Holosun HE407K-GR-X2 Open Reflex Sight (6 MOA Green Dot)
The Holosun HE407K-GR-X2 is a compact, open-emitter pistol red dot built around a 6 MOA green dot reticle and a true 1x sight picture. It uses a side-loading CR1632 battery tray and provides manual brightness control with Lock Mode to prevent accidental setting changes.
Features include Shake Awake technology, parallax-free performance with unlimited eye relief, and a 7075-T6 aluminum housing finished in anodize. The HE407K-GR-X2 uses the Holosun K footprint for direct-mount compatibility on K-pattern optic cuts.
