What Does the JAK Backsaw Kit Aftermarket Part in MW3 Do?

If you’re setting out to complete five of these challenges, you’ll probably want to know what the reward you’re going to get does. Well, the JAK Backsaw Kit Aftermarket Part allows you to “attach a high-capacity drum magazine to the Holger 556 alongside a double-barrel configuration allowing the weapon to fire two bullets at a time.” Shooting two bullets while your enemy only fires one sounds like a pretty sweet deal.

And that’s how to unlock the JAK Backsaw Kit Aftermarket Part in Modern Warfare 3 (MW3).
