A new MW3 and Warzone update dropped on January 23, and the headline changes are some significant buffs and nerfs to Aftermarket Parts.

Aftermarket Parts are unique attachments that convert guns into almost an entirely different weapon. Whether it transforms an SMG into a carbine or a revolver into a rifle, they totally shake up how guns work.

Unfortunately, this often means that they are difficult to balance within MW3 and Warzone. Although, 5 different Aftermarket Parts have gotten buffs or nerfs in the January 23 MW3 and Warzone patch, making them much better balanced than they were previously!

MW3 Fans Think the JAK Signal Burst Aftermarket Part Is Trash

Weapon Balancing Changes

Assault Rifles

  • Holger 556
    • JAK Signal Burst
      • Increased gun kick control benefit by 10%.
      • Increased recoil control benefit by 10%.
      • Decreased burst fire delay from 120ms to 90ms (-25%). 

Hopefully, players who were complaining about the JAK Signal Burst being “trash” will finally be happy with the gun now!

Battle Rifles

  • Sidewinder
    • JAK Thunder LMG Kit
      • Decreased bullets required to reach maximum rate of fire from 25 to 15 (-40%). 

As the JAK Thunder LMG Kit has an increasing fire rate as you continue to shoot, slowing this down will make the weapon more balanced.

Submachine Guns

  • AMR9
    • Increased rate of fire from 789rpm to 833rpm (+6%).
    • JAK Ettin Double Barrel Kit
      • Overhauled firing mechanism to simultaneously fire two bullets per shot.
      • Decreased aim down sight spread by 75%.
      • Decreased hipfire spread penalty by 50%.
      • Added locational damage multipliers (MW3 only).
        • Head: 1x
        • Neck: 0.9x
        • Upper-Torso: 0.9x
        • Lower-Torso: 0.9x
        • Upper-Arm: 0.9x
        • Lower-Arm: 0.8x
        • Hand: 0.8x
        • Upper-Leg: 0.8x
        • Lower-Leg: 0.8x
        • Foot: 0.8x
  • Rival-9
    • JAK Headhunter Carbine Conversion
      • Decreased burst fire delay from 80ms to 66ms (-18%).
      • Decreased sprint to fire penalty by 10%.
      • Decreased aim down sight time penalty by 7%.
      • Decreased hipfire spread penalty by 20%.
      • Changed damage multipliers and ranges (MW3 only)
        • Decreased maximum damage from 30 to 26 (-13%).
        • Decreased medium damage from 29 to 24 (-17%).
        • Decreased minimum damage from 25 to 22 (-12%).
        • Increased headshot damage multiplier from 1.3x to 2x (+54%).
        • Increased neck damage multiplier from 1.1x to 1.5x (+36%).
        • Increased upper-torso damage multiplier from 1.1x to 1.5x (+36%).

These changes fix the biggest issues with the Aftermarket Parts for the AMR9 and Rival-9.

The AMR9 JAK Ettin Double Barrel Kit will be much more accurate while the Rival-9 JAK Headhunter Carbine Conversion will be more accurate and mobile, alongside having a faster fire rate.

Marksman Rifles

  • DM56
    • JAK Signal Burst
      • Increased gun kick control benefit by 10%.
      • Increased recoil control benefit by 10%.
      • Decreased burst fire delay from 120ms to 90ms (-25%).

These changes will allow the DM56 with the JAK Signal Burst be more accurate at long range, while also being able to dish out damage faster.
