FAQ
Is HS507C-GR X2 the same as HE507C-GR X2? Yes. Holosun uses the HE prefix for its green (and gold) reticle models and HS for red; the green 507C X2 is catalogued by Holosun as HE507C-X2-GR.
Why choose a green reticle? Holosun’s 540nm green LED sits near the peak sensitivity of the human eye, which many shooters find easier to pick up against mixed backgrounds than red.
What footprint does it use? The RMR footprint, so it fits RMR-cut slides directly and MOS or other optic-ready pistols with the correct adapter plate.
