The second aftermarket part in Season 6 of Call of Duty: Modern Warfare 3 is the JAK Lance Kit. This turns the MCX Guardian into a discount railgun, firing slow-moving bolts that will instantly kill an operator. It's a powerful weapon up close, but it's held back by its lack of projectile speed and limited attachment options.

Turn the KATT-AMR into a bolt-action rocket launcher by completing some of this week's challenges.

Today, we'll be looking at how to unlock this AMP and how to complete all 21 challenges added this week. This includes every set of challenges added in Multiplayer, Warzone, and MWZ. But first, let's talk about how the JAK Lance Kit works.

Week 2 Challenge Reward

Close

This week's unlock is the JAK Lance Kit for the MX Guardian, a full-auto shotgun from MW2. If you don't have this weapon unlocked already, you can earn it through the Armory Unlocks system.

While installed, the MX Guardian is converted into a railgun that shoots highly-pressurized bolts at targets. It's a one-hit kill anywhere on the body, but this comes at the cost of projectile speed and fire rate. You'll need to seriously lead your shots past 20 meters to hit anything with this gun. Each shot is preceded by a short delay as well.

Despite the in-game description, the gun's bolt pressure does not increase passively. This is most likely a bug.

    • Kills from the grave (such as dropping a cooked grenade) also count.
  • Use the Kastov LSW for the last challenge.
