The Barrett M82, standardized by the U.S. military as the M107, is a recoil-operated, semi-automatic anti-materiel rifle developed by the American Barrett Firearms Manufacturing company. Despite its designation as an anti-materiel rifle, it is used by some armed forces as an anti-personnel rifle. It is also called the Light Fifty for its .50 BMG (12.7x99mm NATO) chambering and significantly lighter weight compared to previous applications.
