The JAK Cataclysm transforms the RPK from an LMG to a .50 Cal sniper rifle and has all of the characteristics of a meta weapon in Modern Warfare 3 multiplayer and Warzone.
Conversion kits have worked wonders on a few weapons that previously struggled to get any use. Thanks to the JAK Patriot conversion kit, the M16 went from one of MW3’s worst ARs into one of the title’s best thanks to full-auto fire capability.
Meanwhile, the JAK Revenger kit transformed the BP50 from an underused and disappointing AR into an SMG capable of competing with any top short-range meta weapon.
Sledgehammer Games also struck gold with the JAK Raven kit. Although the MCW is a solid AR, it shines even brighter as a fast-firing SMG. Similarly, the RPK has always been a good weapon, but the new JAK Cataclysm conversion kit elevates the LMG to another level.
How to unlock the JAK Cataclysm conversion kit
Unlock the JAK by completing five weekly challenges from Season 5, Week 2. These challenges can be completed across multiplayer, Warzone, and Zombies, or even a combination of the three.
