Point of fact: AR-15 is actually a trademark owned by Colt. That’s why there’s the Ruger AR-556, and the S&W M&P 15 Sport II, which are marketed as AR-15 style rifles. Kinda like Styrofoam; people misuse the trademark (esp. styrofoam cups; such a thing has never existed) regularly, but it’s still owned by the Dow Chemical Corp. (Or was; I think they sold that division off to E.I. DuPont de Nemours & Co.)
