After the M14's adoption, Springfield Armory began tooling a new production line in 1958, delivering the first service rifles to the U.S. Army in July 1959. However, long production delays resulted in the 101st Airborne Division being the only unit in the army fully equipped with the M14 by the end of 1960. The Fleet Marine Force finally completed the change from M1 to M14 in late 1961. Springfield Armory records reflect that M14 manufacture ended as TRW, fulfilling its second contract, delivered its final production increment in fiscal year 1965 (1 July 1964 – 30 June 1965). The Springfield archive also indicates the 1.38 million rifles were acquired for just over $143 million, for a unit cost of about $104.
