Today’s guide goes in-depth and looks at the Bruen Mk9 Best Attachments & Class Setups. We break down weapons stats such as damage, rate of fire, and recoil.

The Bruen Mk9 graced Modern Warfare with the release of Season 3. It is touted as a high accuracy and reliable damage Light Machine Gun.

The guide provides the three most efficient class setups based on the objective of the player. For example, we provide a long-range and a close-range loadout. These are made to fully utilize the weapon’s capabilities.

Without further ado, let’s get into the Bruen Mk9 Best Attachments & Class Setups guide.

Weapon background

The Bruen Mk9 is based on the M249 SAW which has appeared in many past Modern Warfare titles including COD4, MW2, and MW3. 

The weapon is and always was known for its fast fire rate with the trade-off of low/medium damage.


Players can unlock the Bruen MK9 by getting 3 kills when the enemy is near smoke using an LMG in 15 different matches.


  • Damage: 34 – 24
  • Rate of Fire: 759RPM
  • Recoil: Vertical(sways to the left slightly)

From the stats above we can see that the Bruen Mk9 will kill in 3 shots if all shots land in the upper torso/ chest area. The weapon has the same rate of fire as the Holger-26. However, it has a slightly higher damage range meaning it has the potential to 3 shot an enemy if all shots land on target.

Best Attachments

The best attachments for the Bruen Mk9 in Modern Warfare are the:

  • Bruen 18”0 Para Barrel
  • Stippled Grip Tape
  • 60 Round NATO 5.56 Mag conversion kit

The Para Barrel combined with the Stippled Grip Tape drastically speeds up the weapons ADS and movement speed.

The 60 Round Mags add a host of benefits to this LMG including advanced ADS speed, sprint to fire, and movement speed. It also drastically speeds up the weapons reload speed which is one of the weapon’s main downfalls.

Best Class Setups

Here are the best loadouts for the Bruen Mk9. We have created 3 loadouts based on different playstyles and objectives. Check it out below.
