The Armalite AR-18 rifle was designed in the 1960s by American engineer Arthur Miller and was intended as a more affordable and simpler alternative to the AR-15/M16. Chambered in 5.56x45mm NATO, the AR-18 featured a gas-operated, short-stroke piston system, which was designed for reliability in adverse conditions. Its stamped steel construction made it easier to manufacture, especially for countries with less advanced industrial capabilities, positioning the AR-18 as a cost-effective option for military forces worldwide.

Although the AR-18 saw limited direct adoption by major militaries, with production figures estimated around 20,000 units, it was produced under license by companies such as Howa in Japan and Sterling Armaments in the United Kingdom. While it did not achieve widespread service, the AR-18 was notably used by the Irish Republican Army (IRA) during the Troubles in Northern Ireland, where it gained notoriety as the "Armalite" in the context of armed resistance. Its compact and modular design also made it adaptable for special forces and irregular warfare.

Despite its limited adoption, the AR-18 is highly regarded for its innovative design, and its influence can be seen in later firearms, including the British SA80 and the German G36. Known for its reliability, ease of maintenance, and adaptability, the AR-18 remains an iconic weapon in modern firearms history. Today, it is appreciated by collectors and firearms enthusiasts, and its impact on later military rifle designs solidifies its reputation as an influential firearm that introduced several key advancements.
