The Warzone best ISO loadouts have been around since Modern Warfare Season 5. Yet they have managed to live on in Warzoneand are proving to be a viable option for you SMG lovers out there due to its decent accuracy and fire rate. While there is plenty of competition, no less from the meta-devouring MP5, with the right Warzone best ISO loadouts and attachments, this gun can hold its own. 

Warzone Best ISO Loadouts - Speed and Slaying

Many of the high-fire-rate weapons, such as the Warzone best Fennec loadouts have sometimes struggled to sustain themselves as an alternative to the MP5, especially in close-quarters gunfights. However, the ISO may be the submachine gun that can outgun all opponents up close. Optimising the speed of the ISO will ensure that you can bounce from one fight to the next and come out unscathed, catching people off guard and gunning them down before they can fire back.

  • Barrel - FSS Nightshade
  • Underbarrel - Merc Foregrip
  • Rear Grip - FTAC Elite ISO Tape
  • Stock - Collapsible Stock
  • Optic - G.I. Mini Reflex

Here we opt for the attachment in your Warzone best ISO loadouts that will increase speed, hip fire control and accuracy up close. The FSS Nightshade keeps the weapon suppressed whilst adding to the movement speed and increasing the range. The Merc Foregrip, FTAC Elite ISO Grip, and ISO Collapsible stock all combine to increase accuracy up close, by improving the aiming movement speed, ADS time and hip-fire accuracy. Finally, an optic is preferable but could be swapped out for a 5mW Laser or Sleight of Hand. This also works nicely for the Warzone best CX-9 loadouts.

Warzone Best ISO Loadouts - Precision and Power

For a more reserved playstyle where you find players at a mid-long range in open plains, optimising the accuracy and damage range will help you with the ISO. Swapping out attachments helping with ADS and hip-fire accuracy, you will need to utilise the aiming stability and decrease any recoil over a distance.

  • Muzzle - Monolithic Suppressor 
  • Barrel - FSS Revolution
  • Underbarrel - Commando Foregrip
  • Rear Grip - FSS Vice ISO Grip
  • Ammunition - 50 Round Drums

Here we sacrifice a lot of mobility for sublime accuracy. Changing every attachment from the fast-paced loadout above, we've selected the best ISO Warzone loadout attachments that are perfect for precision and power. If you want a weapon better made for longer ranges, check out the Warzone best AN94 loadouts guide.

Starting with a longer barrel in the FSS Revolution, the Commando Foregrip, and the FSS Vice ISO Grip, all three combine to give much more control over the weapon's recoil and sway. This will allow you to remain accurate a mid-length engagement, whilst the fire rate keeps it lethal. The 50 Round Drums are very important for longer ranges as the 20 bullets that a standard clip hold makes it difficult to get more than one enemy per clip.

Warzone Best ISO Loadouts - Perks 

In addition to your attachments, it is crucial that you pair the ISO with the right perks, lethal and secondary weapon. Your secondary is preferential, however, depending on which class set-up from the above you choose, you should try and to pick a secondary which compliments it. Whilst carrying the long-ranged choice, it will be best to pair this with a submachine gun such as the MP5. If you'd prefer to run the short-ranged choice, then a sniper or a launcher may come in handy alongside it. Check out our Warzone best snipers, if you aren't sure which long-ranged weapon to pick. 

  • Perk 1 - EOD
  • Perk 2 - Overkill/Ghost
  • Perk 3 - Amped
  • Equipment - Flash
  • Lethal - C4

With this mixture, you'll have the perfect combination of mobility and stealth. Having amped will allow you to quickly change to your sniper or launcher should you need too, and the Flashbang and C4 will help you in many close gunfights, giving you that extra edge.
