How to get the JAK Signal Burst Holger 556 Aftermarket Part in MW3

The Holger 556 is already a favorite in Modern Warfare 3, but it may become even better thanks to a new Aftermarket Part during season one.

The JAK Signal Burst Conversion Kit for the Holger 556 fundamentally changes the weapon, turning it from full-auto to burst-fire, just like the powerful DG-56 or FR 5.56 weapons in its same archetype. But it must be unlocked via in-game challenges during season one as that is currently the only way to acquire it.

Here’s how to get the burst-fire Holger 556 attachment in MW3.
