Frequently Asked Questions

Why choose a green dot over Holosun’s standard red dot version?
Some shooters find a green reticle easier to pick up quickly in bright daylight; this HE507C-GR-X2 shares the same ACSS Vulcan pattern and electronics as the red-dot HS507C-X2, just with a green emitter.

How is the battery replaced on this sight?
The CR1632 battery sits in a side-loading tray that slides out, so you can replace it without removing the optic from your pistol.
