The M1903-A4 was a specifically designed sniper rifle that came as a result of early U.S. combat involvement in the Pacific. There was a high demand, that could not be filled, for telescopic (sniper) rifles. The Infantry Board and the Ordanance Department conducted an evaluation and recommended that the Weaver 2.5x 330C hunting telescope be adopted for use on M1903 and M1903-A1 rifles. The rifle was officially adopted on 14 Jan 1943 as the M1903-A4 (sniper).
