Recently, FN announced that NATO accepted and standardized FN’s 5.7x28mm cartridge for its standard small arms portfolio. This puts FN in rare company of having a cartridge standardized to be used by NATO forces and allies. The new 5.7x28mm cartridge joins 9x19mm, 5.56x45mm, 7.62x51mm, and .50 BMG as standardized ammunition used by NATO.
