What is the JAK Revenger Kit in MW3 and Warzone?

The JAK Revenger Kit is a conversion kit for the BP50, transforming the assault rifle into a submachine gun.

It grants a larger magazine ammo capacity, enhanced vertical recoil control, as well as faster fire rate, aim down sight speed, and movement speed.

These benefits come at the cost of bullet velocity, range, reload quickness, and horizontal recoil control.

With this aftermarket part, the BP50 turns into a formidable close range firearm that can rival the top SMGs of the current meta.

Here’s how to unlock the JAK Revenger Kit

To access this conversion kit, you need to tackle challenges in the fourth week of Modern Warfare 3 and Warzone Season 3.
