Standard service rifles were produced from 1959 to 1964. (TRW) would later be awarded a production contract for the rifle as well. Initial production contracts for the M-14 were awarded to the Springfield Armory, Winchester, and Harrington & Richardson. In the end, the T44 was selected over the T48/FAL primarily because of weight (the T44 was a pound lighter than the T48), simplicity (the T44 had fewer parts), the T44's self-compensating gas system, and the argument that the T44 could be manufactured on existing machinery built for the M1 rifle (a concept that later turned out to be unworkable). As a result, the T44 was ranked by the arctic test staff as decidedly superior in cold weather operation. FN engineers opened the gas ports in an attempt to improve functioning, but this caused early/violent extraction and broken parts as a result of the increased pressures. The T48 rifles received no such special preparation, and began to experience gas system problems during the trials. Springfield Armory engineers, anxious to ensure the selection of the T44, had been specially preparing and modifying the test T44 rifles for weeks with the aid of the Armory's Cold Chamber, including redesign of the T44 gas regulator and custom modifications to magazines and other parts to reduce friction and seizing in extreme cold. In December 1953, both rifles competed in the arctic rifle trials. A Newsweek article in July 1953 hinted that the T48/FAL might be selected over the T44. During 1952-53, testing proved the T48 and the T44 roughly comparable in performance, with the T48 holding an advantage in ease of field stripping and dust resistance, as well as a longer product development lead time. The T47 and EM2 were dropped from consideration in 1952. The T44 participated in a competitive service rifle competition against the Springfield T47 (a modified T25) and Fabrique Nationale's "Fusil Automatique Leger" (French for "Light Automatic Rifle"), designated T48.

Later T44 prototypes used newly fabricated receivers shorter than either the M1 or T20 the new action's length was matched to the shorter 7.62mm NATO round instead of the longer. The earliest T44 prototypes simply used T20 receivers fitted with magazine filler blocks and re-barreled for 7.62mm NATO, and replacing the long operating rod/piston of the M1 with the T25's shorter "gas expansion and cut-off" system.

After a series of prototype designs, the T44 surfaced. 30 Light Rifle conversions for the M1 rifle and later the T20 prototypes. In the background, Lloyd Corbett was tasked with developing. 30-06, the 7.62x51mm NATO round retained the same power due to the use of modern propellants. 30 Light Rifle eventually evolved into the 7.62x51mm NATO and the commercial. 30-06 cartridge case cut down to the length of the. Įarle Harvey of Springfield Armory designed a completely different rifle, the T25, for the new. 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. Winchester, Remington, and Springfield Armory's own John Garand offered different conversions. Changes included adding fully automatic firing capability and replacing the 8-round en bloc clips with a detachable box magazine holding 20 rounds. Modifications were beginning to be made to the basic M1 rifle's design since the twilight of World War II. Although the M1 was among the most advanced infantry rifles of the late 1930s, it was not a perfect weapon. The M14 was developed from a long line of experimental weapons based upon the M1 rifle. 1.2 Infantry Board Service Rifle trials.The M14 also provides the basis for the M21 and M25 sniper rifles. It was the last American " battle rifle" (a term applied to weapons firing full-power rifle ammunition) issued in quantity to U.S. The M14 remains in limited front line service with the United States Army, Marine Corps, Navy, Air Force, and Coast Guard, and is also used as a ceremonial weapon.
