What do MW3 Aftermarket Parts do?

MW3’s Aftermarket Parts are attachments linked to the loadout’s Conversion Kit section that can enhance specific attributes of a particular gun or entire weapon category or completely alter both the functionality and appearance of a chosen gun.

These include greatly improving weapon stats such as range, damage, and recoil control, transforming weapon category, converting an Assault Rifle into a powerful SMG or heavy LMG, and providing better sight or mobility with specific accessories like Optics or Stocks.

Why are MW3 Aftermarket Parts important?

Aftermarket Parts have become an important feature due to the impact they have on MW3’s meta weapons. Some of them can even turn underrated weapons into meta contenders or popular picks.

Most AMPs have been overpowered upon release and even required several nerfs to balance them. They grant the game’s weapons a fresh perspective. Since the game’s launch, we’ve seen a ton of underrated weapons become meta picks, with AMPs either notably improving overall stats, transforming the weapon category, or offering cleaner sight options.

All in all, that’s everything you need to know about MW3’s Aftermarket Parts. For more on the game, be sure to check out our other guides:
