Best Bruen MK9 Warzone and Modern Warfare Loadout

The Bruen MK9, an air-cooled light machine gun, offers a solid rate of fire competing with the other weapons in its category and provides excellent stability when engaging with a target at mid to long ranges, making it much easier to control than some of its counterparts.

Once the king of Verdansk, a nerf towards the later end of the Modern Warfare season saw it fall off - but thanks to Raven Software's regular weapon tuning, the LMG is beginning to appear in the loadouts of players dropping onto Caldera and Rebirth Island.

With the best set of attachments equipped, the Bruen can easily defeat assault rifles and any kind of vehicle that may put a halt to your rampage in Verdansk or Rebirth Island.

In this guide, find the best Bruen MK9 attachments to use and the best Bruen MK9 loadout to build.

What Is The Best Bruen Warzone Loadout?

As one of the mainstays of Warzone, the Bruen is particularly strong in mid and long-distance combat. Check out the best attachments to use on the LMG in the table below.

Monolithic Suppressor
XRK Summit 26.8"
VLK 3.0x Optic
Commando Foregrip
60 Round Mags

This particular combination excels in long-distance engagements thanks to improvements in recoil and damage range. In addition, the large magazine makes it incredibly easy to eliminate multiple targets without having to reload.

Bruen MK9 Warzone Best Attachments

  • Monolithic Suppressor (Muzzle)
  • XRK Summit 26.8" (Barrel)
  • VLK 3.0x Optic (Optic)
  • Commando Foregrip (Underbarrel)
  • 60 Round Mags (Ammunition)

This set of attachments is easily the best combination we have found for the Bruen MK9.

The usual appearance of the monolithic suppressor combined with the barrel greatly increases damage range and bullet velocity, enabling you to outgun any player in a mid-range firefight.

The rest of the attachments focus on a range of elements. The laser improves aim-down sight speed, while the magazine provides extra bullets which allow you to eliminate multiple opponents without the need to reload.

Bruen MK9 Modern Warfare Best Attachments

1) Never-Ending Fire!

This class is designed to lay down a relentless wave of gunfire onto an enemy location, perfect for players that prefer to get involved in the action from afar

  •  XRK Summit 26.8” (Barrel) 
  • FORGE TAC Stalker (Stock)
  • Granulated Grip Tape (Rear Grip) 
  • 200 Round Belt (Ammunition)
  •  Merc Foregrip (Underbarrel)

Given the sheer number of bullets in the magazine, this attachment combination gives the Bruen some additional stability when opening fire on the opposition.


  • EOD (Perk 1) 
  • Restock (Perk 2) 
  • Shrapnel (Perk 3)

Selecting this perk combination is a great way to deal even more damage. EOD will protect you from explosives while Restock enables you to have your grenades resupplied over time. Shrapnel further bolsters your utility, giving you an extra piece of lethal equipment when you spawn in.


  •  Frag Grenade (Lethal)
  • Stun Grenade (Tactical)

There is nothing more satisfying than scoring a kill from a well-placed, perfectly cooked grenade. Use the frag to clear out a densely populated area of the map and use the stun to slow down enemies before you unleash the 200 rounds onto their position.

Field Upgrades

  • Trophy System

Given the lack of mobility of this loadout, it is likely that you will come under fire from a variety of lethal equipment. Place a trophy system in front of your location to prevent any enemy utility from disrupting your gameplay.


  • Cluster Strike (5 Kills) 
  • VTOL Jet (8 Kills) 
  • Chopper Gunner (10 Kills)

This combination of killstreaks can be earned extremely quickly when in the right areas of the map at the right time. Stay back and pick off enemies thanks to the range advantage to guarantee a dangerously high streak.

2) Mid-Range Menace

This loadout excels in mid-range engagements, easily dispatching of Assault Riflers and some optimistic sub-machine gunners.

  • G.I Mini Reflex (Optic) 
  • FSS Close Quarters Stock (Stock) 
  • Sleight of Hand (Perk) 
  • Stippled Grip Tape (Rear Grip) 
  • Commando Foregrip (Underbarrel)

With these attachments equipped, the Bruen heavily resembles the M249 SAW from Call of Duty 4 and just like its predecessor, the Bruen packs a heavy punch armed with attachments to provide some recoil control and a quicker aim down sight speed.


  • Double Time (Perk 1) 
  • Overkill (Perk 2) 
  • Tune Up (Perk 3)

Double time adds some much-needed mobility while overkill allows you to select a second primary weapon. We selected an MP7 for close-quarters scenarios. Lastly, tune up, increases the recharge rate of Field Upgrades, allowing you to access it much quicker than usual.


  • Proximity Mine (Lethal)
  • Smoke Grenade (Tactical)

This combination of equipment may seem strange but placing the proxy mine onto an objective and covering its location with a smoke grenade is a great way of catching out any aggressive enemies looking to grab a quick kill by charging through the cover of the smoke.

Field Upgrades

  • Dead Silence

With Double Time equipped to navigate the map faster, Dead Silence is a logical choice. Use it to flank behind the enemy without them noticing for the opportunity to score several kills in quick succession.


  • Counter UAV (4 Kills)
  • Cruise Missile (5 Kills) 
  • Wheelson (7 Kills)

Armed with the ability to play more aggressive, it is more than likely that you will have a few more deaths to your name so this killstreak combination doesn’t take much to earn but still deals a significant impact on the map.

3) Small But Mighty

The third and final loadout packs a hefty punch despite looking like extremely unassuming.

  •  Bruen 18.0” Para (Barrel)
  • No Stock (Stock) 
  • FMJ (Perk)
  • Stippled Grip Tape (Rear Grip) 
  • Tactical Foregrip (Underbarrel)

This attachment combination is a great mix of recoil control, additional mobility along with the addition of FMJ to make sure no enemy is safe even if they are hidden behind cover.


  • Quick Fix (Perk 1) 
  • Hardline (Perk 2)
  • Battle Hardened (Perk 3)

Quick Fix is a heavily underused perk. Enabling an increase in health regeneration speed, it is one of the best perks to have when in amongst the action. Hardline reduces the cost of killstreaks by one, making it easier to earn some of the higher streaks when playing aggressively and Battle Hardened increases your resistance to flash and stun grenades, allowing you to keep focused on the action taking place in front of you.


  •  Semtex (Lethal) 
  • Decoy Grenade (Tactical)

Using a Semtex instead of a frag grenade is sometimes the way to go thanks to its ability to be stuck to surfaces. The decoy grenade is the real party piece, enabling you to bait enemies easily without risking your life.

Field Upgrades

  • Stopping Power Rounds

Fancy adding an extra dose of lethality on this already powerful weapon? Of course, you do! Select Stopping Power Rounds as your field upgrade for a drastic increase in damage.


  • Precision Airstrike (5 Kills) 
  • Wheelson (7 Kills)
  • White Phosphorus (10 Kills)

This combination of streaks deals huge amounts of damage especially on the smaller maps on Modern Warfare. White Phosphorus may hinder your vision slightly due to the white smoke but with gradual damage being dealt to every single member of the enemy team making them extremely easy to eliminate, it is certainly worth the trouble of moving through the mist.
