More work, changes and an opticīeyond the new caliber and weapon design, more ­options will be available to shooters. There is not a follow-on M27 ­replacement in the works other than Marine Corps monitoring of the NGSW program, Flynn said. The Corps’ M27 IARs will reach the service life ­limit by 2031. When asked about work with the NGSW and ­fielding plans, Marine Corps Systems ­Command spokeswoman Kelly Flynn said the Corps, “­continues to assess NGSW solutions for maturity, suitability and affordability to meet our operational requirements.” The 10-year contract for the weapon has allotted 120,000 rifles or automatic rifles for the Army but has capacity to build another 130,000 for Marines, SOCOM and foreign partner sales, officials said. Marines and Special Operations Command troops participated in testing and evaluating the NGSW prototypes. In 2010, the Corps began fielding the M27, a 5.56 mm infantry automatic rifle, to replace both the SAW and M4. The Marine Corps found its own commercial replacement for the M4, at least for infantry and reconnaissance Marines, in recent years. 30-caliber ammunition left over from World War I drove budget-conscious arms developers to choose the. The M1 Garand rifle, fielded to troops in World War II was first built in both. But rather than go with a commercial round, the Army chose instead to produce its own projectile, based on work done by engineers and shooters at the Army ­Marksmanship Unit. 264 USA rounds as ­contenders, Army Times reported in 2017. That study, began in 2014 and published in 2017, resulted in the Army choosing to look for its ­replacement in the 6 mm range.Įarly experiments included the. troops ­complained about the 5.56 mm caliber’s limited range, which prompted development and fielding of an improved 5.56 mm round in 2010.Īdvances in body armor that could withstand the 5.56 mm round eventually pushed researchers to launch the Small Arms Ammunition ­Configuration Study. None of those long gun programs succeeded.Įarly in the Afghanistan War, U.S. Those included the early 1980s advanced combat rifle program, the early 2000s objective individual combat weapon, or XM29, and a subsequent ­program known as XM8, which had opticsīuilt into the weapon. Over the decades, multiple ­programs sought to replace the M16 and its later carbine variant, the M4. military, NATO and at least 85 countries fielded the M16. The Army selected Sig Sauer to build its Next Generation Squad Weapon rifle and automatic rifle, both shown here. Leaders also saw a chance for better accuracy because of the reduced recoil. Shooters claimed that lighter rounds lacked “­stopping power,” an elusive metric for determining a round’s effectiveness.īut advocates pushed for a lighter round that would add more shots and give a greater volume of fire. The Army adopted the M16A1 in 1967 to replace the 7.62 mm M14 rifle.Ĭontroversy centered around the performance of lighter rounds when compared with heavier rounds. It was a shift that stopped the use of the heavier ­.30-caliber family ammunition common among ground combat troops beginning in World War I.ĭeveloped in the late 1950s by Eugene Stoner, the M16 rifle was first fielded by the Air Force. The caliber was used within small game hunting ­circles and was a major departure for small arms. The historyįrom its inception, the 5.56 mm round and the M16 service rifle were controversial. Combinations of bullet, powder and cartridge configuration and small items on the weapon could be adjusted as the Army fits the ammo and weapon together in the manufacturing. The final weapon design and ammunition features are still being refined.ĭue to federal contracting rules, Army entities such as Program Executive Office Soldier andĪrmy ­Futures Command were restricted from detailed ­contact with the vendors during prototype selection, said Bridgett Siter, CFT-SL spokeswoman. “The effects achieved by the NGSW system on first round hits would likely take our current weapons multiple rounds to achieve,” Siter wrote.
