Best ISO 45 loadout in Warzone

Warzone has an incredibly diverse gun arsenal and with newer updates introducing even more weapons to the game and switching up the previously existing meta that once dominated. One of the most popular games in Warzone is the ISO 45, a fan-favourite in the SMG weapon class.
How to unlock the ISO 45 Assault Rifle in Warzone 2?
In order to use the ISO45 in Warzone 2, players will need to either extract the weapon in MW3 Zombies or manage to secure 45 Operator kills without taking any damage using SMGs in any of MW3 or MW2 multiplayer modes.
Best loadout for ISO 45 in Warzone

Its popularity can be attributed to its lethality in close-proximity gunfights and its capability for spray-and-pray tactics. However, it tends to be less effective at mid- and long-range engagements. Furthermore, the lack of an efficient recoil system prompts the type of attachments best suited to be included in ISO 45 loadout as discussed in the guide below.
• Barrel: 7" EX Raptor-V2
• Muzzle: Spiral V3.5 Flash Hider
• Magazine: 45-Round Drum
• Rear Grip: EXP Shear
• Stock: SK-3 Cheetah
As opposed prioritizing a much lethal ammunition style such as 5.56 High Velocity in Modern Warfare III’s multiplayer game mode, a higher magazine capacity has proven to be more effective in Battle Royale game mode. This effect is pronounced in Warzone 2 primarily due to the accuracy falloff at a longer range being greater and also the lack of immediate respawn, except in Resurgence mode, and having a greater consequence to dying.
The rationale behind each attachment is straightforward; the Spiral V3.5 Flash Hider, 7" EX Raptor-V2 Barrel, and EXP Shear Rear Grip enhance damage range while stabilizing recoil and improving hip-fire accuracy. These attachments also facilitate boost in mobility, and sprint-to-fire speeds which helps maximize the capabilities offered by SMGs.
While the ISO 45 loadout is widely regarded as optimal for Warzone 2 gameplay, personal preferences may influence its performance. If any feature of the loadout feels counterintuitive to your style of gameplay, consider adjusting it using in-game sliders or substituting attachments to tailor the loadout to your liking.
FAQs
Is the ISO 45 good in Warzone?
Yes, the ISO 45 is a strong and popular SMG in Warzone. It delivers fast fire rate, solid mobility, and excellent close-range damage. With the right attachments, it performs as one of the best short-range weapons, though its recoil requires a bit of control for accuracy.

How to test guns in Warzone?
To test weapons, load into DMZ or a private match. Equip your chosen gun and attachments, then test it at different ranges—close, medium, and long. Check recoil, bullet spread, and damage output. Use targets or walls to trace recoil patterns, then fine-tune attachments for better control or mobility. Testing helps you find what suits your aim and sensitivity best.
