I really want more clarification on the first paragraph. From the author's awkward lingo ("safety key") I get the impression that they do not grasp the technical or legal differences between a semi-automatic AR-15 clone and a fully-automatic M-16. I have a hard time believing that Wilson manufactured a functional M-16 lower, assembled it with a full-auto bolt carrier and had a journalist fire it. That is an unequivocal violation of federal law (since no new machine guns have been allowed for Form 1 manufacture since May of 1986) as opposed to constructing a semi-automatic firearm for personal use. Such confusion in the opening paragraph makes me heavily discount the rest of the article.
