This would be my choice during WWII.
M-1903A4 (1942) was a M-1903A3 specially modified for use as a sniper rifle with the addition of a M73 or M73B1 2.2X telescope. The M1903A4 had a full pistol grip stock. The M1903 was an accurate rifle with an effective range of 600 yards (550m). The M-1903A4 was used during World War II, playing a part in the Normandy invasion in June 1943, until the M-1C and M-1D model Garand replaced it. The M-1903A4 was also used to a very limited extent during the early years of the Vietnam war.
