The 5.56mm cartridge is a NATO round chambered as an intermediate cartridge for the M16 rifle. It was based on the .223 Remington, with differences significant enough to adopt a new nomenclature and classification rather than a custom casing classification.
5.56mm ammo can be found both in air drops along with the M249 and the AUG A3, as well as uncommon loot around the island, with the latter typically appearing as an individual box, or several boxes found together. Individual and multiple boxes also have a chance of being found together with a 5.56mm rifle.
5.56mm ammo spawns in boxes of 30 rounds each when found as loot or from an air drop, with the exception of air drops containing the M249, where 100 to 300 rounds of 5.56mm ammo can be found with the gun.
