XM4 Best Attachments & Class Setups Black Ops Cold War

The XM4 is a fully automatic assault rifle in COD Blops Cold War. It is described as having reliable damage with an improved fire rate. It is a pretty decent weapon for a gun that comes unlocked at the start of the game. 

In this review, we go through the weapons statistics such as damage, rate of fire, and recoil. We also suggest the best attachments to use based on the weapons stats. 

Finally, we provide the top three XM4 class setups to use. Each class is built for a specific reason. Check it out below.

Weapon background

The XM4 in Black Ops Cold War is similar to the famous and popular Commando in Black Ops 1. The community is just calling it the Commando because it is more or less the same weapon. 


  • Damage: 30
  • Rate of Fire: 772 RPM
  • Recoil: Moderate

XM4 Cold War Best Attachments

The best attachments for the XM4 in Cold War are the:

  • Infiltrator Grip
  • 40 Round Mags
  • Speed Tape
  • 13.5” Reinforced Heavy Barrel
  • Serpent Grip

These attachments combined add overall speed to the weapon’s usability. The 40 Round Mags are essential on the XM4 because the weapon comes with less starting ammo. The base weapon gives you a total of 90 rounds.

Best Class Setups

Below are the best class setups you can use on the XM4. 

Class 1 – Max Speed

The first class is built for speed. This class maximizes the XM4’s ADS and sprint out times. Attach the following onto the weapon:

XM4 Gunsmith:

  • SOCOM Eliminator
  • 13.5” Reinforced Heavy Barrel
  • Infiltrator Grip
  • Serpent Grip
  • Raider Pad

Class Setup

The rest of the class works well when staying around the objective and good for those busy players that like to stay aggressive. Tas Mask will make sure you hold your ground while defending the objective. Ghost will keep you off enemy radar pings just make sure you stay on your toes.

  • Perk 2: Scavenger
  • Perk 3: Ghost
  • Lethal: Lethals
  • Tactical: Flashbangs

Class Setup

The remainder of this class keeps in mind a bit of everything. The most important parts are the perks. Flak Jacket to protect you from explosives.
