The M1903 or 1903A3 Springfield, formally the United States Rifle, Caliber .30-06, Model 1903A3, is an American clip-loaded, 5-round magazine-fed, bolt-action service rifle used primarily during the first half of the 20th century. It was officially adopted as a United States military bolt-action rifle on June 19, 1903, and saw service in World War I. It was officially replaced as the standard infantry rifle by the faster firing semi-automatic 8 round M1 Garand starting in 1937. However, the M1903 Springfield remained in service as a standard-issue infantry rifle during World War II, since the U.S. entered the war without sufficient M1 rifles to arm all troops. It also remained in service as a sniper rifle during World War II, the Korean War, and even in the early stages of the Vietnam War. It remains popular as a civilian firearm, historic collector's piece, and as a military drill rifle. This 03-A3 is still in good shape and has a barrel marked RA 6-43. Great piece for the collector or someone wanting a nice addition for range day.
