Season 6 of Call of Duty: MW2 & Warzone 2 has arrived with a few new weapons including an assault rifle and a submachine gun. The ISO 9mm is a new SMG that you may unlock from the battle pass, and it dominates fights at close range. This is a fast-firing SMG with easy to control recoil, making it a top competition for meta submachine guns likeISO 45andFennec 45. Here are the best loadout and attachments for ISO 9mm in Warzone 2.

Bes ISO 9mm SMG Loadout and Class in Warzone 2 & MW2

These are the attachments I use while playing battle royale and DMZ with the ISO 9mm SMG. Remember, this is a weapon most powerful at close range, so you’ll need to focus on HIP fire accuracy, recoil smoothness, and ADS speed. If you want to equip a scope, swap out the Laser for anAim OP-V4 Optic.

Alternatively, if you want a stock attachment, swap the magazine to attach theRES 2Stock.Similarly, theVLK LZR 7mwis a staple Laser attachment you can use as an alternative to the Quick Fire Laser. I prefer to use a Barrel and Muzzle combination with this SMG to improve its damage range and steadiness. The16″ XLB-SBarrelis another top choice to use instead of the ISO 45 Factory attachment.

How to unlock the ISO 9mm submachine gun in Warzone 2 & MW2

you’re able to unlock the ISO 9mm Submachine Gun in Warzone 2 & MW2 from the Season 6 Battle Pass. To unlock this gun, you need to progress toSector F7in the Battle Pass. This can be done quickly by using the battle tokens to claim adjacent sectors. I’d recommend unlockingSector F1, F2, andF3to easily progress toF7.

Once you’ve unlocked the weapon, jump into battle royale, multiplayer, or DMZ to level up the ISO 9mm SMG. My recommendation would be to grind small MP maps likeShipmentwith Weapon XP tokens activated. This is the quickest method to unlock all the attachments for this powerful SMG.
