Call Of Duty Modern Warfare 2: Best M13B Loadout

After playing MW2 for around 100 hours here is my recommendation on M13B best loadout and class setup.

The M13B was not a part of the weapon arsenal in Call Of Duty: Modern Warfare 2 until the release of Season 1. After experimenting with the different perks and attachments on the gun, I have put together the best loadout for M13B in Modern Warfare 2.

Key Takeaways
  • Call of Duty: Modern Warfare 2 continues the tradition of allowing customizability when it comes to making weapon classes.
  • The M13B is one of the best Assault Rifles that the game has to offer.
  • With the attachments and perks we have chosen for the best M13B weapon class setup, you will be able to obliterate all the enemies that you face in Call Of Duty: Modern Warfare 2.

Author’s Note: I’ve played Warzone for over 100 hours on Steam, experiencing every mechanic and element the title has to offer.

Best M13B Class Build

For the perks and equipment for M13B, I have picked the following as the ones:

  • Basic Perk 1: Overkill or Bomb Squad
  • Basic Perk 2: Scavenger or Double Time
  • Bonus Perk: Fast Hands
  • Ultimate Perk: Ghost or Quick Fix
  • Secondary Weapon: X13
  • Tactical Equipment: Stim
  • Lethal Equipment: Proximity Mine or Semtex
  • Field Upgrade: Munitions Box or Dead Silence

As the Secondary Weapon, I’ve selected the X13 to be the best choice. The highly specialized fully automated system for triggering the X13 can fire up to twenty rounds in a second. However, it comes at the cost of less precision and range,

How To Unlock The M13B

In order to unlock the M13B for you to use, you will have to enter the DMZ and kill a boss named The Chemist. The Chemist happens to be holding the M13B hostage. The only way to unlock it for yourself is to kill the Chemist and collect the weapon from him.

Once you have taken out the Chemist, he will drop the M13B. You are to pick it up and then shoot for the extraction point. It is worth mentioning here that even if you have the gun in hand, you can still fail to unlock it should you not be able to extract it successfully. However, once you have successfully extracted the gun, you will receive a notice that you have unlocked the weapon during the mission debrief.

My Take On M13B

My Steam Profile

I personally tested out this loadout, and it packed enough power to take down 2-3 enemies in a single push. However, I did switch out the Mag and used a smaller Stock from time to time to increase mobility. The M13B has a lot of customizability, especially when it comes to the number of attachments that it boasts in Modern Warfare 2. This essentially makes this AR one of the best weapons in Modern Warfare 2.

The M13B is a perfect fit for almost any situation that the player might be in. Whether taking out an enemy from afar or for situations involving close combat, M13B will always have your back.
