5.56mm

5.56 millimeter, also known as 5.56mm (Green) in the game, is a type of Ammunition currently used by six Weapons. The power of 5.56mm is on par with 7.62mm (Blue) Ammunition. but usually considered slightly better. All guns in surviv.io that use 5.56mm ammo are quite reliable and are typically used throughout a game.



Trivia

 * The 5.56mm projectiles are green-colored.
 * The ammo is based on the 5.56×45mm NATO cartridge, as all 5.56mm weapons in the game use that cartridge in real life.
 * The QBB-97 is an exception, as although the version in-game is an export variant that uses 5.56×45mm NATO, non-export versions use its own 5.8×42mm ammo.
 * The 5.56mm casing is shown with a rim, even though the real-life cartridge is rimless.
 * This is the first new type of ammunition added to the game- originally, surviv.io only had 9mm, 7.62mm, and 12 gauge.
