February 18, 2025

Which red dots will you be able to mount on the ,mount with RMSc or Shield RMSc footprint? Will you be able to install Sig Sauer Romeo Zero on the same plate as Shield RMSc? We cover the full compatibility of Shield RMSc footprint in this article.

Footprint compatibility explained

What does a "footprint" mean? The term footprint refers to a sctructure of the sockets and screw holes on the base of the optic device.

And what does it mean if the footprints are compatible?

Each optic sight has some base for mounting. The base consists of pins on various positions and holes for screws used for fixation of the sight to the mounts. If any two sights use the same base for mounting, we call that that they share the same footprint.

In this article we show which red dot sights share the same footprint.

Shield RMSc footprint pattern

Shield RMSc footprint consists of four sockets in the corners of the sight and of two screw holes in the rear of the sight.

The front as well as the rear socketes are 17mm / 0.66 inches far from each other. From the rear sockets to the front sockets the distance is 32,8mm / 1.29 inches. Position of these four sockets corresponds to position of pins that are on a mounting surface of any mount for this standard.

The screw holes are positioned in the rear part of the optic device. These function for fixation of the sight to the mounts. These two screw holes are 14mm / 0.55 inches far from each other.

The screws that are to be used for these screw holes are always included in the package with the sight.

Compatible red dots

The RMSc footprint is shared by many other manufacturers on the market.

Or will you mount it on a pistol? And will the pistol be optics ready (with pistol slide cut for red dot). Then you need to look for red dot mount with Shield RMSc footprint.
Or will it be standard pistol without such cut? Then you need to look for optic plate with Shield RMSc footprint.

Efficacité

Bonjour, mon expérience chez Optics Spot est très satisfaisante, produit conforme et reçu en 72h, j'ai du renvoyer l article car non compatible avec ma hausse et y a eu une très bonne communication avec Paul.
Les tarifs sont correcte les FDP aussi. Je recommande cette compagnie.

Everything ok.

Lieferung schnell wie angekündigt. Lieferstatus wurde mitgeteilt. Das Produkt passt wie bestellt. Alles ok, gerne wieder.

EXCELLENT!!!! As the Terminator says; I'll be back!

I ordered adjustable sights for my CZ 75 Shadow, but accidentally ordered the wrong one (without the white dots). I sent a mail on a Sunday, and that was answered the same day, and the order was changed instantly. The right set arrived from the Czech Republic to The Netherlands on Tuesday morning.

Thanks for the Excellent service Paul.
