Holosun HS407K X2 Open Reflex Sight (6 MOA Red Dot)
The Holosun HS407K X2 is an open reflex pistol sight built around a crisp 6 MOA dot and a compact footprint for subcompact slide applications. It features Lock Mode to prevent inadvertent setting changes, along with Shake Awake for motion-activated operation and last-setting recall.
A side-mounted tray battery compartment runs on a CR1632 battery and keeps the optic powered with up to 50,000 hours of runtime (setting 6). Brightness is adjustable through 12 settings (10 daylight, 2 night-vision compatible), with a parallax-free design and unlimited eye relief.
