M4A1 SMG Warzone loadout is the deadliest combination that has been ever combined. This new loadout will convert your AR into a lethal kill-hungry SMG.

The Tradition of trying out different attachments on weapons in Call of Duty has been there for a very long time.

Moreover, players have been trying out unique and underused attachments since the expansion of Warzone beyond Call of Duty: Modern Warfare.

Some of these unique builds have converted pistols into deadly SMGs while some of them have removed hipfire from the face of the game.

However, the newest, unique, and absolutely ridiculous loadout combination is converting everyone’s favorite assault rifle M4A1 into the deadliest SMG in Warzone.

This weird and not so regular loadout was first put out by Call of Duty YouTuber Metaphor who threw on the barely used 9mm Para magazine to make it a bit of a close-range beast.


The YouTuber also warns players that although this loadout does make M4A1 an absolute beast in close range, but it will be a bit “atrocious” to use this in a long-range fight.

On top of the unusual mag, the build uses the Corvus Custom Marksman barrel rather than the more popular Stock M16 Grenadier option. The immensely popular Tac Laser and GI Mini Reflex optics, though, both get a spot on the loadout.

  • Barrel: Corvus Custom Marksman
  • Laser: Tac Laser
  • Optic: GI Mini Reflex
  • Magazine: 9mm Para
  • Rear Grip: Stippled Grip Tape

M4A1 is one of the most used weapons in Warzone and has been ranked at number 17 on the list of most used weapons in-game.

However, it will be interesting to see how much its rank fluctuates after being used as a deadly SMG.
