The subject of this evaluation is the newest carbine, the $2442 Socom 16 CQB. This was a simplification of the Socom II we covered in 2012that featured a multi-rail forend made by Vltor Weapons Systems. In the September 2014 issue of Gun Tests, we evaluated the Springfield Armory Socom 16, which added a scout-style scope mount positioned forward of the ejection port.
