How to unlock JAK Devastators in MW3 & Warzone

The JAK Devastators Aftermarket Part has arrived in Warzone and Modern Warfare 3, letting you dual-wield the classic SPAS-12 Shotgun.

These Aftermarket Parts are essentially new weapon attachments that can completely change how they behave. We’ve seen an underbarrel Chainsaw arrive, and the RPK turn into a .50 Cal sniper.

Once you’ve got the Devastators, you can become a “mobile artillery barrage” with a Reclaimer 18 in each hand, so here’s everything you know about how to unlock the JAK Devastators.

How to get JAK Devastators in Warzone & Modern Warfare 3

To unlock the JAK Devastators in MW3 and Warzone, complete five Week 8 challenges across multiplayer, Zombies, and Warzone.

It doesn’t matter which mode you play, just complete any five of these weekly challenges and you’ll unlock the JAK Devastators:

Multiplayer

• Get 20 Operator Akimbo Kills
• Get 10 Operator Headshot Kills using Pistols or SMGs
• Get 5 Kills against Operators who are blinded or stunned with SMGs
• Get 2 Operator Clean Kills in one life two times

• Get 100 Kills after reloading with Assault Rifles

The JAK Devastators let you equip two Reclaimer 18s at once, doubling the firepower. The devs said “Accuracy and recoil control are minimal, but destruction is maximized.” While they can one-shot players at point-blank range, the damage drop-off is severe so make sure you’re getting in close if you plan to use them.

Week 8 marks the final week of Season 5 ahead of the Season 6 update, also bringing the Chainbreaker camo reward if you have completed five challenges in all eight weeks of the season.

Season 6 will be the final seasonal update of MW3 and Warzone before Black Ops 6 arrives on October 25.
