The MX9 submachine gun is a 9mm conversion of the ubiquitous Steyr AUG, known in the game as the STB 556.

A small recent buff has made the gun a decent enough choice for shooters wanting a weapon chambered in subsonic 9mm ammunition, which can have better stopping power.

While it is currently outside of the absolute meta range, the MX9 can be great for close quarters in the hands of a skilled soldier. We tested it out during both the Limited Release and the current play and found this build to work!

NOTE: MWII guns have yet to receive compatibility with MWIII attachments in Warzone Mobile. We will update this page accordingly once MWIII attachments are available.

REAR GRIP: Stip-40 Grip (unlocked at level 13)

This rear grip allows for better ADS and sprint-to-fire speeds, allowing you to take advantage of the MX9’s mobility.

MUZZLE: Singuard Mk V (unlocked by leveling the VEL 46 to Level 16)

The Singuard Mk V greatly adds to increase the otherwise slow bullet velocity of the MX9, while also adding a small damage range increase and recoil control benefit, allowing you to engage enemies at various close-to-mid-range distances. 

COMB: Bruen TS-30 Comb (unlocked by leveling the HCR 56 to Level 15)

Aiming idle sway and recoil control are effectively improved by this stock choice, which allows you to stabilize the MX9.

MAGAZINE: 32 Round Mag (unlocked at Level 2)

The only magazine attachment available, the 32 round mag helps in adding more rounds for the already-dismal 25-round mag size for the MX9. 

LASER: VLK LZR 7mw (unlocked by leveling the STB 556 to level 5)

The VLK LZR 7mw ensures that your MX9 can have a faster ADS and sprint to fire speed while also providing much-needed aiming stability.

OPTIONAL REPLACEMENTS:

 

OPTIC: Cronen Mini Dot [to replace laser] 

In place of a laser, the Cronen Mini Dot can help MX9 users focusing on ADS to have a much clearer sight picture and lesser visual recoil. This can help for faster and more precise target acquisition, especially in those crucial final zones.

LASER: Point G3P-04 (unlocked by leveling up the Expedite 12 shotgun to Level 11)

The Point G3P-04 is a green hipfire-centered laser which can also help reduce the overall sprint to fire time of your MX9. This allows your build to be used effectively whenever you’re aiming down sights or firing from the hip at close quarters.

 

These attachments can help you bring the MX9 to bear in any combat situation!
