In this guide entry we will explain how to unlock JAK Thumper-656 kit in MW3 and Warzone.
One of the weapons I would trade for anything in Warzone and never use in MW3 is the RGL-80. However, that was before they added a new grenade launcher conversion kit, which makes it fun to use three different types of ammo in this. The unlockable treasure for Week 4 challenges in MW3 and Warzone Season 4 is the JAK Thumper-656, which transforms the RGL-80 into a shotgun, sticky grenade launcher, or a hive of armor-piercing charges.

However, the best place to unlock the JAK Thumper-656 kit is in Warzone if you want to complete the Week 4 challenges as quickly as possible.

Don't hesitate to try out their different ammo types once you've unlocked the JAK Thumper kit in MW3 and Warzone. The bullets simply make the RGL-80 brittle. Only semtex grenades, which you can throw further with the RGL-80, are sticky bullets. Finally, but just as important, piercing rounds allow launchers to fire piercing magazines.
