The Army has selected 6.8mm as the new common round for both its Squad Automatic Weapon and M4 replacement.

A Prototype Opportunity Notice posted on the government website fbo.gov is going to give three companies the chance to submit their versions of the new individual service rifle, the Next Generation Squad Weapon, chambered in 6.8mm, the same round that developers are using for the Next Generation Squad Automatic Rifle program.

Until recently, officials would only say that developers were being encouraged to look at requirements in the intermediate caliber range, somewhere between the existing 5.56mm and 7.62mm rounds common to individual, sniper and machine guns in the Army’s inventory.

Until recently, the goal was to first develop the NGSAR and then allow its advancements to inform the development of the M4 replacement, the NGSW-Rifle.
