In 1974, Springfield Armory of Geneseo, Illinois began offering a civilian-legal semi-automatic rifle based on the M14, which it christened the M1A. Since then, Springfield Armory has offered several versions of the rifle, including a number of carbines utilizing a 16.25-inch-long barrel. 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. This was a simplification of the Socom II we covered in 2012 that featured a multi-rail forend made by Vltor Weapons Systems. The subject of this evaluation is the newest carbine, the $2442 Socom 16 CQB. The CQB uses the same barreled action as previous carbines but sheds the traditional stock in favor of a carbon-fiber-reinforced polymer stock by Archangel featuring a 5-position adjustable-length buttstock.
