Best ISO 45 SMG Loadout in Warzone and Modern Warfare 3

Most MW2 weapons have been left in the dust and those that have a chance to shine are usually still overshadowed by the new generation of weapons. The ISO 45 is one of the very few that can keep up with the new guard. Thanks to its exceptional fire rate and high damage it keeps itself competitive.

• Barrel: 7″ EX Raptor V2
• Underbarrel: XTEN Phantom-5 Handstop
• Magazine: 45 Round Drum
• Optic: Slate Reflector
• Rear Grip: EXP Shear

To start our list, we use the 7″ EX Raptor V2 for every mobility stat increase to keep you on the move in Warzone. The XTEN Phantom-5 Handstop is a good increase to ADS speeds and a little helping hand towards recoil control. To finish off our mobility build we have the EXP Shear, not to be confused with the EXP Share, that helps us draw the SMG like Clint Eastwood.

Finally, the obligatory 45-Round Drum improvement for Warzone’s giant health and the Slate Reflect for a clean optic.

Best ISO 45 Perks

Here we will list our general perk package for Warzone, feel free to swap in other perks to your preference, but for those wanting a basic set that will do them good, then read on.

The best perks are as follows:

• Perk 1: Sleight of Hand
• Perk 2: Double Time
• Perk 3: Tempered
• Perk 4: High Alert

Since Warzone features double primary weapons, Sleight of Hand may just be the better option than swapping weapons, especially if you rock a sniper in your loadout. Reloading quicker cannot be underestimated in certain circumstances. Double Time is a must-pick in the Warzone environment, it can save your life, net you a win, and always has value.

We prefer Tempered in slot 3 as it gives us a faster plating time, utilizes more efficient plates, and frees up some backpack space for grenades, flashes, or other gadgets. As our last perk, we use High Alert as an option to give you much-needed information and save your life from unwanted sniper fire.

With MW3 being so heavily dependent on your moment to perform, we want to have the ISO 45 to be one of the fastest SMGs possible. Since it sports an incredible fire rate, we can overwhelm our opponents with walls of bullet fire and fast legs.

• Muzzle: Shadowstrike Suppressor
• Underbarrel: DR-6 Handstop
• Laser: VLK LZR 7MW
• Ammunition: .45 Auto High Grain
• Optic: Slate Reflector

The Shadowstrike Suppressor is an attachment with no downsides and the positive of keeping you off the minimap. For some mobility improvements, we use the DR-6 Handstop and the VLK LZR 7MW, increasing your ADS times and movement speed.

We need some extra oomph to our loadout so we use the .45 Auto High Grain so we can take down enemies quicker and more efficiently. Finally, the Slate Reflector is a good optic without clutter.

Best ISO 45 Perks

For our perks in MW3, we want to capitalize on our mobility and ability to run across maps with incredible speed.

The best perks are as follows:

• Vest: Infantry Vest
• Gloves: Quick Grip Gloves
• Boots: Climbing Boots
• Gear: Tac Mask

The Infantry Vest is a must-have for any high mobility class as it offers faster Tac Sprint and recharge speed for fast rotations through the maps. You’ll be drawing your secondary weapon at lightning speeds with the Quick Grip Gloves. Climbing Boots will have you swinging around vertical engagements like Spider-Man while negating the risk of any fall damage. Finally, the Tac Mask gives you some much-needed safety against Flashbang/Concussion equipment spam.
