The Springfield M1903, formally the United States Rifle, Caliber .30, Model 1903, is an American magazine-fed, bolt-action rifle used primarily during the first half of the 20th century.
It was officially adopted as a service rifle on June 19th 1903, and was officially replaced as a service rifle by the faster-firing, semi-automatic M1 Garand, starting in 1936. The M1903 saw notable use in World War I and World War II, and some cases in Vietnam. It was also used as a sniper rifle in WWII, Korea and Vietnam. Furthermore, it remains in use as a civilian firearm and among some drill teams into the 21st century.
