ISO 45: Best build for Modern Warfare 2 Season 4

The ISO 45 is a fully automatic submachine gun added in Modern Warfare 2 Season 4. If you’re looking for a top notch setup to dominate with this SMG, we’ve got what you need, here’s our best MW2 ISO 45 kit.

  • Barrel  : 16″ XLB-S
  • Laser:  1MW fast laser
  • Underbarrel Grip : Merc Forgrip
  • Rear handle:   A30 Stout
  • Magazine  : 45 rounds drum

Let’s start with our best ISO 45 gear for Modern Warfare 2, the  16″ XLB-S barrel  , which suppresses SMG shots while also increasing range, bullet speed, and recoil control. We also opted for the A30 Stout’s rear grip   for added recoil control, allowing it to stay stable at medium ranges.

Getting the first shot is very important in any combat, so we opted for  a 1MW rapid-fire laser  to significantly reduce aiming time. We then recommended  the Merc Forgrip  for improved hipfire accuracy, perfect for those crazy situations where you don’t have time to aim.

Finally, since the ISO 45 has an incredible rate of fire,  45 Round Mags  give you extra ammo to burn through before you have to stop and reload.

It pairs well with  Ghost  , which is an Ultimate Perk that keeps you away from enemy UAVs. It’s hard to move around the map when the enemies know where you are, so it’s essential for playing aggressively.

As equipment, we recommend using an old-school combination  of a frag grenade  and  a flashbang grenade  . 

Players can unlock ISO 45  by completing Sector D19  of the Modern Warfare 2 Season 4 Battle Pass. Once all four lower rewards have been obtained, simply use another token to unlock the SMG faster.

The ISO 45 is a submachine gun with a high rate of fire and impressive stopping power. This is a traditional submachine gun that excels at close range but can still hold its own at medium range. It pairs well with an aggressive playstyle and is statistically one of the best guns in its class.
