The SIG 556 SBR Details will be posted soon. The Photos is this ad are NOT the SIG 556 SBR as described to me by SIG. The SIG556 SBR will have the Swiss Side Folder as seen on the Classic Series, it will not have a Red Dot but will have a rear Diopter Sight. The hand guards will be the SWAT Style Quad Rail and not the blocky plastic version.
