"As the U.S Army ramped up its small-arms complement for World War I, it sought submissions for a machine gun. A May 1917 test at Springfield Armory arranged by John Browning saw an example of his M1917 design fire 39,500 rounds before experiencing any parts breakage. A later production model underwent another rigorous test, firing more than 21,000 rounds in a continuous burst that lasted 48 minutes and 12 seconds."
For those who dont know, the M1919 is the air-cooled version of the water-cooled M1917. Same action, just different barrel setups.
