By January 15, 1919, the rate of producing machine guns had been cut in two. By June 28, all production of machine guns had stopped. The Springfield and Rock Island arsenals, always the Army’s development and manufacturing centers for small arms, were selected to receive the reserve manufacturing equipment acquired by the Ordnance Department in the prosecution of the machine-gun project. One unit of machinery sufficient for the daily manufacture of 100 Browning heavy machine guns, and another unit for the daily manufacture of 200 Browning automatic rifles were stored at Rock Island Arsenal. This reserve machinery was worth about $4,275,000. Similar measures were taken in the demobilization of the war rifle industry. Production was curtailed gradually, ceasing entirely in March, 1919. Three great private plants and two government factories (Springfield Armory and Rock Island Arsenal) built our war rifles. The War Department invested over $22,000,000 in machinery. With this machinery the rifle-making departments of the Springfield Armory and the Rock Island Arsenal were practically reëquipped to produce the Model of 1903 (Springfield) rifle. The Springfield Armory (the chief future manufacturing center for this arm) was equipped to make 1,000 of these rifles in an 8-hour day, and Rock Island, 600. Working at full speed, both centers can produce 3,500 Springfield rifles every twenty-four hours. In addition special small tools, jigs, and fixtures sufficient for the production of 1,000 Model of 1917 (Enfield) rifles daily were stored at the Springfield Armory, and a unit of manufacturing equipment for producing 500 automatic pistols daily was also stored at Springfield.
