An essential weapon in Black Ops 6, we’ll explain how to optimize the XM4 with the best setup, accessories, perks, and more.
The XM4 assault rifle is an excellent choice for multiplayer in Call of Duty: Black Ops 6, readily available from the start. Perfect for close-quarters and medium-range combat, we’ll guide you through the best setup to make the most of the XM4.
Why Choose the XM4 in Call of Duty Black Ops 6?
Simply put, the XM4 is accessible from the onset and proves to be a fantastic weapon. Once you hit level 4, you’ll also unlock your loadout options, allowing for customization.
The XM4 is a solid choice for medium and long-range gameplay, especially for players who may not yet have other weapons at their disposal. We’ll present two builds that you can utilize effectively with this assault rifle.
What is the Best Setup for the XM4?
Tested and approved during the beta, the configuration hasn’t changed much, so here’s how to optimize it fully:
Accessible Configuration
- Muzzle: Compensator
- Barrel: Long Barrel
- Magazine: Extended Magazine I
- Stock: Lightweight Stock
- Attachment: Rapid Fire
META Configuration
The accessories require leveling your weapon to level 36.
- Sight: Merlin Mini
- Muzzle: Reinforced Compensator
- Barrel: Reinforced Barrel
- Underbarrel: Vertical Grip
- Attachment: Rapid Fire
The compensator enhances vertical recoil control, while the long barrel increases firepower, projectile speed, and damage range. It’s advisable to reach weapon level 44 to unlock an even better barrel.
The combat stock improves your weapon stability. An alternative you can unlock at weapon level 8 is the heavy stock. The advanced ergonomic grip enhances aiming speed, providing increased fire rate after jumping or sliding—ideal for players who favor movement-based playstyle.
The extended magazine increases your capacity to 45 rounds. While larger magazines are available, they may reduce your aiming speed. For the sight, choose an option you feel comfortable with; for instance, at weapon level 5, you can unlock the Kepler Microflex with a notably thin frame.
How to Optimize Your Loadout with the XM4?
Now that we’ve examined the ideal build, let’s focus on your loadout and the configurations you should consider:
- Accessories: the stimulant to enhance survivability, and the sticky bomb to deter foes
- Combat Upgrade: carry the Assault Pack to reload both stimulants and sticky bombs at any time. Alternatively, choose the Trophy System to maximize survival during point captures,
- Joker: Overkill allows you to carry an SMG as well
- Perks: aim for green perks up to unlocking the Strategist specialty if you prefer playing objectives. On the contrary, if you avoid capturing points, prioritize red perks until reaching the Executor specialty.
