Red dot sights with Holosun 509T footprint

The Holosun 509T footprint is a standardised pattern of screw holes and recoil bosses. Optics built to it include the Holosun 509T and SCRS series — and any mount, plate or slide cut machined for the Holosun 509T pattern takes any of them, whatever the optic's brand.

Before ordering, confirm your mount, plate or slide cut is machined for the Holosun 509T pattern — the pattern decides the fit. Reticle, window size and dimensions for each sight are under Key specifications on the product page.
