223 Ammo History and Specs

223 ammo is virtually identical in external dimensions to the 5.56x45mm NATO rifle cartridge. 223 ammo, however, is both lighter and shorter than the 5.56x45mm. Compatible with the AR-15, 223 ammo is one of the most popular types of rifle cartridge in the U.S.

Born of a combination of the 222 Remington and 222 Remington Magnum models, 223 ammo was created in 1964. This new design was undertaken to provide a high performance round that fit the action length of a certain weapon known as the M16 rifle, that was about to step into the American military spotlight at the dawn of the war in Vietnam. The 223 ammo for sale here at GunBroker.com uses the same design as when it was introduced and before becoming one of the most widely known cartridges around. The ammo type's popularity was driven up even more when the AR-15—the semi-automatic version of the military's M16--became available for use by the civilian population.
