Short-Range M13B Best Loadout

For our first loadout, we went with a low-weight M13B with a lower range and then coupled it with another primary weapon with a longer range. It gave us the best of both worlds. We were able to couple it with a Sniper Rifle that allowed us to deal good damage even at long range. Using the high Fire Rate of the gun, we made it lightweight and further increased its Fire Rate.

As our attachments focus on increasing the M13B stability and somewhat decreasing its weight, we went with the attachments shown above.

Secondary Weapon

Now you might have noticed that we haven’t done much about the range of the M13B. That is because the loadout is designed so that you can use a Marksmen Rifle or a Sniper Rifle as the secondary weapon. Now you’re open to numerous options for the loadout, but the one that we believe is perfect for the current loadout is Signal 50.

Now before you start to question that the Signal 50 in Call of Duty Warzone 2.0 isn’t fit for the M13B class loadout or whatever, hear us out first. We have selected certain attachments that ensure that we’ll get the best out of the gun. So, without further ado, here are the attachments for our Secondary Weapon Signal 50 Loadout.

For the secondary weapon, the Signal 50, we got these attachments.

  • Barrel: 29” TV Kilo-50
  • Rear Grip: SA Finesse Grip
  • Laser: FSS OLE-V
  • Muzzle: Nilsound 90 Silencer
  • Stock: SO Inline Stock

For the Perk Package, we have to go with the Weapon Specialist Package. The main reason is that its first Base Perk will help us carry two Primary weapons at once. So we have to utilize it to the best of our abilities.


Stun GrenadeClaymore

Stun Grenade is good Tactical Equipment. When fired, it will stun in front of the enemy, giving you a bit of an advantage. Using the M13B’s high fire rate is all you’ll need to make a difference in the fight. Throw it at an enemy, and watch them trying to get away from you. You’ll have a small window of opportunity, so you’ll have to utilize it and get the best out of it.

The best Lethal Equipment for the loadout is none other than the Claymore. You can place it at a strategic position, such as an entrance to your sniping spot, and when the enemy comes, they’ll get knocked out quickly. So you won’t be getting any surprises. Not only that, you can place it while the enemy is chasing you. They won’t even see it and get killed.

Long Range M13B Best Loadout

Now for the Second Loadout in COD Warzone 2.0, we gave the M13B a bit of range by giving it a long-range barrel. Not only that, we paired it with a larger magazine to ensure that the high Fire Rate doesn’t empty the magazine quickly. The magazine and the Barrel affected its mobility and handling, so we decided to pair it with a Pistol.

For a longer range and more bullets in the magazine, here are the attachments that we selected.

Secondary Weapon

The Secondary weapon of the M13B loadout needs to be a solid weapon of Call of Duty Warzone 2.0. One on which we can rely on the battle and that it can take out opponents quickly, like the M13B. For that, there is no other choice as good as the X13 Auto. It is an automatic Pistol that does good damage at a shorter range.

So if you aren’t comfortable with the M13B in the short range, then the X13 Auto is your best bet. Whereas if you are okay with using the M13B in the short range, you can switch to X13 Auto and finish the fight instead of reloading your gun. It gives you too much room for making plays.

For the secondary weapon attachments, we got the following.

  • Barrel: Impact Point
  • Magazine 33 Round Mag
  • Laser: FJX DOID-70
  • Rear Grip: Cronen Lima-6
  • Stock: XRK Bar Stock

Perk Package

The Perk Package that we chose for our Loadout is Warden Package. Now the Warden Package is designed with a few things in mind. It is designed to ensure that you’ll have good mobility and handling of weaponry.


Flash Grenade Frag Grenade

Flash Grenade in COD Warzone 2.0 is the best option for Tactical Equipment in the current loadout and class of the M13B. You’ll have to perfect using the Flash Grenade to ensure that you can get benefits out of it. 

Now, what is the best item in Lethal Equipment than the Frag Grenade? Almost all of the FPS players know how the Frag Grenade works, so using it is fairly easy.

Unlocking M13B In Warzone 2.0

We conclude our loadout to the M13B in COD Warzone 2.0. You have to remember, and you can’t just go and make a loadout of the M13B out of the blue. You’ll have to unlock it. But the unlocking experience isn’t something that you’ll usually find in the game. It is a unique experience, at least for us. For that, you’ll have to play a specific game mode and there kill one specific mini-boss to unlock the M13B. And here’s how you do it.

First of all, you will have to get to the DMZ mode in Warzone 2.0. Now it is a unique mode, where you’ll have to go in there and successfully get out of the game through one of the three exfil spots in the map. So, here’s what you need to do.

As you Enter the DMZ, your goal will be to go to the Radiation Zone. It will be marked with a Hazard sign in a yellow circle. In that Radiation Zone, you need to find a target who is known as the Chemist. Your goal will be to defeat the Chemist, pick up his special M13B, and get out of the game using an Exfil. But that isn’t going to be easy. You’ll have to come prepared as he isn’t easy to defeat.

Final Thoughts

The M13B is a great gun to make loadout in Call of Duty Warzone 2.0. But that doesn’t that everything will go great with it. A good loadout needs to be carefully selected to ensure that you’re getting the best out of the gun. We have prepared two different loadouts that fit different use cases of the gun. Whether you want it as a long-range gun, just add a long barrel. If you want to use it as a support weapon for a longer-range weapon, take out some of its weight, and you’ll have better mobility.

Whichever of these loadouts of M13B you choose for COD Warzone 2.0, you’ll get the best experience out of it. That means you’ll have the opportunity to use it in different scenarios, where it is quite fun to test out new things. Anyways, check out these loadouts and let us know what you think about them.
