Who invented the first machine gun?
Machine gun
Many heavy machine guns, such as the Browning M2 .50 caliber machine gun, are accurate enough to engage targets at great distances. During the Vietnam War, Carlos Hathcock set the record for a long-distance shot at 7,382ft (2,250m) with a .50 caliber heavy machine gun he had equipped with a telescopic sight.[3] This led to the introduction of .50 caliber anti-materiel sniper rifles, such as the Barrett M82.
