The M4 and M4A1 carbines are the Army's primary individual combat weapons.
"It is a great honor to be awarded this contract from the United States Army," said John Day, vice president, Remington Defense Division.
"Our workforce is extremely proud to be adding this combat-proven carbine to the Remington Defense family alongside our combat-proven sniper rifles, suppressors and shotguns.
"We will produce these carbines with the same diligence, attention to detail and quality that snipers and shooters worldwide expect from Remington."
The Army placed an initial order under the contract for 24,000 M4A1 carbines, which are being produced to the Army's M4 technical data package specifications. Deliveries will begin in September 2013, Remington said.
Remington said the M4 and M4A1 carbines will be produced at a manufacturing facility in New York.
