The ISO is a close-range Modern Warfare SMG that is fairly underrated. In the right circumstances and with the correct attachments, it can absolutely shred from up close in the form of the best Warzone ISO loadout.

SMGs have been pretty viable during Warzone’s lifespan. From the MP5 to the Cold War Mac 10, players have been utilizing their fast fire rate to dominate close-range engagements.

Way back in Modern Warfare’s fifth season, the ISO SMG dropped as a new weapon. Now, in Warzone Season 3, the weapon is still a great close-ranged option, taking down enemies very quickly in close combat. Here’s how to maximize its potential with attachments.

Best Warzone ISO loadout attachments

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

The best ISO loadout starts with the FSS Nightshade barrel, as not only does this provide the weapon with a suppressor and boosts damage range, recoil control, and bullet velocity.

The ISO Collapsible and Tac Laser are useful for mobility, increasing movement speed, and aim down sight speed. Further, the 50 Round Drums is also vital for performance because of the fast fire rate, allowing players to maintain the rate of fire for much longer.

The Merc Foregrip is great for some recoil control, and even though this weapon isn’t great at range, it still helps with controlling the weapon when you need it.
