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.
