The best Black Ops 6 XM4 loadout and build

Our best Black Ops 6 XM4 build turns this popular Call of Duty assault rifle into a super-speedy shortcut to victory. Similar to the best BO6 SMGs, the XM4 can become a quick-firing monster by buffing its ADS speed and handling, all while maintaining the excellent range and high damage output typical for an AR weapon. It's reason enough to consider the XM4 one of the best guns in Call of Duty: Black Ops 6.

That said, you do need the right attachments, gear, and perks to turn your XM4 loadout into one of the best BO6 assault rifles. Furthermore, a good rifle is nothing without a good sidearm. Don’t worry, you don’t need to search for the best equipment yourself; in this guide, we’ll show you how to get the best XM4 build in Black Ops 6.

Recommended XM4 attachments: 

  • Muzzle: Compensator
  • Barrel: Long Barrel
  • Underbarrel: Vertical Foregrip
  • Rear Grip: Quickdraw Grip
  • Stock: Light Stock

This best XM4 build for Black Ops 6 focuses on boosting the firepower, accuracy and mobility of the base assault rifle. Using the Compensator adds vertical recoil control, while the Vertical Foregrip adds horizontal recoil control. The Long Barrel increases the damage range, and the Quickdraw Grip massively boosts the ADS speed.

The Light Stock further increases the mobility stats of the XM4, by adding a boost to Hipfire Movement Speed, Movement Speed as a whole, and when strafing. You’ll be able to pick enemies out at range, and quickly ADS to hit them with high damage, even if they’re further away.

  • Secondary: 9MM PM
  • Melee: Knife
  • Tactical Gear: Concussion
  • Lethal Gear: Semtex
  • Field Upgrade: Spring Mine
  • Perks: Dexterity, Assassin, Double Time
  • Speciality: Enforcer 
  • Wildcard: Tactical Expert / Gunfighter

To round out this best XM4 loadout, you’ll want to bring along the 9MM PM. It’s a surprisingly effective pistol, and with the right attachments you can improve its stability, and ramp up the ADS speed. 

Tactical Gear is a personal choice here, but given that the Concussion Grenade is already regularly appearing in Daily Challenges, you can earn extra XPO by using it. Semtex is the best way to go for a Lethal Gear option, as it can be used to stick enemies and guarantee a kill.

In terms of Perks, go with Dexterity, Assassin and Double Time. This will unlock the Enforcer Speciality, which grants a temporary buff to movement speed and health regen rate. The Spring Mine is a great way to rack up even more kills, just place it in hallways, and popular camping spots. Finally, go for the Tactical Expert Wildcard to give you extra Tactical grenades. Once you hit level 33, you can select the Gunfighter Wildcard if you wish, adding three extra attachment slots for your primary weapon. For the XM4, consider adding your optic of choice, the Fast Mag I to improve reload speed, and the Strelok Laser which tightens spread during the transition between hipfire and ADS.
