Description
The Holosun HE507COMP-GR is an open reflex pistol sight built for competition. Its 1.1 x 0.87 in window is the largest in Holosun’s 507 family, and the green 540nm Super LED drives the Competition Reticle System (CRS): a 2 MOA dot combined with a selectable 8, 20 or 32 MOA circle. It runs up to 50,000 hours on setting 6 from a side-loading CR1632 battery, includes Shake Awake and Lock Mode, and mounts on the RMR footprint. It is a strong fit for Australian IPSC Production Optics and Carry Optics competitors who want a big window and a bright green reticle.

FAQ
Is the HE507COMP-GR solar powered?
No. Holosun lists solar power as not fitted on the 507COMP; it runs on the CR1632 battery only.
What is the difference between HS507COMP and HE507COMP-GR?
Same housing, window and CRS reticle; the HS version is red (650nm) and the HE-GR version is green (540nm).
Does it include a mounting plate?
The sight uses the RMR footprint and mounts directly to RMR-cut slides or RMR-pattern plates. Holosun’s product page does not list an adapter plate in the box.
