How to unlock The Ettin AMR9 Aftermarket Part in MW3

Aftermarket Parts can completely change a gun in Modern Warfare 3 or Warzone, like “The Ettin” Conversion Kit for the AMR9.

The Ettin is an Aftermarket Part and Conversion Kit for the AMR9 SMG that “creates two stacked barrels that fire simultaneously” and “offers twice as much down-range damage at the cost of some accuracy.”

Here’s how to get one of the newest AMPs in MW3 during season one, The Ettin.

How to unlock The Ettin AMR9 Conversion Kit in MW3

Why can’t I equip The Ettin AMR9 in MW3?

On Jan. 10, shortly after the attachment went live, @CODUpdates tweeted that the team was “investigating an issue preventing the JAK Ettin Double Barrel Kit from being equipped after completing the Weekly Challenges requirement.”

In a new update on the next day, Jan. 11, the fix was in for the Ettin. It can now be equipped in the Gunsmith once the Aftermarket Part challenge is completed and unlocked.
