The M4 is a craftable weapon that uses up to 24 5.56 rounds. It requires 30 Low Quality Metal to craft. The M4 is a very capable weapon, which makes it a highly sought after weapon. It is considered one of the end-game weapons. As of now, M4 is obtainable via loot chests that spawn in rad towns and other default in-game structures. It is best to research it, by dragging and dropping a research kit, obtained in loot chests, over it. After that you can craft it next to a workbench for 30 low quality metal. The M4 uses 556 ammo. The same ammo used by the bolt-action sniper rifle. The ammunition can be found in loot chests around the world and in order to research it, you must drag and drop a research kit over it. After that, crafting it will cost 5 gunpowder and 2 metal fragments a piece.


  • The M4 is based off of the Colt M4A1 chambered in 5.56x45mm
  • It is the left handed variant of the M4A1 model
  • Despite the M4 being a left-handed variant, it is held by the player in the right hand. The reason for this may be to show extra detail to the gunmodel.
