Colt Automatic Rifle
Produced by Colt
The Colt Automatic Rifle or Colt Light Machine Gun is a 5.56 mm NATO, open-bolt, automatic squad automatic weapon developed by Colt Defense. It is based on the M16A2/A4, and has a distinctive squared-off handguard, vertical grip, carrying handle and integrated bipod. 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. The family name was derived from the original AR-15 by adding "Colt", resulting in the CAR-15, to stand for Colt Automatic Rifle, even though the "AR" in AR-15 stands for Armalite Rifle, the original manufacturer. The CAR-15 weapons system consisted of the AR-15 and five variations, including the Colt Machine Gun and CAR-15 Heavy Assault Rifle.
