SPRINGFIELD ARMORY M-1903
U.S. Armed Forces standard regulation rifle since 1903 (hence the name)
until the spread of World War 2 (during which, however, it was used as a
sniper rifle, due to its extreme accuracy).
Works in bolt-action, feeding from stripper clips, fires the .30 type M1903A1
Here shown with regulation WW2 sniper scope.
