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 Holosun K footprint direct-mount pattern. Manual brightness control with Lockout Mode and Shake Awake power management keep operation simple for subcompact/micro-compact slide setups.
A side-loading CR1632 battery tray allows battery changes without removing the optic, and the 7075-T6 aluminum housing is sealed to an IP67 rating.
