Holosun HS507COMP Open Reflex Red Dot (Large Window, PRS Reticle, RMR Footprint)
The Holosun HS507COMP is an open-emitter pistol red dot built around a large 1.1" x 0.87" viewing window and Holosun’s Performance Reticle System (PRS) for fast reticle acquisition and tracking.
This optic uses a 650nm LED with selectable reticle options (2 MOA dot with 8/20/32 MOA circle choices), features Shake Awake and lockout mode, and runs on a side-loading CR1632 battery tray to allow battery changes without removing the optic.
