![]() ġ973 Colt AR-15 SP1 rifle with 'slab side' lower receiver (lacking raised boss around magazine release button) and original Colt 20-round box magazine The "AR" in AR-15 actually stands for "ArmaLite Rifle", and "AR-15" is most-commonly used to refer only to the civilian semi-automatic variants of the rifle which lack the fully automatic function. Terminology Ī common misconception is that "AR" is an abbreviation for " assault rifle" or " automatic rifle", perhaps because of the weapon's inclusion in the Federal Assault Weapons Ban in 1994, or because the ArmaLite AR-15 was originally designed to replace the M14 rifle in the Vietnam War. Promoted as "America's rifle" by the National Rifle Association, their popularity is partially attributable to active restrictions, or proposals to ban or restrict them. In the 2010s, AR-15-style rifles became one of the "most beloved and most vilified rifles" in the United States, according to The New York Times the rifles have gained infamy due in part to their use in high-profile mass shootings. After the term modern sporting rifles was coined in 2009 by the US National Shooting Sports Foundation, a firearms trade association, it was quickly adopted by much of the industry. The Federal Assault Weapons Ban restricted the sale of the Colt AR-15 and some derivatives in the United States from 1994 to 2004, although it did not affect rifles with fewer listed features. While the patents are expired, Colt retained the trademark of the AR-15 name and is the sole manufacturer able to label their firearms as AR-15. After most of the patents for the Colt AR-15 expired in 1977, many firearm manufacturers began to produce copies of the Colt AR-15 under various names. ![]() ArmaLite sold the patent and trademarks to Colt's Manufacturing Company in 1959, resulting in the Colt AR-15, which removed the selective fire feature. The original ArmaLite AR-15, its predecessor, was a scaled-down derivative of Eugene Stoner's ArmaLite AR-10 design and featured selective fire.
