Holosun HE507K-GR X2 Green Multi-Reticle Open Reflex Sight
The Holosun HE507K-GR X2 is an open reflex pistol sight built around the Holosun K footprint for micro-compact/subcompact slide cuts. It uses Holosun’s green Multi-Reticle System with selectable 2 MOA dot, 32 MOA circle, or circle-dot reticle options, backed by 12 brightness settings including 2 night-vision compatible levels.
Key features include Shake Awake and Lock Mode to prevent inadvertent setting changes. Power comes from a CR1632 battery housed in a convenient side-mounted tray. The optic is built from 7075-T6 aluminum with an anodized finish and carries an IP67 submersion rating.
