The 5.56 round is based on the real world 5.56×45mm NATO cartridge. It was developed for the American AR-15 rifle, later the M16 and several variants, during the Vietnam war in the 1950s, derived from the .223 Remington rifle round. The 5.56x45mm round also replaced the 7.62x51mm round’s role as NATO’s standard rifle cartridge. While it offers higher muzzle velocity, less weight, and less recoil, it also has a much lower muzzle energy and low penetration than the 7.62x51mm NATO.
