Wow! Someone finally mentioned Arma Lite Rifle. Its been around since the 60s. Eugene Stoner, Colt... and all that history has been ignored for 60 years.
And that history is still being ignored, by a lot of people, including the current owners of the company:
ArmaLite AR-9 = shotgun
ArmaLite AR-17 = shotgun
ArmaLite AR-24 = handgun
As Mark Westrom, the previous owner of ArmaLite (and a retired U.S. Army ordnance officer) noted repeatedly:
AR stands for ArmaLite.
