The latest Modern Warfare 3 Aftermarket part is now available and it looks and sounds like a part you'll want to add to your collection.

The JAK Scimitar Kit takes one of MW3’s newer weapons and makes it potentially even more powerful and deadly. Here’s how to unlock it to add it to your collection.

The JAK Scimitar Kit is an aftermarket part conversion kit for the FJX Horus SMG that offers "improved range and recoil" and "also unlocks the use of a large capacity drum magazine" for the weapon.

To unlock the JAK Scimitar Kit, you’ll need to complete five weekly challenges from Season Four, Week Three in MW3. These challenges can be completed in MW3 multiplayer, Zombies, or Warzone, and five from the full list will do the trick.
