  • MW3 and Warzone Season 5 Week 3 Challenges
  • JAK Slash Underbarrel Review

Call of Duty: MW3 Season 5 Week 3 has started with a subtle change of direction in the reward type. This week we don’t get a new conversion kit that turns an LMG into a sniper rifle, but instead, we’ve got ourselves the JAK Slash aftermarket part underbarrel to use and unlock in MW3 and Warzone. This is a speed-focused attachment that also handles a bit of vertical recoil.

You can unlock the JAK Slash aftermarket part underbarrel by completing 5 out of 21 Week 3 challenges in MW3 and Warzone Season 5. As you can see, the route for unlocking this attachment in Warzone is quite hard and time-consuming, and for MWZ, it’s just going to take hours.

So the best way to unlock the JAK Slash is by check marking these 5 MW3 Multiplayer objectives:

  • Get 25 Hip Fire Kills
  • Get 20 Operator Kills With Silenced Weapons or Throwing Knives
  • Get 10 Hip Fire Operator Kills With Battle Rifles
  • Get 15 Operator Kills With Covert Sneakers Equipped or Dead Silence Active
  • Get 10 Kills With Lethal Underbarrel

You can complete all these challenges in a single match by running the loadout below:

The task is easy; just use this loadout and get some hip fire kills. Then switch over to your JAK Purifier underbarrel by pressing the left button on D-Pad. Burn 10 enemy targets, and that’s how you finish the MW3 and Warzone Season 5 Week 3 challenges to unlock the JAK Slash attachment.

With the JAK Slash underbarrel, we’re talking under 8% positive points for the movement speed. So while the challenges make it look like a treasure, JAK Slash ain’t nowhere near the best underbarrel attachments like the Paracord Grip and the DR-6 Handstop.
