Romeo Zero / Pic. rail mount

[softcock]

Hey .. info needed. from someone who has mounted several different micro red dots .
Is the little Sig.Romeo Zero a proprietary footprint ?
Just picked one up and I have an RMR mount Pic.rail attachment sitting here, I don't even have to take the Romeo zero out of the package to see, it looks to wide on the 2 little insert knobs and incorrect spacing for the 2-screws .

Is there any mount options on for fitting the Sig.Romeo zero's ? , Does the Romeo Zero even have same footprint as the similar Romeo 1 micro ?

.....thanks
