode, which stops the buttons changing anything by accident once you have set the brightness, and Shake Awake, which sleeps the dot when the gun is still and lights it the moment it moves. Twelve settings run from an indoor gallery to full summer glare, two of them night-vision compatible. Adjustment is 1 MOA per click across ±50 MOA, and Solar Failsafe draws on ambient light to keep the dot lit if the cell gives up. The emitter is open, so it can be blanked by heavy rain or mud in a way an enclosed sight cannot.

What the HS407C X2 fits
It mounts to any slide cut for an RMR, and to an optics-ready pistol through the RMR-pattern plate from its adapter set. A narrower slide cut for RMSc takes a K-series sight such as the HS407K X2 instead. For a ranging reticle rather than a plain dot, see the HS507K X2 ACSS Vulcan. More sit in RMR footprint red dot sights.
