If you’re looking for a new submachine gun to use in Warzone 2, then the new ISO 9mm should be in your view.
If you’re interested in seeing what it’s all about, Call of Duty expert FaZe Booya on YouTube has you covered. He recently shared a video going over the best ISO 9mm loadout.
The best ISO 9mm loadout to dominate your Warzone 2 lobbies
FaZe Booya believes the new ISO is better than the previous ISO 45 “because this one has the 9mm ammo that’s easier to control, you can have a little more range, and it’s got a faster fire rate.”
He throws the 9mm Hollow Point rounds into the gun and tunes for damage range and bullet velocity to give the SMG an extra kick.
For the rear grip he opts for the EXP Shear, which gives more speed to sprint-to-fire and aim-down-sight. He tunes the attachment to further improve both of those stats.
In terms of the stock, it’s the Demo Fade Tac tuned for aim walking speed and sprint speed.
He throws the Slimline Pro in the optic slot, which he also tunes for aim-down-sight speed to go with the precision sight picture.
FaZe Booya’s best M13C loadout:
| SLOT | ATTACHMENT | TUNING (VERTICAL, HORIZONTAL) |
| Optic | Slimline Pro | -3.00, 0.00 |
| Stock | Demo Fade Tac | -4.00, -2.40 |
| Rear Grip | EXP Shear Grip | -1.00, -0.45 |
| Ammo | 9mm Hollow Point | +0.70, +9.00 |
| Mag | 5o round drum | N/A |
