After its Season 4 introduction and explosion in popularity, Call of Duty’s developers took it upon themselves to nerf the ISO 45 and curb its insane trajectory. You can still make it a close range behemoth though, so here are the best ISO 45 loadouts for Warzone and Modern Warfare 2.
Best Warzone ISO 45 Build
Described by Activision as a fast-firing SMG that’s perfect for room-clearing, we were stunned at the ISO 45’s TTK in the immediate aftermath of Season 4. So were the devs, apparently, because it’s close range damage and hipfire accuracy were both hit hard in Season 4 Reloaded’s weapon changes.
It’s still strong up close, so we’re opting to boost its accuracy and range to make sure it can cope in Warzone’s bigger open spaces. The 9″ PTX Trainer and Lockgrip Precision-40 both come in to stabilize shots and improve damage range (albeit bringing a slight decrease to handling).
Similarly, the 45 Round Drum and EXP Shear will minimize reloads and speed up ADS respectively, ensuring your ISO is snappy and quick. It’ll mean you can challenge opponents who catch you unawares when you’re clearing those rooms and running-and-gunning.
- Underbarrel: Lockgrip Precision-40
- Magazine: 45 Round Drum
- Barrel: 9″ PTX Trainer
- Stock: SK-3 Cheetah
- Rear Grip: EXP Shear
Finally, the SK-3 Cheetah makes the cut to improve your mobility, letting you walk and move much faster. It makes you a harder target when engaging enemies and ensures it’s easier to hit all your shots.
If you’re struggling to control its bounce, you can throw on the A30 Stout as your Rear Grip. This’ll improve your recoil control. Bear in mind though – the ISO 45 is only really suited to close ranges.
Best Loadout for MW2
In Modern Warfare 2, the ISO 45 again thrives at the closest of ranges. It’s really geared towards running-and-gunning: a playstyle we’ve leaned right into with our chosen attachments.
The SK-3 Cheetah and EXP Shear translate over to keep the ISO 45 as responsive and easy to use as possible. There’s also not quite as much need to augment range and damage in MW2, with the majority of your engagements likely to happen at closer-ranges than in Warzone.
As a result, we’re swapping the 9″ PTX Trainer barrel for the lighter and faster 7″ EX Raptor-V2, as well as bringing the VLK LZR 7MW into the equation.
- Underbarrel: Commando Foregrip
- Laser: VLK LZR 7MW
- Barrel: 7″ EX Raptor-V2
- Stock: SK-3 Cheetah
- Rear Grip: EXP Shear
Lastly, the Commando Foregrip makes our recommended MW2 build for the benefits it brings to handling and aiming idle stability, slightly less punishing than the Lockgrip Precision-40. It’s a formidable loadout built for speed, damage and devastation.
Those are the best ISO 45 loadouts for Warzone and Modern Warfare 2. Despite its nerf, it’s among the best SMGs in both titles, so use it while it’s still hot (if not as sizzling as it once was).
