Recommended attachment setup to equip on the Bruen Mk9 LMG in Modern Warfare 3

Our goal with this loadout is to turn the naturally heavy and sluggish LMG into something that feels more like an Assault Rifle without compromising its raw power and range. Here’s the breakdown of the best attachments for your Bruen MK9:

Attachment Choice Reason
Muzzle Colossus Suppressor Makes you undetectable on enemy radar, keeping you off their minimap while firing the weapon. Also reduces both vertical and horizontal recoil by -6%.
Underbarrel DR-6 Handstop A mobility-focused underbarrel that boosts Aim Walking, ADS, Sprint to Fire, and Movement Speeds.
Optic Slate Reflector / Mk.3 Reflector Optics are subjective, but these are two of the cleanest sights in MW3. Choose what feels comfortable for you.
Magazine 60 Round Mag Lighter mag, lighter LMG. This attachment significantly improves handling and mobility without compromising firepower. Besides, 60 rounds should be more than enough!
Rear Grip STIP-40 Grip Enhances Recoil Control and Gun Kick Control, ensuring your shots stay accurate at longer ranges. Keep that beast under control!
