m1903 springfield
The Springfield M1903 (United States Rifle, Caliber .30-06, Model 1903) is an American bolt action rifle built on the Mauser action, fed with an internal 5-round magazine. It was designed in 1903 and mainly manufactured by Springfield Armory.
It was used by US forces, most notably during the Two World Wars, Korean War, and Vietnam War for limited sniper role. The weapon is recognizable by its straight grip stock, Type C semi-pistol grip stock (M1903A1 variant), bent bolt handle, oblong stock indentation on some models, and an adjustable flip-up rear sight or aperture one (M1903A3).
