Army Lt. Col. Andrew Lunoff, product manager for the service’s small caliber ammunition program, said that the round currently under consideration is the 6.8mm caliber.
Lunoff was speaking on a panel on intermediate caliber development at the annual National Defense Industrial Association Armaments Systems forum here.
The 6.8mm round is the offspring of a project formerly known as the Enhanced Rifle Cartridge Program that put together Special Operations Command, the Army Marksmanship Unit and Remington Arms to create an alternative to the 5.56mm round currently in use across the force.
