September 15, 2023: Season 6 is on the horizon and we've adjusted the best Warzone MX9 loadout along with the best attachments to use.

The best Warzone 2 MX9 loadout remains an underrated option as the attention turns towards the launch of Season 6. With recent weapon buffs and nerfs spicing up the Warzone meta, this particular SMG is a solid choice.

Featuring an impressive rate of fire and controllable recoil pattern, it's surprising not to see the MX9 up there as one of the best SMGs but with such stiff competition, it often flies under the radar.

Before we take a closer look at the best MX9 loadout, check out our other guides showcasing the best ranked play loadouts and when the next double XP event is taking place.

What is the best Warzone 2 MX9 loadout?

  • Barrel: 16.5" Bruen S901
  • Laser: 1mW Quick Fire Laser
  • Magazine: 32 Round Mag
  • Rear Grip: Bruen Q900 Grip
  • Comb: FTAC C11 Riser

This particular build impacts levels of handling but the additional damage range and accuracy guarantee high levels of performance in those competitive mid-range engagements.

With a bit of trigger discipline, it's possible to use the MX9 at longer distances but even with minimal damage drop-off, it's more suited to close-range combat.

Best Warzone 2 MX9 attachments

The Warzone 2 gunsmith contains a wide range of attachments that are capable of transforming any weapon to suit any style of play. After spending a bit of time testing and tweaking various combinations, we've settled on a set of five that has all the key ingredients to achieve plenty of wins.

  • Barrel: 16.5" Bruen S901
  • Laser: 1mW Quick Fire Laser
  • Magazine: 32 Round Mag
  • Rear Grip: Bruen Q900 Grip
  • Comb: FTAC C11 Riser

Up first is the 16.5" Bruen S901 which provides major boosts in damage range and bullet velocity. When engaging in a mid-range gunfight, the Bruen Q900 Grip comes with extra recoil control to ensure the bullets hit the target every single time.

How to unlock MX9 in Warzone 2

The MX9 is part of the Bruen platform meaning the unlock method of the SMG is slightly different than other weapons in the arsenal. To get your hands on the SMG, you'll need to use another weapon.

In the case of the MX9, level up the STB 556 assault rifle to level 13 to unlock it. To do this as fast as possible, we recommend using a double weapon XP or making the most of a future double XP weekend.

Best Warzone 2 MX9 perk package and equipment

Once the best MX9 attachments are ready for battle, searching for a perk package and equipment combination that provides extra damage and additional protection is the next step in building the strongest loadout. Here are our recommendations.

Perk package

  • Base: Double Time
  • Base: Bomb Squad
  • Bonus: Fast Hands
  • Ultimate: High Alert

For maximum awareness, High Alert comes into its own. As soon as an opponent has clocked your position, your vision will pulse and allows you to reposition before the enemy has a chance to eliminate you.


  • Semtex (Lethal)
  • Smoke Grenade (Tactical)

Is the MX9 good in Warzone 2?

The MX9 has all the ingredients needed for players to make an impact in mid-range engagements. The extra damage and recoil control provided by the above attachment combination means it's very easy to score plenty of kills over the course of a match.
