A new week means a new set of weekly challenges are live in MW3 and Warzone and this time, the JAK Signal Burst conversion kit is up for grabs. The JAK Signal Burst turns the Holger 556 into a deadly burst weapon, therefore many of the Week 5 challenges involve this particular assault rifle.
To earn the JAK Signal Burst, you must complete five challenges from Week 5. Whether you’re a fan of multiplayer, battle royale, or zombies, you can pick up the aftermarket part in your preferred mode.
