Editor’s Note: A lawsuit has been filed against Activision Blizzard by the California Department of Fair Employment and Housing, which alleges the company has engaged in abuse, discrimination, and retaliation against its female employees. Activision Blizzard has denied the allegations. The full details of the Activision Blizzard lawsuit (content warning: rape, suicide, abuse, harassment) are being updated as new information becomes available.

The M13 is one of  Call of Duty: Warzone's tried and true weapons, offering high accuracy and an easy-to-control recoil for its operatives in Verdansk '84. While the M13 hasn't received as many changes in recent seasons of Warzone as some other weapons havethe consistency of this assault rifle is one of the reasons it remains a great option. For players new to Warzone, the M13 offers a lot of forgiveness when it comes to firing up close and at range.

For new players, the M13 is unlocked after reaching Level 39 in Call of Duty: Warzone or Call of Duty: Modern Warfare. While there are plenty of attachments that can be equipped to the M13, the best way to build this weapon is for medium- and long-range combat. Additionally, with this particular build, the M13 is a great choice in close combat thanks to its high rate of fire. Partnered with the right secondary, like Warzone's META OTs 9 SMG, the M13 is a great weapon to use in some of the best overall loadouts in Warzone Season 6.

Rebirth Island's smaller map is perfect for the M13 since tight corners and medium fights will favor those with accuracy and weapons with high rates of fire. The M13 has several attachments similar to those used on other assault rifles, but the M13's uniquely easy-to-manage recoil pattern is what sets it above most weapons in its class.

The Best M13 Loadout In Warzone (Season 6)

These are the best gun attachments Warzone Season 6 for the M13:

  • Muzzle: Monolithic Suppressor
  • Barrel: Tempus Marksman
  • Optic: VLK 3.0x Optic or Holographic Sight
  • Underbarrel: Commando Foregrip
  • Ammunition: 60 Round Mag

The Monolithic Suppressor significantly increases the range of the M13 while adding a suppressor, which hides players from enemy radar when firing. Combined with the Tempus Marksman, both of these attachments improve the M13's damage over range and bullet velocity. The VLK 3.0x Optic is the best sight available for the M13, adding enough magnification to become accurate without obstructing too much of the field of view around the scope. The Commando Foregrip removes much of the M13's horizontal and vertical recoil, and the 60 Round Mag doubles the amount of ammo the M13 has per magazine. These attachments have also been staples for the best M13 loadouts throughout Call of Duty: Warzone.

The best perks to use with the M13 are E.O.D., Overkill, and Amped. E.O.D. will drastically reduce the taken explosive damage, and Overkill allows players to pair the M13 with another primary weapon. Amped allows players to decrease their weapon readiness after a swap delay speed, allowing them to get the full benefit of equipping two primary weapons. Lastly, after Overkill has been grabbed, grabbing the same loadout with Ghost instead of Overkill will give players the Ghost perk. Players can reacquire their weapons and have all the benefits of Ghost while using two of their primary weapons in Warzone.
