Holosun HS507K-X2 | 2 MOA & 32 MOA | Black

The Holosun HS507K-X2 is an open-reflex optical sight engineered for subcompact pistol applications. It uses Holosun’s Multi-Reticle System to offer a 2 MOA dot and a 32 MOA circle from the same LED source, and adds Lock Mode to prevent inadvertent button changes. The optic includes Shake Awake power management and a side-mounted battery tray for convenient replacement.

Its small footprint and features make the HS507K-X2 well suited to concealed-carry pistols and for target/trigger-discipline training at the range. The sight provides a parallax-free aiming point with unlimited eye relief for intuitive sighting.
