I recently purchased a Sig Romeo 4S for my SBR. It came with two mounts, a low and full co-witness mount. The full is still a little too short causing me to turtle neck on the stock to see through the center of the optic. I was searching around for risers, but the risers I found would obstruct my back up sights and not allow me to use a magnifier.
American Defense makes an EoTech riser that would be long enough to use a magnifier on the riser and probably the rear back up as well, but my front sight would still be too low.
Knights Armament makes an NVG mount that will allow you to raise the optic to 2.33", keep back ups at receiver height and allow the use of a magnifier. The mount is designed for Aimpoint micro mounts, but I can't find any solid info if Sig uses Aimpoint bolt patterns. I have only found one source that says it does, but I would like to have a little more confirmation before dropping $230 on a KAC mount.
