$674.70
Available on back-order
The Holosun HE507K-GR X2 (sold here as the HS507K-GR X2) is a micro open reflex sight for subcompact pistols. Its green 540nm Super LED drives the Multi-Reticle System, letting you choose a 2 MOA dot, a 32 MOA circle or the circle-dot combination, and it runs up to 50,000 hours on setting 6 from a side-loading CR1632 battery. The X2 generation adds Lock Mode. Built on Holosun’s K footprint, it is a direct fit for the SIG P365X/XL and suits Australian shooters who want a green reticle on a slimline optics-ready pistol.
Is the HE507K-GR X2 solar powered?
No. Holosun lists solar power as not fitted on the 507K X2 series; the legacy ‘Solar/Battery’ wording is incorrect for this model.
Why is it called HE507K-GR rather than HS507K-GR?
Holosun uses the HE prefix for its green (and other elite) emitters and HS for red. HE507K-GR X2 is the official model code; some retailers list it as HS507K-GR X2.
Which pistols does it fit?
The K footprint is a direct fit for the SIG Sauer P365X/XL. Slides with a four-boss interface need an adapter plate, which is not included.
Optics are supplied by 3 Gun Tactical, Licensed Firearms Dealer 50001578, Tingalpa QLD, and can be shipped Australia-wide.
