The ISO 45 SMG arrived in Warzone 2 Season 4 and it had a huge impact on the meta, becoming one of the most popular weapons in the game. While nerfs in the Season 4 Reloaded patch attempted to temper the SMG's power, it remains a top-tier pick in Season 6 with a 4.6% overall pick rate.

Despite having plenty of firepower, the ISO 45 needs a meta WZ2 loadout to truly push its strengths to the limit. Luckily, we've got you covered with the best Warzone 2 attachments for the ISO 45 in the current meta so you can decimate your foes.

  • Muzzle: Spiral V3.5 Flash Hider
  • Barrel: 7" EX Raptor V2
  • Magazine: 45-Round Drum
  • Rear Grip: A30 Stout
  • Stock: Demo Fade Tac

For starters, kick off the ISO 45 build with the Demo Fade Tac stock, this will significantly improve your mobility with added aim walking and sprint speed.

Next, make sure to equip the A30 Stout rear grip and 7" EX Raptor V2 barrel, these will drastically enhance your ADS time, hip fire control, and of course, push the gun's firepower to the limit.

Following this, attach the Spiral V3.5 Flash Hider muzzle for a boost of recoil control so you're guaranteed to land your shots on target.

Round off the loadout with the 45-Round Drum to ensure you've always got plenty of ammo and can take out multiple enemies without having to waste time reloading.

  • Perk 1: Overkill
  • Perk 2: Bomb Squad
  • Bonus Perk: Fast Hands
  • Ultimate Perk: Ghost


  • Lethal: Grenade
  • Tactical: Stun Grenade

As the ISO 45 is built for close to mid-range engagements, Overkill is a must-use perk, as it gives you access to a second primary. You can choose any weapon you'd like, but it's key it can perform at long range, so we recommend a meta weapon like the TR-76 Geist or Kastov 762.

Next, run Bomb Squad to give you a huge amount of protection from killstreaks and Fast Hands so you can quickly switch to your AR.

In terms of your Ultimate perk, Ghost is always a solid meta choice as it keeps you off opponents' radars and UAVs.

Finally, finish off the class with a Stun Grenade to throw out before a push and a Grenade for forcing enemies out of cover.

How to unlock ISO 45 in Warzone 2

In order to unlock the ISO 45 SMG in MW2 and Warzone 2, you'll need to get 45 Operator kills without taking any damage using SMGs. This requirement may be a challenge for some, but well worth it.

If you're looking for an alternative option to the ISO 45, you can't go wrong with the classic Lachamnn Sub. This gun is an all-around powerhouse and is capable of performing in any situation, which makes it perfect for solo-carrying matches.

Solid mobility, damage, and stability make this an ideal choice for Ranked, so consider testing it out if you're looking to rack up more SR.

Of course, if you're looking for a loadout that is unmatched in the firepower department then the akimbo FTAC Siege may be the perfect solution and luckily, WhosImmortal has provided the best setup.

So, there you have it, that's the best ISO 45 loadout in Warzone 2's current meta. Be sure to check out our Warzone 2 homepage for all of the latest news and guides.
