The MX9 is a hybrid SMG that will give players the edge at range in the MW2 multiplayer.

The MX9 is a SMG in Infinity Ward's latest title Call of Duty: Modern Warfare 2. Unlike other weapons in its class, the MX9 offers players greater accuracy in medium to long range engagements. Here is a quick guide on how to unlock the MX9 as well as the best attachments to use on it in MW2.

How to unlock the MX9 in MW2?

The MX9 can be quite a challenge to unlock due to the new weapon progression system Infinity Ward introduced for MW2. With this particular weapon belonging to the Bruen Bullpup platform.

In order to get the MX9 you will first need to unlock the STB 556 Assault Rifle; which you can get by reaching Level 41 in-game. Once you have gotten the STB 556 you will then need to get its' Weapon Level up to 13, which will grant you access to the MX9 receiver.

The best attachments to use on the MX9 are as follows:

  • Barrel: 16.5 STB Factory
  • Muzzle: Bruen Pendulum
  • Optic: Cronen Mini Pro
  • Comb: FTAC C11 Riser
  • Rear Grip: Bruen Q900 Grip

The MX9 is a well-balanced SMG that gives players a chance of glory in just about every kind of engagement you will come up against. While it doesn't have quite the same range capacity as the FSS Hurricane, nor the same sort of mobility stats as the Vel 46, it is a satisfactory weapon nonetheless.

With the FTAC C11 Riser comb and Bruen Q900 grip, you will have an SMG who's ADS stats are comparable to others in its' class. The Bruen Pendulum muzzle and 16.5 STB barrel, paired with the reflex sight of your choice, will increase the MX9's effectiveness in medium to long range engagements.

The only slight drawback of this weapon is it's ammo capacity; being that it only holds 25 rounds per mag, so you may find yourself running out of ammo fairly quickly. So it is with that mind that I suggest running Scavenger or a Munitions Box on your class.
