The Colt AR-15 is a lightweight, magazine-fed, gas-operated semi-automatic rifle. It is a semi-automatic version of the M16 rifle sold for the civilian and law enforcement markets in the United States. Colt's Manufacturing Company currently owns the AR-15 trademark and is used exclusively for its line of semi-automatic AR-15 rifles.
A bullpup firearm is one whose action is located behind the trigger instead of in front of it. This creates a weapon that is lighter and more compact and maneuverable than conventional firearm designs with the same barrel length, maintaining the same muzzle velocity and effective range.
The M14 rifle, officially the United States Rifle, Caliber 7.62 mm, M14, is an American selective fire battle rifle that fires 7.62×51mm NATO ammunition. It became the standard-issue rifle for the U.S. military in 1959 replacing the M1 Garand rifle in the U.S. Army by 1958 and the U.S. Marine Corps by 1965 until being replaced by the M16 rifle beginning in 1968. The M14 was used by U.S. Army, Navy, and Marine Corps for basic and advanced individual training (AIT) from the mid-1960s to the early 1970s.

The ArmaLite AR-10 is a 7.62×51mm NATO battle rifle developed by Eugene Stoner in the late 1950s and manufactured by ArmaLite, then a division of the Fairchild Aircraft Corporation. When first introduced in 1956, the AR-10 used an innovative straight-line barrel/stock design with phenolic composite and forged alloy parts resulting in a small arm significantly easier to control in automatic fire and over 1 lb (0.45 kg) lighter than other infantry rifles of the day. Over its production life, the original AR-10 was built in relatively small numbers, with fewer than 10,000 rifles assembled. However, the ArmaLite AR-10 would become the progenitor for a wide range of firearms.
The ArmaLite AR-18 is a gas-operated assault rifle chambered for 5.56×45mm NATO ammunition. The AR-18 was designed at ArmaLite in California by Arthur Miller, Eugene Stoner, George Sullivan, and Charles Dorchester in 1963 as an alternative to the Colt AR-15 design, a variant of which had just been selected by the U.S. military as the M16. A semi-automatic version known as the AR-180 was later produced for the civilian market. While the AR-18 was never adopted as the standard service rifle of any nation, its production license was sold to companies in Japan and the United Kingdom, and it is said to have influenced many later weapons such as the British SA80, the Singaporean SAR-80 and SR-88, the American Adaptive Combat Rifle, the Belgian FN F2000, the Japanese Howa Type 89 and the German Heckler and Koch G36.
Eugene Morrison Stoner was an American firearms designer who is most associated with the development of the ArmaLite AR-15 rifle that was redesigned as a civilian sporting rifle, then modified by Colt's Patent Firearm Company for the US military as the M16 rifle.

It was an attempt to create an optimal Special Operations close-to-medium range carbine for Close Quarter Battle (CQB). A 12-inch barreled micro-carbine and 16-inch barreled carbine version were created. Barrett ceased manufacturing the rifle in 2010.
The .30 Remington AR cartridge was created in 2008 by Remington Arms to fill a perceived gap in performance on large game between the .223 Remington and larger cartridges such as the .308 Winchester. Design of the cartridge is considered a joint effort between companies under the "Freedom Group" name through a private equity firm and included such companies as Bushmaster, DPMS and Remington itself. It is a rebated rim cartridge designed to fit Remington's R-15 semiautomatic hunting rifle. It was designed to fit the dimensional constraints of the AR-15 magazine and is based on a modification of the .450 Bushmaster, which in turn was based on the .284 Winchester.
