During 1952–53, testing proved the T48 and the T44 to be roughly comparable in performance, with the T48 holding an advantage in ease of field stripping and dust resistance, and a longer product development lead time. Thus, it was dropped from consideration in 1953. The T47 did not have a bolt roller and performed worse than both the T44 and the T48 in dust and cold-weather tests. The T44 was tested in a competitive service rifle competition conducted by the Infantry Board at Fort Benning, Georgia against the Springfield T47 (a modified T25) and the T48, a variant of Fabrique Nationale's FN FAL (from Fusil Automatique Leger, French for "light automatic rifle"). Infantry Board service rifle trials Experimental T47 rifle Refinements included the addition of a bolt roller intended to reduce friction and a straight operating rod. Though not principally designed by any single engineer, Lloyd Corbett is credited for several refinements to the T44 design. Additionally, the long operating rod/piston of the M1 was replaced by the T47's gas cut-off system. With minimal funding available, the earliest T44 prototypes used T20E2 receivers fitted with magazine filler blocks and rebarreled for the 7.62×51mm cartridge. The T44 prototype rifle was a conventional design developed at Springfield Armory as an alternative to the T47. 30 light rifle design group following the 1950 Fort Benning tests, the T25 was renamed the T47.

Harvey and Studler were then transferred to Springfield Armory in late 1945, to continuously develop the T25. Rene Studler, then serving in the Pentagon. In 1945, Earle Harvey of Springfield Armory designed an entirely different rifle, the T25, for the new T65. Garand's design, the T20, was the most popular, and T20 prototypes served as the basis for several Springfield test rifles from 1945 through the early 1950s. Winchester, Remington, and Springfield Armory's John Garand offered alternate conversions. Changes included the addition of fully automatic fire and the replacement of the eight-round en bloc clip with a detachable box magazine holding 20 rounds. Although the M1 was among the most advanced infantry rifle designs of the late 1930s, it was not without faults, as various modifications to the basic M1 were considered during the last months of World War II. The M14's development stemmed from an extensive line of experimental weapons based on the M1 Garand rifle. A new variant of the M14, the Mk 14 Enhanced Battle Rifle, has been in service since 2002. The M14 served as the basis for the M21 and M25 sniper rifles, which were eventually replaced by the M24 Sniper Weapon System. Civilian semiautomatic variants are used for hunting, plinking, target shooting, and shooting competitions. military, with variants used as sniper and designated marksman rifles, accurized competition weapons, and ceremonial weapons by honor guards, color guards, drill teams, and ceremonial guards. The M14 rifle remains in limited service across all branches of the U.S. In 1967, it was officially replaced by the M16 assault rifle, a lighter weapon with a smaller, intermediate cartridge. The M14 was the last American battle rifle issued in quantity to U.S. Army, Navy, and Marine Corps for Basic and Advanced Individual Training from the mid-1960s to the early 1970s.
