Call of Duty: Warzone's evolving seasons demand fresh Assault Rifle strategies. Our top MK9 loadout delivers precision, extended range, rapid fire rate, and high-capacity magazines—everything for battle royale dominance.
This Warzone-optimized MK9 setup boosts damage per second at medium-to-long ranges while staying agile up close. Drawing from extensive Season 4 testing, here's the premier MK9 build post-launch.

Best MK9 Loadout in Call of Duty: Warzone
The MK9, a new Season 4 addition alongside the C58 and Nail Gun, joins Warzone and Black Ops: Cold War as a formidable LMG. With its blistering fire rate and manageable recoil, it shines at mid-range thanks to solid damage output. Here's the proven setup:
Muzzle: Monolithic Suppressor
Barrel: Summit XRK 26.8″
Laser: Tactical Laser
Optics: VLK 3.0x Optic or Corio Eagleseye 2.5x (adapt for preference)
Ammunition: 60 Round Mags

The Monolithic Suppressor, a staple from Modern Warfare, boosts range and suppresses sound across compatible weapons. Paired with the Summit XRK 26.8″ barrel, it enhances velocity without excessive weight. Add a rear grip for extra stability—mobility dips slightly, but recoil vanishes for laser-like control.

The 5mW Laser activates on ADS for pinpoint hip-fire accuracy, ideal for this rapid-fire LMG. Swap in Fast Mag for quicker reloads, prioritizing speed over max capacity on this beast.
Once loaded, drop a second loadout with a powerhouse primary. Pair via Overkill perk with Warzone's best sniper to cover all ranges.
