The M1 Garand (officially the United States Rifle, Caliber .30, M1) was the first semi-automatic rifle to be generally issued to the infantry of any nation. In 1936, it officially replaced the bolt-action M1903 Springfield as the standard service rifle of the United States Armed Forces and was subsequently replaced by the selective-fire M14 in 1957. However, the M1 continued to be used in large numbers until 1963 and to a lesser degree until 1966.
