How to get the JAK Headhunter Carbine in MW3

Call of Duty: Modern Warfare 3’s weapons change drastically with a new feature called Aftermarket Parts, and one of the most unique is the JAK Headhunter Carbine.

AMPs like the JAK Headhunter Carbine can transform a weapon from one archetype to another entirely, effectively making it an all-new weapon. In this AMP’s case, it changes an SMG into an assault rifle, so fans of both can have fun with this gun no matter what they use on it.

If one of your challenges has you tasked with using the JAK Headhunter Carbine, we’ve got you covered with all of the info you need. Here’s how to get the JAK Headhunter Carbine in MW3.

What is JAK Headhunter Carbine in MW3?

The JAK Headhunter Carbine is a Conversion Kit for the Rival-9 SMG in CoD: MW3. This Aftermarket Part turns the Rival-9 into a burst assault rifle that fires shots in three-round bursts.

This attachment offers higher Bullet Velocity & Range, Gun Kick Control, Recoil Control, and Damage, but lessens the Aim Down Sight Speed, Hipfire and Tac Stance Spread, Sprint to Fire Speed, and Movement Speed of the weapon.

The JAK Headhunter Carbine is not the best AMP in the game. The Conversion Kit doesn’t make the Rival-9 quite strong enough to perform as an AR, and the recoil is still pretty substantial without a number of attachments.
