M13B Assault Rifle in Warzone

Warzone’s M13B has become a popular Assault Rifle given its damage buff in Season 3 Reloaded. So, here’s every attachment, Perk, and Equipment that you need to build the best M13B loadout.

Assault Rifles remain one of the most popular picks when it comes to primary choice in Warzone. While the Season 3 Reloaded update brought a fan-favorite Advanced Warfare AR, BAL-27, some players are sticking to the ever-reliable M13B.

This AR received several buffs in the latest update, and you’ll need the best attachments, Perks, and Equipment to make it a dominating weapon choice.

With that said, here’s the best M13B loadout in Warzone Season 3 Reloaded.

Best Warzone M13B loadout attachments

  • Muzzle: VT-7 Spiritfire Suppressor
  • Barrel: 14″ Bruen Echelon
  • Optic: JAK Glassless Optic
  • Underbarrel: Bruen Heavy Support Grip
  • Magazine: 60 Round Mag

We’ll start the best Warzone M13B loadout by using the 14″ Bruen Echelon Barrel and VT-7 Spiritfire Suppressor Muzzle combo to buff the damage range, bullet velocity, and accuracy. Next, we’ll use the Bruen Heavy Support Grip Underbarrel to improve the weapon’s accuracy, stability, and gun kick control.

Then, to accurately land shots from a distance, I picked my favorite Optic, the JAK Glassless, which provides a clean sight picture. Finally, the 45 Round Mag will ensure you have enough bullets to take down multiple enemies.

Feel free to extend the Mag to the 60 Round if needed, but be aware you’re movement speed and ADS time will take a noticeable hit.

Best Warzone M13B loadout Perks & Equipment

  • Perk 1: Double Time
  • Perk 2: Mountaineer
  • Perk 3: Tempered
  • Perk 4: High Alert
  • Lethal: Semtex
  • Tactical: Flash Grenade

Coming to our choice of Perks, we opted for Double Time to make it easier for you to get around the map at a rapid pace, along with Mountaineer to reduce the damage taken when jumping from high structures.

Tempered will let you recover armor quickly, by requiring only two plates to be fully protected. Then, High Alert will let you know when an enemy spotted you from afar. As for Equipment, we picked the Semtex to deal explosive damage and the Flash Grenade so you can take foes by surprise.
