The AR-15 is the civilian version of the M-16 military rifle. The rifle was developed in the 1950s by the ArmaLight company. The new space age looking, light weight rifle was originally rejected by the Army but after finally being accepted it was designated the M-16. The rifle was sold in a civilian version, and was called the AR-15 which stood for ArmaLight rifle 15. The only difference between the original AR-15 and the M-16 was that the M-16 could fire full auto. It is illegal for the general public to own full auto weapons without a federal license. Today, versions of the AR-15 are produced and sold by many different gun makers. The AR-15 is as controversial as it is popular.
