If you’re looking for the best SMG in Warzone Season 6, then you’ve come to the right place. We’ve ranked every SMG from worst to best and even picked out the best loadout class for each to give you an edge.

The best SMGs in Warzone can give you a huge advantage in close-quarter firefights, especially when you kit them out with meta attachments. While SMGs may not offer the range or accuracy of the game’s deadly Assault Rifles, they do give players the tools needed to get plenty of kills.

This hyper-aggressive playstyle may not be for every player, but having an SMG you can rely on in Season 6 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 Season 6, we’ve ranked all the best SMGs and the attachments you should be using with them.

20. ISO

Getting kills with the ISO will likely prove difficult.

Best ISO Warzone loadout

  • Barrel: FSS Nightshade
  • Laser: 5mW Laser
  • Stock: ISO Collapsible
  • Underbarrel: Merc Foregrip
  • Ammunition 50 Round Drums

The ISO is arguably the most frustrating SMG to use in Warzone. Not only does this gun produce nothing but hitmakers, it also tears through its ammunition incredibly fast. Even with the 50 Rnd Drums, you’ll constantly find yourself reloading after and during every firefight or kill.

While its rate of fire may seem fast, this pint-sized SMG does literally nothing with it. In fact, you’re often better off clobbering your opponent or picking up the closest piece of floor loot. There really is no reason as to why anyone would want to use the ISO.


19. KSP 45

KSP 45 Warzone
The burst fire nature of the KSP 45 can make it rather unwieldy.

Best KSP Warzone loadout

  • Muzzle: Agency Suppressor
  • Barrel: 10.5″ Task Force
  • Underbarrel: Field Agent Foregrip
  • Ammunition: Salvo 48 Rnd Fast Mag
  • Rear Grip: Speed Tape

Like the majority of Warzone’s burst fire weapons, the KSP 45 has struggled to make a name for itself in the frozen fields of Verdansk. While it may blend both AR and SMG playstyles together, its methodical 3-burst firing pattern keeps the KSP from competing against its rapid-fire counterparts.

Even with the added bullet velocity from the Agency Suppressor and 10.5″ Task Force, this SMG still struggles to deliver the speed needed to take down multiple foes in close-quarter fights.

18. Striker 45

Striker 45 SMG
The Striker 45 remains one of the most unpopular SMGs in Warzone.

Best Striker Warzone loadout

  • Muzzle: Monolithic Suppressor
  • Barrel: 400 mm Stainless Steel
  • Laser: Tac Laser
  • Underbarrel: Merc Foregrip
  • Ammunition: 45 Round Drum Mags

Despite having decent range potential, the Striker 45 is outclassed by many of the best Warzone SMGs. There’s just no reason as to why you’d want to utilize this weapon unless you’re trying to complete in-game camo challenges.


If you’re not put off by the Striker 45’s lackluster close-quarters damage, then the build above will help you squeeze out a few kills. You’ll definitely struggle to beat the likes of the MAC-10 and MP5, but the added range could keep you from biting the bullet early.

17. P90

P90 Warzone
The P90 is capable of dishing out some decent damage.

Best P90 Warzone loadout

  • Muzzle: Monolithic Suppressor
  • Barrel: FORGE TAC Retribution
  • Laser: TAC Laser
  • Stock: Fly Strap Stock
  • Rear Grip: Stippled Grip Tape

Unlike the other SMGs on the list, the P90 is actually capable of taking down mid-range targets. Its high rate of fire and minimal recoil will keep your shots accurate, while also keeping you competitive in close-quarter environments. 

The P90 remains an underrated gun that rarely sees play across Verdansk. However, if you’re willing to try out another SMG, then you might find some luck with this classic Modern Warfare SMG.


16. Uzi

The Uzi combines great mobility that is marred by the Uzi’s poor damage.

Best Uzi Warzone loadout

  • Barrel: Monolithic Suppressor
  • Barrel: FSS Carbine Pro
  • Stock: Forge TAC Ultralight
  • Underbarrel: Merc Foregrip
  • Ammunition:.41 AE 32-Round Mags

The Uzi received an increase in play in Warzone Season 3, back when it was introduced as floor loot. Since then, this iconic weapon has rarely made it out of the custom loadout screen.

Arguably the strongest part of the Uzi is its fantastic mobility, which allows players to aggressively rush down their opponents. This is particularly useful if you enjoy going for sneaky flanking maneuvers or wish to simply keep on the move. It’s just a shame the damage potential is fairly low.

15. PP19 Bizon

PP19 Warzone
The PP19 may lack the power of the top picks, but it does have a little extra range.

Best Bizon Warzone loadout

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

The PP19 Bizon became a common site 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, the PP19 Bizon does offer some decent mid-range options. Of course, hip-fire is the main priority with this build, but Monolithic Suppressor and 8.7” Steel barrel can give you that little bit of extra range damage when you need it. 

14. TEC 9

TEC9 loadout
The TEC 9 SMG is deadly in close-quarter fights.

Best TEC 9 Warzone loadout

  • Muzzle: Full Auto Repeater
  • Barrel: 4.9” Task Force
  • Laser: Tiger Team Spotlight
  • Stock: Raider Stock
  • Ammunition: STANAG 48 Rnd

Unlike other Warzone SMGs, the TEC 9 enables players to swap out muzzles to change the gun’s fire rate from burst to fully automatic. This means you can kit it out for a little range or fully commit to close-quarters fights.

While the TEC 9 may look small and unimposing, the Cold War SMG is capable of dishing out incredible amounts of damage. The added mobility also makes you incredibly quick on your feet, enabling you to aggressively flank your foes.

13. Fennec

Fennec SMG in Warzone
Activision / Infinity Ward
This SMG is lethal at catching your enemies in close-quarter fights.

Best Fennec Warzone loadout

  • Barrel: ZLR 18″ Deadfall
  • Laser: Tac Laser
  • Perk: Slight of Hand
  • Underbarrel: Operator Foregrip
  • Ammunition: 40 Round Drum Mags

Featuring a vast array of features that makes this gun a perfect choice for any run, the Fennec is a fantastic choice to utilize in your Season 6 loadouts.

Able to tear through multiple enemies at once, the recoil pattern, rate of fire, and exceptional hip-fire will see you through any sticky situation. These attachments will only take this already phenomenal gun further into beast mode.

12. CX-9

CX-9 Warzone loadout
Treyarch / Activision
The CX-9 is one of the newer SMGs added to Warzone.

Best CX-9 Warzone loadout

  • Muzzle: Monolithic Suppressor
  • Underbarrel: Commando Foregrip
  • Stock: CX-FR
  • Perk: Sleight of Hand
  • Ammunition: 50 Rnd Drum

This punchy SMG offers great mobility, lightning-fast fire rate, fantastic close-quarters damage, and an insanely quick reload. The CX-9 was originally meant to be released in Modern Warfare, but the gun was never officially added to the game until now.

While the CX-9 may not be as competitive as its Cold War counterparts, this punchy SMG has quickly risen through the ranks and has found a spot within the top 10. In fact, a number of streamers like FaZe Swagg have been demonstrating just how deadly it can be.

11. LC10

Activision / Treyarch
The LC10 has great mobility and accuracy.

Best LC10 Warzone loadout

  • Muzzle: Agency Suppressor
  • Barrel: 13.9” Task Force
  • Stock: Raider Stock
  • Ammunition: STANAG 55 Rnd
  • Rear Grip: SASR Jungle Grip

The LC10 features fantastic accuracy, great mobility, decent close-quarters damage, and a high fire rate. To top things off this pint-sized SMG also has fantastic handling, which makes gunning for those all-important headshots a breeze.

Having an SMG that also has little extra range damage can also help secure more kills when you’re low on AR ammo or scrambling for your primary.

10. AUG

AUG Warzone loadout
Modern Warfare’s AUG is fully-auto and performs more like an AR than an SMG.

Best AUG Warzone loadout

  • Muzzle: Monolithic Suppressor
  • Barrel: 622mm Long Barrel
  • Laser: Tac Laser
  • Underbarrel: Merc Foregrip
  • Ammunition: 5.56 NATO 60-Round Drums

While Modern Warfare’s AUG had a brief stint in the meta spotlight, it was quickly overshadowed by Warzone’s best Assault Rifles. Despite this, the reliable SMG boasts decent accuracy and range, making it an incredibly versatile option.

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 this a great mid-range option.

9. AK-74u

The AK-74u has risen in popularity.

Best AK74u Warzone loadout

  • Muzzle: GRU Suppressor
  • Barrel: 10.3″ Task Force
  • Stock: Spetsnaz PKM Stock
  • Underbarrel: Spetsnaz Grip
  • Ammunition: 40 Rnd Drum

The AK-74u has always been a reliable choice among SMG enthusiasts. This deadly weapon rewards hyper-aggressive plays, while also giving players tremendous amounts of accuracy. To make matters even better, the AK-74u also has a fairly decent damage range.

The AK-47’s sibling may have dropped a few places since the last update, but don’t be surprised if you see this build continue to crop up across Verdansk in Season 6.

8. MP7

MP7 Warzone
The MP7 delivers incredibly accurate hip fire.

Best MP7 Warzone loadout

  • Muzzle: Monolithic Suppressor
  • Barrel: FSS Recon
  • Underbarrel: Merc Foregrip
  • Ammunition 60 Round Mags
  • Perk: Slight of Hand

A lot more MP7 loadouts have started to crop up across Verdansk and while it may not deal as much damage as the MP5, it is still a worthy choice. Unlike most guns in Modern Warfare, the MP7 delivers highly accurate hip fire, making it great for those moments where you don’t have time to ADS. 

Whether you’re tired of using the MP5 or just want to melt squads with the hip fire, then the MP7 is a great choice. 

7. Milano 821

Warzone Milano loadout
Activision / Treyarch
The Milano has quickly risen up the rankings.

Best Milano Warzone loadout

  • Muzzle: Sound Suppressor
  • Barrel: 10.6” Task Force
  • Stock: Raider Stock
  • Underbarrel: Foregrip
  • Ammunition: STANAG 55 Rnd Drum

Following the Season 4 weapon nerfs, the Milano still continues to climb its way up the SMG rankings. In fact, top Warzone players like Aydan have been showcasing just how deadly this pint-sized SMG can be.

Not only are there several builds that favor close-quarter engagements, there are a number of loadouts that also dish out great damage in mid-range firefights. This makes the Italian SMG more versatile than most weapons in its class.

6. MP5

MP5 Warzone
Activision / Infinity Ward
The MP5 still takes the crown for the best SMG.

Best MP5 Warzone loadout

  • Barrel: Monolithic Integral Suppressor
  • Stock: FTAC Collapsible
  • Underbarrel: Merc Foregrip
  • Ammunition: 45 Round Mags
  • Rear Grip: Stippled Grip Tape

It should come as no surprise that the MP5 is one of the top picks. In fact, this snappy SMG has remained popular since Warzone’s launch. Its high fire rate and incredible damage make it a great choice for close-quarters firefights. 

This loadout is one the fastest in the entire game, allowing players to quickly sweep corners and flush out any pesky campers. Consider using this loadout to supplement your favorite Assault Rifle class to ensure you’re dealing as much damage as possible. 


PPSH Warzone loadout
Activision / Treyarch
This particular PPSH build is incredibly potent.

Best PPSH Warzone loadout

  • Muzzle: GRU Suppressor
  • Barrel: 15.7″ Task Force
  • Stock: Raider Stock
  • Underbarrel: Spetsnaz Grip
  • Ammunition: 55 Rnd Drum

Warzone’s Season 3 update brought with it the PPSH. This iconic WWII SMG comes packed with an incredible rate of fire and has barely any recoil when kitted out with the best attachments. While the gun’s damage per shot may be on the low side, its rapid-fire and large ammo capacity enable players to quickly chew through many a foe.

Simply attach the Gru Suppressor, Spetsnaz Grip, and 50 Rnd Drum and you have an SMG that is capable of some truly devasting things. It’s certainly not hard to see why the PPSH has quickly risen through the rankings.

4. Cold War MP5

This MP5 build is lethal in short-range gunfights.

Best Cold War MP5 loadout

  • Muzzle: Agency Suppressor
  • Laser: Tiger Team Spotlight
  • Stock: Raider Stock
  • Underbarrel: Brusier Grip
  • Ammunition: STANAG 50 Rnd

The Cold War MP5 plays very similarly to its Modern Warfare counterpart. However, it does come packed with a higher rate of fire and increased TTK, meaning you can absolutely melt foes in close-quarter firefights.

This current build is purely focused on making the MP5 as quick and reactive as possible. After all, mobility is imperative in Warzone, particularly when you wish to aggressively rush your foes and eliminate them in late-game rounds.

3. Bullfrog

Activision / Treyarch
The Bullfrog can barrage foes with a never-ending hail of bullets.

Best Bullfrog Warzone loadout

  • Muzzle: GRU Suppressor
  • Barrel: 7.4” Task Force
  • Laser: Tiger Team Spotlight
  • Stock: KGB Skeletal Stock
  • Underbarrel: Bruiser Grip

The Bullfrog’s massive magazine and decent range damage make this Cold War SMG incredibly viable. This deadly gun has recently overtaken both the MAC-10 and MP5, making it one of the most popular SMGs in Warzone.

After all, having to constantly reload can lead to some rather frustrating deaths. Fortunately, the Bullfrog gives you enough rounds to down multiple foes in just a single magazine. Simply hold down the trigger in close-quarter fights and watch the bullets fly.

2. MAC-10

Mac 10 warzone
Activision / Treyarch
This MAC-10 loadout is great for those close-quarter scenarios.

Best Mac10 Warzone loadout

  • Muzzle: Agency Suppressor
  • Barrel: 5.9” Task Force
  • Stock: Raider Stock
  • Underbarrel: Field Agent Grip
  • Ammunition: Salvo 53 Rnd Fast Mag

Despite receiving some nerfs in the Season 3 patch, the MAC-10 is a must-use in any player’s loadout. This SMG is an absolute beast, featuring an incredible rate of fire, good damage, and staggeringly accurate hip fire. While the MP5 dominated the top pick for SMGs for so long, this gun has quickly overtaken the previous fan favorite.

This loadout will increase the MAC-10’s attributes even further, streamlining the spray-and-pray-type recoil with the Patrol Grip and Agency Suppressor. With a slightly increased shot distance from the 5.3″ Extended barrel, you’ll still be in a spot to be able to pick off foes from a distance.

1. OTs 9

OTs 9 Warzone loadout
The OTs 9 packs a mean punch in Warzone Season 4.

Best OTs 9 loadout

  • Muzzle: GRU Suppressor
  • Barrel: 8.1” Task Force
  • Laser: Tiger Team Spotlight
  • Stock: KGB Skeletal Stock
  • Ammunition: VDV 40 Rnd Fast Mag

This lightning-fast SMG may be the new kid on the block, but that hasn’t stopped it from proving popular amongst both casual and competitive players alike.

The build above dominates Warzone lobbies in Season 6 and many players have been using it to shred through the competition. With its incredible accuracy and added damage range, it’s not hard to see why this SMG has crept into the top-place position.

So, there you have it, the best SMGs in Warzone ranked. We’ll be updating this list over time, so be sure to check back here for all the latest updates.
