M14 rifle, officially the United States Rifle, 7.62 mm, M14, is an American selective fire automatic rifle that fires 7.62×51mm NATO (.308 Winchester) ammunition. It gradually replaced the M1 Garand in US Army service by 1961 and in US Marine Corps service by 1965. It was the standard issue infantry rifle for U.S. military personnel in the Contiguous United States, Europe, and South Korea from 1959 until it was replaced by the M16 rifle in 1970. The M14 was later used for U.S. Army, Coast Guard and Marine Corps basic and advanced individual training from the mid-1960s to the early 1970s. The rifle remains in limited front line service within all branches of the U.S. military as an accurized competition and sniping weapon. It is also used as a ceremonial weapon by honor guards, color guards, drill teams, ceremonial guards, and the like.
