The M14 rifle, formally the United States Rifle, Caliber 7.62 mm, M14, is an American
selective fire battle riflefiring 7.62x51mm NATO ammunition. Although largely superseded in military use by the M16 rifle, it remains in limited front line service with the United States Army, Marine Corps, and Navy. The M14 also provides the basis for the M21 and M25 sniper rifles. It was the last so-called "battle rifle" (a term applied to weapons firing full-power rifle ammunition) issued in quantity to U.S. troops, and was also the shortest-lived service rifle in the history of the U.S. arsenal.
The M14 was developed from a long line of experimental weapons based upon the M1 Garand. Although the Garand was one of the most advanced
infantry rifles of the 1940s, it was not a perfect weapon. Modifications were beginning to be made to the basic M1 rifle's design since the twilight of the Second World War. Changes included adding fully automatic firing capability and replacing the 8-round "en bloc" clips with a detachable box magazine holding 20 rounds. Winchester, Remington, and Springfield Armory's own John Garandoffered different conversion designs. Garand's design, the T20, was the most popular, and T20 prototypes served as the basis for a number of Springfield test rifles from 1945 through the early 1950s.
Earle Harvey of Springfield Armory designed a completely different rifle, the T25, for the new .30 Light Rifle cartridge. The latter was based upon .30-06 cartridge case cut down to the length of the
.300 Savagecase. The .30 Light Rifle eventually evolved into the 7.62x51mm NATOand the commercial .308 Winchesterround. In the background, Lloyd Corbett was tasked with developing .30 Light Rifle conversions for the M1 rifle and later the T20 prototypes. After a series of prototype designs, the T44 surfaced. The earliest T44 prototypes used the T20 receivers rebarreled for 7.62 mm NATO, and replaced the long operating rod/piston of the M1 with the T25's shorter "gas expansion and cut-off" system. Later T44 prototypes used newly fabricated receivers shorter than either the M1 or T20; the new action's length was matched to the shorter 7.62 mm NATO cartridge instead of the longer .30-06. The T44 competed successfully against the T47 (a modified T25) and the FN FAL(T48). This led to the T44's adoption by the U.S. military as the M14 in 1957. Springfield Armory began tooling a new production line in 1958 and delivered the first service rifles to the U.S. Army in July 1959. However, long production delays resulted in the 101st Airborne Divisionbeing the only unit in the Army fully equipped with the M14 by the end of 1961. The Fleet Marine Forcefinally completed the change from M1 Garand to M14 in late 1962.
The rifle served adequately during its brief tour of duty in Vietnam. Though it was unwieldy in the thick brush due to its length and weight, the power of the 7.62 mm NATO cartridge allowed it to penetrate cover quite well and reach out to extended range, developing 2,470 ft·lbf (3,350 J) of muzzle energy. However, there were several drawbacks to the M14. The traditional wood stock of the rifle had a tendency to swell and expand in the heavy moisture of the jungle, adversely affecting accuracy. Fiberglass stocks were produced to resolve this problem. However, the rifle was discontinued before very many could be distributed for field use. Also, because of the M14's powerful 7.62x51 mm cartridge, the weapon was virtually uncontrollable in fully automatic mode. The M14 was developed as a means of taking the place of four different weapons systems — the M1 Garand, the M1 Carbine, the M3 "Grease Gun" and the
M1918 Browning Automatic Rifle(BAR). It was thought that in this manner the M14 could simplify the logistical requirements of the troops if it took the place of four weapons. Although it proved to be an impossible task to replace all four, the weapon excelled as a replacement for the M1 rifle, fixing many of the previous rifle's shortcomings. The cartridge was too powerful for the submachine gunrole and the weapon was simply too light to provide as a light machine gunreplacement for the BAR. The M60 machine gunbetter served this task.
The M14 remained the primary infantry weapon in Vietnam until it was replaced by the M16 in 1966–1969. The M16 was ordered as a replacement for the M14 by direction of
Secretary of Defense Robert McNamara, over the objection of those Army officers who had backed the M14 (other factions within the Army research and development community had opposed the M14 and the 7.62x51 mm round from the start). Though production of the M14 was officially discontinued, some disgruntled troops still managed to hang on to them while deriding the M16 as a frail and underpowered " Matteltoy" or "poodle shooter". In January 1968 the U.S. Army designated the M16 as the "Standard A" rifle, and the M14 became a "Limited Standard" weapon. The M14 rifle remained the standard rifle for US Army Basic Training until 1970.
Uses of M14 in U.S. service since M16 replacement
Although the M14 was phased out as the standard-issue rifle in the 1960s, M14 variants are still used by various branches of the US Military as well as other armed forces, especially as a sniper rifle and as a
designated marksman rifle, due to its excellent accuracy and effectiveness at long range. Special active units such as the OPFORunits of the Joint Readiness Training Centeruse M14s. Few M14s were in use in the Army until the Afghanistan and Iraq Wars. Since the start of these conflicts, many M14s have been employed as designated marksman and sniper rifles. These are not M21 rifles, but original production M14s. Common modifications include scopes, fiberglass stocks, and other accessories. [cite web|url=http://www.rand.org/pubs/conf_proceedings/CF162/CF162.appn.pdf |title=CF-162.appn.part1 |date= |format=PDF |accessdate=2008-09-08] In the mid-1990s, the USMC chose a new rifle for DM use, an M14 modified by the Precision Weapons Shop in Marine Corps Base Quanticocalled the Designated Marksman Rifle (DMR). It is intended for use by security teams (SRTs, FAST companies), and USMC Scout Snipers in the cases where a semi-automatic rifle would be more appropriate than the standard bolt-action M40A1/A3 rifle. The USMC Rifle Team uses the M14 in shooting competitions.
The 1st Battalion of the
3rd United States Infantry Regiment( The Old Guard) in the Military District of Washingtonis the sole remaining regular United States Army combat field unit where the M14 is still issued as the standard rifle, along with a chromed bayonet and an extra wooden stock with white sling for military funerals, parades, and other ceremonies. The United States Air ForceHonor Guard uses a version of the M14 specially modified by the USAF Gunsmith that prevents semi-automatic fire; members have to manually cycle a new round by pulling on the charging handle every time they fire. The United States Navy Ceremonial Guard and Base Honor Guards also use the M14 for 3-volley salutes in military funerals. It is also the drill and parade rifle of the United States Military Academy, United States Naval Academy, United States Air Force Academy, The Citadel, Norwich University, Virginia Military Institute, and North Georgia College and State University.

These sniper variants have probably been replaced by the Mk 11 Mod 0, selected in 2000. SEALs also use the Mk 14 Mod 0 EBR (Enhanced Battle Rifle) for close-quarters battle and in a designated marksman role.
U.S. Navy ships carry several M14s in their armories. They are issued to Sailors going on watch out on deck in port. The M14 is also used to shoot a large rubber projectile to another ship when underway to start the lines over for alongside refueling and replenishment.
Although a very secretive unit, the "
Delta Force" is known to have used M14 sniper variants. According to "", the well-known account of the Battle of Mogadishu, at least one of the "D-Boys", Sergeant First Class Randy Shughart, used an M14 for sniping from helicopters to provide support fire to ground troops. His M14 was probably fitted with an Aimpoint 3000 sight.Fact|date=June 2007
The Special Forces ("Green Berets") have made some use of the XM25 "spotter rifle". The XM25 was developed in the late 1980s within the
10th Special Forces Group, which was charged to support Special Forces sniper weapons as well as the Special Operations Target Interdiction Course (SOTIC). The XM25 was first planned as a replacement for the old M21, but after the Army adoption of the M24 SWS as its standard sniper rifle, the M25 was intended to be used by spotters of the sniper teams, while the snipers would use the bolt-action M24. Tests had shown that the M24 and M25 have the same precision when using the same M118 ammunition.
Though the M14 has remained in service longer than any U.S. infantry rifle with the exception of the Springfield M1903 rifle, it also holds the distinction of serving as the standard infantry rifle of the U.S. Army for a shorter span of time than any other weapon.
Commercial and non-U.S. use
M14 production tooling was sold in 1967 to the Taiwanese, who in 1968 began producing their Type 57 Rifle. The State Arsenal of the Republic of China produced over 1 million of these rifles from 1969 to the present under model numbers of M305 and M14S.
The Philippine government issues M14 rifles, as well as M1 carbines, M1 Garands and M16s, to their civilian defense forces, including the Civilian Auxiliary Forces Geographical Unit (CAFGU) and Civilian Volunteer Organization (CVO). The Greek Navy is also a user of the M14.
Norincoand Poly Technologieshave produced M14s in the past and had been exported to the United Statesprior to the enactment of the Violent Crime Control Act.

The purpose-built National Match version was produced in 1962 and 1963 by Springfield Armory, and in 1964 by TRW. Springfield Armory upgraded a number of service-grade rifles in 1965 and 1966 to National Match specifications. Upgrading was also carried out in 1967 at the
Rock Island Arsenal. These M14 variants are to this day capable of extreme long-range accuracy.
Springfield and TRW delivered more than 11,000 National Match rifles in the 1962–1964 period.Roughly 8,000 service rifles were modified to NM standards during 1965–1967.

M14M (Modified)/M14NM (National Match)
*The M14M is a semi-automatic only version of the standard M14 and was developed for use in civilian rifle marksmanship activities such as the
Civilian Marksmanship Program.
*M14M rifles were converted from existing M14 rifles by welding the select-fire mechanism to prevent full-automatic firing.
*The M14NM (National Match) is an M14M rifle built to National Match accuracy standards.
*The M14M and M14NM rifles are described in a (now-obsolete) Army regulation, AR 920-25, "Rifles, M14M and M14NM, For Civilian Marksmanship Use," dated 8 February 1965. Paragraph 2, among other things, stated that the Director of the Alcohol and Tobacco Tax Division,
Internal Revenue Service, Department of the Treasury (predecessor to the Bureau of Alcohol, Tobacco, Firearms, and Explosives) had ruled that M14M and M14NM rifles so modified would not be subject to the 1934 National Firearms Act(NFA) and, as such, could be sold or issued to civilians. However, with the passage of the Gun Control Act of 1968, the NFA was amended to prohibit sales of previously modified automatic weapons such as the M14M and M14NM to civilians.
*"Stand-off Munition Disruption", used by Explosive Ordnance Disposal personnel to destroy unexploded ordnance.
*Essentially an M14 National Match rifle with scope.
Mk 14 Mod 0 EBR
*Shorter, more tactical version of the M14, with a retractable stock and multiple rails for more accessories.
*Modified designated marksman version of the M14, used by the USMC.
*Variant designed by La France Specialties of San Diego, California, and produced by Smith Enterprise of Tempe, Arizona.
*The prototype actually used the M60 machine gun parts for the gas system; however, production models had the system custom-manufactured so the rate of fire could be controlled.
Stamped into receiver heel:
*Springfield Armory (or commercial contractor name)
The M14 rifle was first furnished with a walnut stock, then with birch and finally with a synthetic stock. Original equipment walnut and birch stocks carry the Department of Defense acceptance stamp or cartouche (an arc of three stars above a spread-winged eagle). These stocks also carried a proof stamp, a P within a circle, applied after successful test-firing.
Rifles manufactured through late 1960 were provided with walnut handguards. Thereafter synthetic, slotted (ventilated) hand guards were furnished but provedtoo fragile for military use. These were replaced by the solid synthetic partstill in use, usually in dark brown, black or a camouflage pattern.
Right-hand twist, 1:12 inches, 4 grooves
Although M14 rifle production ended in 1964, the limited standard status of the weapon resulted in the continued manufacture of accessories and spare parts into the late 1960s and beyond.
