FAL

The Fusil Automatique Leger, or Light Automatic Rifle (LAR), also known as the "right arm of the free world," the FAL rifle was the NATO equivalent to the AK-47, in terms of the sheer number of countries that adopted it. Unlike the AK-47, it utilized a full-power rifle cartridge (the 7.62x51mm NATO standard round). The FAL was made by Fabrique Nationale de Herstal.
