History and Evolution
The AR-15 rifle has a rich history that dates back to the late 1950s. It was designed by Eugene Stoner, an American firearms designer, while working for Armalite. The “AR” in AR-15 stands for Armalite Rifle, not Assault Rifle. This innovative firearm was created with the vision of producing a lightweight, modular, and easy-to-maintain rifle for both military and civilian use.
After Armalite, the production rights of the AR-15 were sold to Colt Manufacturing Company. Colt then sold the rifle to various military organizations, including the United States military. The rifle was adopted by the U.S. military as the M16 rifle. However, Colt continued to sell the semi-automatic version of the rifle to civilians and law enforcement agencies under the AR-15 name.
