Normally I am the first to mock journalists that do not understand gun terminology, but normally it is them calling an AR a machine gun... Many of the the things there look like they could be full auto or select fire and the article seems to have properly used the term "short barreled rifle." They seem to actually have a basic understanding of the NFA... I think I will give them a pass on not knowing the difference between a FA/SF rifle and a proper light machine gun.
