Best Warzone ISO 9mm attachments

Thanks to the gunsmith, there's a huge range of Warzone attachments capable of transforming the ISO 9mm to suit all kinds of playstyles. After a few hours of mastering the SMG, we've settled on this combination to excel in close-range combat:

• Muzzle: Spiral V3.5 Flash Hider
• Laser: VLK LZR 7mW
• Stock: Res 2
• Rear Grip: EXP Shear
• Magazine: 50 Round Drum

The Spiral V3.5 Flash Hider kicks things off by hiding excess muzzle flash and providing some much-needed recoil steadiness.

The trio of the VLK LZR 7mW, Res 2 stock, and EXP Shear provide huge improvements in aim-down sight speed and sprint-to-fire time, guaranteeing fast reaction times whenever an opponent moves into the crosshairs.

Last and by no means least is the 50 Round Mag. The ISO 9mm goes through bullets extremely quickly and with plenty ready to fire, it's very easy to eliminate multiple opponents without having to dip out of the action and reload.

Best Warzone ISO 9mm perks and equipment

After equipping the very best Warzone ISO 9mm attachments, finding a perk package and two pieces of equipment is the next step to assembling the very best loadout for battle royale action. Here are our recommendations for the opening weeks of Season 6:

Perks

• Base: Overkill
• Base: Bomb Squad
• Bonus: Fast Hands
• Ultimate: Ghost

Overkill grants you the ability to use two primary weapons in the same loadout. We recommend pairing the ISO 9mm with the Kastov 762 assault rifle which still holds its own despite receiving a nerf.

Bomb Squad increases resistance to incoming explosives which can be the difference between surviving a grenade or an unexpected visit to the gulag. Next is Fast Hands which allows you to swap between your weapons as fast as possible.

Lastly, Ghost conceals your location from airborne UAVs which is incredibly useful during the final stages of a match.

Equipment

• Lethal: Semtex
• Tactical: Smoke Grenade

It's hard to go wrong with a Semtex grenade when it comes to dealing some additional damage to nearby opponents and vehicles. Pairing them with a Smoke Grenade allows you to create chaos with anyone trying to use them as improvised cover or as a distraction to escape a sticky situation.

Is the Warzone ISO 9mm meta?

At the time of writing, the ISO 9mm has slotted into the meta thanks to its impressive firepower and high mobility levels. We'll have to wait and see if Raven Software decides to apply further balancing changes to bring it in line with the rest of the SMG category. For now, it's definitely worth using in casual, ranked, and Resurgence matches.
