Two criticisms....By the way, AR stands for ArmaLite Rifle, which is manufactured by Colt Manufacturing Co.
AR stands for ArmaLite, period. While it is true that they mostly built rifles, ArmaLite has also designed and built pistols and shotguns, the model numbers of which also begin with"AR". The number following the "AR" designation is merely the firearm's design number.
Furthermore, this article is dated a full month after Colt's announced that it was stopping manufacture of AR15s for the civilian market.
Other than that, the article is pretty much correct.
