Seeking a lightweight replacement for the M1 Garand and the M1918A2 BAR, The Army selected the M14 rifle in 1957. Production of the M14 rifle was halted in 1964, by which time 1,380,874 had been manufactured. The M14 7.62 mm rifle is a magazine-fed, gas operated shoulder weapon, designed primarily for semi-automatic fire. It was the standard service rifle until it was replaced in the late-1960s by the 5.56mm M16A1 rifle. At one time the standard issued rifle for Marines, the M14 is now used primarily in the Competition in Arms program, or for drill and ceremonial purposes. The M16 replaced the M14 as the Table of Organization rifle for the Marine Corps during the Vietnam War.

- M14, basically a product improved M1 Garand, performed well as a infantry rifle. The M14 had an effective range of 500 yards (460m). The M14 used a standard NATO 7.62mm cartridge in a 20-round magazine. The M14 was the standard Army infantry rifle, until replaced by the mass fielding of the M16 5.56mm rifle in 1966-1967. Some M14s were equipped with a bipod for use as a squad automatic weapons. However, the M14 displayed an erratic dispersion pattern, excessive recoil, and muzzle climb when fired as an automatic rifle.
- M14A1. The Army designed the model M14A1 to overcome these problems, but it was too light to become a truly successful replacement for the M1918 series BAR, and production was halted in 1963. The M14A1 featured a full pistol grip and a folding forward hand grip.
- M14 National Match (1959) was used in the semi-automatic mode only. The M14NM had special sight parts and barrels selected especially for accuracy.
