Just got two Sig Romeo 4S for two or my AR pistols; needless to say, I am impressed with the quality, fit, battery life, being able to change reticle to one similar to my Eotech’s, and that they are made in U.S. The Mount is a QD Mount,  easy to take off and install, but I would like to change it out to a Geissele Super Precision DDC Mount DDC. I have heard the Sig Romeo 4S mounts are similar to the Aimpoint T-1/H-1’s, but nothing sure. Can someone confirm this? Thanks

I've got a Romeo 4S mounted on a Geissele Super L1/3 T1 mount, no problem.

I have a 4h and a 4DR mounted on aimpoint mounts.

One on a ADM and one on a Super G
