These weapons were all designed to fill the role of the earlier Browning Automatic Rifle. The Colt/Diemaco weapon traces its lineage to a number of weapons developed both at Colt and by the U.S. In 2005, Diemaco was acquired by Colt's Manufacturing LLC and renamed Colt Canada. Originally known as the Colt M16 LMG or simply as the Colt LMG ( Light Machine Gun), this weapon was developed as a joint venture by Colt and Diemaco, a Canadian firm licensed by Colt in 1982 to produce variants of the M16 family for the Canadian Armed Forces. The Colt Automatic Rifle is the name of a current product, but Colt has developed a number of similar weapons since the company obtained the rights to produce the Armalite AR-15 family at the end of the 1950s.
It is one of many squad automatic weapon-type firearms that have been developed from the Armalite AR-15 that use the Stoner bolt and carrier piston system. It is based on the M16A2/A4, and has a distinctive squared-off handguard, vertical grip, carrying handle and integrated bipod. The Colt Automatic Rifle or Colt Light Machine Gun is a 5.56 mm NATO, open-bolt, full-automatic-only firearm developed by Colt Defense.
