Warzone 2: The Best ISO 45 Loadout

The ISO 45 in Warzone 2 is an S-Tier SMG that draws inspiration from the real-life B&T APC45 firearm, currently holding the record for the game's most widely used close-range weapon.

Despite being a META weapon, the ISO 45 is not necessarily an easy-to-handle choice. Many players find optimizing their ISO 45 loadouts and configurations challenging in the latest season of Warzone 2. Those willing to push through these difficulties, however, will quickly find themselves with a truly powerful ISO 45 build that can make short work of those unfortunate enough to be in the line of fire.

The Best ISO 45 Attachments in Season 5

As an SMG, the ISO 45 lacks reach and recoil control. Therefore, it benefits from stability and range components such as the Bruen Pendulum muzzle, EXP Shear rear grip, and the.45 Auto Hollowpoint ammunition. The following is a complete list of the best attachments for the ISO 45 in Warzone 2's Season 5:

ISO 45 Component	Best Attachment
Muzzle	Spiral V3.5 Flash Hider
Barrel	7" EX Raptor-V2
Stock	SK-3 Cheetah
Ammunition	.45 Auto Hollowpoint
Magazine	45-Round Drum
Optic	Slimline PRO
Rear Grip	EXP Shear

The Best Loadout for ISO 45

For an accuracy-oriented loadout, players can replace Spiral V3.5 with the Bruen Pendulum muzzle, have the 9” PTX Trainer on the barrel, and use the Slimline PRO optic instead of the gun’s iron sight.

The best perks for an ISO 45 loadout are Double Time, Overkill, Fast Hand, and Ghost.

The Best ISO 45 Configuration and Class Setup

For the ISO 45’s tuning, players will need to focus on damage and accuracy. They must configure the weapon for the lowest recoil and maximum velocity to land more kills in close to mid-range combat. The following is an ideal configuration for this SMG:

Bruen Pendulum (muzzle): +0.18 → +0.15
Spiral V3.5 Flash Hider (muzzle): -0.60 → +0.30
7" EX Raptor-V2 (barrel): -0.22 → -0.22
9" PTX Trainer (barrel): +0.10 → +0.00
SK-3 Cheetah (stock): -1.00 → +1.55
.45 Auto Hollowpoint (ammunition): +0.60 → +9.00
Slimline PRO (optic): -1.80 → -2.20
EXP Shear (rear grip): -0.35 → -0.24

Pairing the ISO 45 with the TAQ-V is an excellent idea as it allows players to handle close to long-range battles with little hassle.

How To Unlock The ISO 45 SMG

Warzone 2 players can unlock the ISO 45 in Season 5 by getting 45 no-hit SMG kills. In the DMZ mode, however, they must escape the battlefield while equipped with this weapon to have it unlocked.
