The original Warzone bolsters an impressive arsenal of weapons spanning multiple categories, SMGs are no exception. So if you’re looking for the best SMGs to use in it then this is the place to be. In this guide, we ranked every Warzone SMG and picked out the strongest meta loadouts for each one.

Warzone Caldera’s close range encounters are dominated by weapons from the SMG category. But every weapon has it’s weakness, so keep an Assault Rifle in the second weapons slot for those medium range engagements.

This hyper-aggressive playstyle may not be for every player, but having an SMG you can rely on in Warzone is incredibly important. Unlike the AR class, the SMG category is not that varied, and many players often gravitate towards only a couple of picks.

Of course, that hasn’t stopped certain loadouts from cropping up. To help you increase your win rate in Warzone, we’ve ranked all the best Warzone SMGs and the attachments you should be using with them.

Remember, if you’re ready to dive into Warzone 2 and want to check out the best SMGs in the sequel to dominate Al Mazrah, be sure to check out our list of the best meta SMGs to use in Warzone 2.

  • Barrel: 8.7” Steel
  • Laser: Tac Laser
  • Stock: Corvus Skeleton Stock
  • Rear Grip: Stippled Grip Tape

The PP19 Bizon became a common sight across Verdansk when it was introduced as floor loot back in Season 4. Since then, this SMG has taken a dive in the popularity rankings.

Off meta guns aren’t exactly known for their competitive nature, however, a damage buff in the Season 2 Reloaded patch made the community start experimenting with the Bizon.

Our loadout focuses on maximizing the weapon’s damage while retaining plenty of mobility, making it a great non-meta pick for fans of Fortune’s Keep.

Best LAPA Warzone loadout

  • Ammunition: Salvo 45 Round Fast Mag
  • Laser: Tiger Team Spotlight

  • Stock: SAS Combat Stock

While the LAPA goes under the radar for a lot of players, this weapon did previously make a good sniper support weapon. This is partly down to its high ADS speed and overall mobility.

Unfortunately, it simply can’t compete with a lot of the meta options that offer a better TTK.

However, if you’re looking for a gun to pair with your 3-Line Rifle or Gorenko, this could be the perfect solution that can effectively take out enemies at close to medium range.

22. Fennec

The Modern Warfare version performs very differently when compared to its Cold War cousin. There are no burst fire rounds to be found here – instead, this variant enables players to go full-auto. If you’re after a highly mobile SMG, then you will be disappointed, but the range and accuracy do make it an underrated option.
