The Holosun HE507C X2 is the green-emitter version of the world's most popular pistol red dot platform — an open-reflex optic with a big, clear window and Holosun's full feature set. The green reticle is often easier to pick up in bright daylight than red.
Its Multi-Reticle System switches between a 2 MOA dot, a 32 MOA circle, or the circle-dot combined. Solar Failsafe powers the dot from light and keeps it lit if the battery dies, Shake Awake sleeps it when idle, and X2 Lock Mode prevents accidental setting changes. It uses the RMR footprint.

Frequently Asked Questions
Will it fit my pistol?
It uses the RMR footprint — it fits RMR-cut slides and optics-ready pistols with an RMR plate. Confirm your slide cut first.
Green or red?
Many shooters find green easier to pick up in daylight; a red version (HS507C X2) is also available.
What does Solar Failsafe do?
It powers the dot from available light and keeps it lit even if the battery fails.
What is Lock Mode?
The X2 control system lets you lock the buttons so settings can't change accidentally.
