This is a very desirable rifle for the U.S. Military collector. These rifles were manufactured using original GI M1919 parts set that was assembled on to a new made NFA-legal semi-automatic sideplate/receiver. During the manufacturing process they were engineered or remanufactured to be able to fire in a semi-automatic mode only making them completely NFA/ATF compliant. The Model 1919 machine gun was developed and fielded shortly after WWI and was used extensively throughout WWII, Korea and even into Vietnam. They proved to be one of the most durable, reliable and effective machine guns and were heavily used by the U.S. Army and USMC. This model was made to duplicate the weight, feel, functioning and firing (in a semi-automatic mode) of the original 1919A6 guns. The side of the receiver is marked "U.S. GOVERNMENT/MODEL 1919 A4/A6 MACHINE GUN/CALIBER .30 SEMI AUTO/VERNONIA OR." over serial number, 000328. Includes four cloth ammunition belts.
