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,[1][2][3] the Singaporean SAR-80 and SR-88,[3] the Belgian FN F2000,[4] the Japanese Howa Type 89[5] and the German Heckler and Koch G36.[6][7][8]

If you ever take an SA80 apart, or see a picture of one fully disassembled, then look very closely at the bolt and gas system, as it's almost a direct copy of the old AR-18 system.

When the ArmaLite Model 18 was in its last days of production, weapons engineers at Enfield borrowed heavily from its design for 'inspiration' on their new 5.56mm rifle. Known then as the Enfield Weapons System and now as the L85, the bullpup rifle of the British military is at its heart a modified AR18 thrown into a radically different stock.

But the true legacy of the AR-18 is all the 'modern' firearms that have adopted the bolt carrier group and operating system such as the H&K XM8 & G36, Bushmaster/Remington ACR, FN SCAR 16/17, South Korea Daewoo K1/k2, British L85A1/SA80 as well as the Singaporean SAR-80/SAR-88.
