Red dot sights with Shield RMSc footprint

The Shield RMSc footprint is a standardised pattern of screw holes and recoil bosses. Optics built to it include the Shield RMSc itself, the Holosun 407K/507K in adapter setups, JPoint MRD and Burris FastFire C — and any mount, plate or slide cut machined for the Shield RMSc pattern takes any of them, whatever the optic's brand.

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