M14 rifle

The M14 rifle is an American selective fire automatic rifle that fires 7.62×51mm NATO ammunition. It became the standard issue U.S. rifle in 1959, replacing the M1 Garand, and was itself largely replaced by the M16 rifle in the mid-1960s due to the M16's lighter weight, smaller caliber ammunition, and perceived better suitability for the changing nature of warfare.

The M14 was derived from the M1 Garand, incorporating features such as a shorter barrel, a fully automatic fire selector, a 20-round magazine, and an improved gas system. It was intended to be a versatile weapon, capable of serving as both a rifle and a light machine gun.

Despite its short service as the standard issue rifle, the M14 saw extensive use in the Vietnam War. It was lauded by some for its accuracy and stopping power, particularly in open terrain. However, it was also criticized for its uncontrollable full-automatic fire, its length and weight, and its susceptibility to malfunctions in the humid jungle environment.

The M14 was officially replaced by the M16 in 1968, but it has continued to see limited use in various roles. The U.S. military still uses accurized M14 variants for designated marksman and sniper roles, as well as for ceremonial purposes. The M14 has also been adopted by numerous other countries and continues to be manufactured and used worldwide. The Enhanced Battle Rifle (EBR) is a modern upgrade of the M14, featuring a more ergonomic stock and various mounting options for optics and accessories.
