The JAK Widemouth Aftermarket Part is now available to unlock in MW3 and Warzone. This conversion kit is exclusively designed for the MORS sniper rifle, transforming it into a close-range shotgun. The barrel modification allows the sniper to shoot magnetic ball bearings that shatter upon firing, creating a barrage of small and lethal projectiles.

Equipping this Conversion Kit makes the weapon extremely powerful at close range, but its effectiveness diminishes significantly with distance.

To unlock this Aftermarket Part, you must complete a few Season 5 Week 1 challenges. This guide will outline the steps to unlock the JAK Widemouth Conversion Kit in MW3 and Warzone.
