The military may be interested in other calibers, but the US Army has just awarded FN America a big contract to crank out thousands of M4’s chambered in good ol’ 5.56 over the next five years.
As the Defense Department has announced:
FN America LLC, Columbia, South Carolina, was awarded a $119,216,309 firm-fixed-price contract for M4/M4A1 carbine. Bids were solicited via the internet with six received. Work locations and funding will be determined with each order, with an estimated completion date of Jan. 30, 2025. U.S. Army Contracting Command, New Jersey, is the contracting activity (W15QKN-20-D-0006).
All those rifles will be produced in FN’s South Carolina manufacturing facility which should be humming for the foreseeable future.
