In 1960 a milestone in Colt history began with the introduction of the AR-15 semiautomatic rifle, followed by the M16 military full-automatic version. Involvement of the United States in Vietnam again put heavy demands on Colt to supply arms for the troops. In 1964, Coltís parent company reorganized under the name Colt Industries and the firearms subsidiary became Colt's Inc., Firearms Division.
