The US Army is looking for an upgrade to the M249 squad automatic weapon, a mainstay of the infantry squad and its prime source of firepower.
According to a notice on the government’s Federal Business Opportunities website, first spotted by Army Times, the US Army is looking for the Next Generation Squad Automatic Rifle, or NGSAR, to replace the M249.
The NGSAR “will combine the firepower and range of a machine gun with the precision and ergonomics of a carbine, yielding capability improvements in accuracy, range, and lethality.”
The notice stipulates that NGSAR proposals should be lightweight and compatible with the Small Arms Fire Control system as well as legacy optics and night-vision devices.
“The NGSAR will achieve overmatch by killing stationary, and suppressing moving, threats out to 600 meters, and suppressing all threats to a range of 1200 meters,” the notice states.
The FBO posting does not list a calibre for the new weapon. The M249 fires a 5.56 mm round, and the Army is currently examining rounds of intermediate calibre between 5.56 mm and 7.62 mm to be used in both light machine guns and the eventual replacement for the M4 rifle.
The desire to replace the 5.56 mm round comes from reports indicating it is less effective at long range, as well as developments in body armour that lessen the round’s killing power.
The M249’s possible replacement, the M27 infantry automatic rifle, has already been deployed among Marines and is now carried by the automatic rifleman in each Marine squad.
The M27 was first introduced in 2010, originally meant to replace the M249, but the Marine Corps is reportedly considering replacing every infantryman’s M4 with an M27.
The notice also requires that the NGSAR come with a tracer-and-ball ammunition variant, which “must provide a visual signature observable by the shooter with unaided vision during both daylight and night conditions.”
The NGSAR should also weigh no more than 12 pounds with its sling, bipod, and sound suppressor. The M249 weighs 17 pounds in that configuration, according to Army Times. The notice does not include ammunition in its weight requirements.
The phasing in of M249 replacement should take place over the coming decade, the notice says.
