ISO 45

Best Modern Warfare 3 ISO 45 attachments

In Modern Warfare 3, you can fully customise your selection of guns with attachments to alter the way they can be played, as well as change their stats, thanks to the gunsmith. With the optimal attachments, the ISO 45 can be changed to fit a variety of different play styles. Here's the best set of attachments to equip:

• Muzzle: Monolithic Suppressor S
• Barrel: 9" PTX Trainer
• Stock: Torrent Span-9
• Underbarrel: FTAC MSP-98 Handstop
• Rear Grip: EXP Shear

To prevent any kind of damage drop-off, the 9" PTX Trainer barrel is the way to go. The extra performance at longer distances drastically improves versatility.

For maximum recoil control, the trio of Monolithic Suppressor S, Torrent Span-9, and FTAC MSP-98 Handstop allow you to keep your crosshairs focused firmly on the intended target. The ISO 45 features a lethal rate of fire, so you may need a small amount of manual control to keep shooting straight.

Lastly is the EXP Shear rear grip which reduces sprint-to-fire and aim-down sight speeds enough to ensure you can react to any threat you may come across throughout a match.
