MMOexp-COD BO7: The God-Tier XM4 Build Every Player Needs Before BO7 Drops
No matter your skill level or experience with Call of Duty: Black Ops 6, there's one loadout that's breaking the internet right now-the XM4 setup that's taking Chaos Nuke Town by storm. Whether you're a casual player just hopping on for fun or a seasoned agrinder prepping for Black Ops 7, this build is an absolute monster Call of Duty Black Ops 7 Bot Lobbies.
Let's break down this god-tier XM4 setup, how it works, and what makes it so deadly in the fast-paced chaos of BO6's most iconic map.
The Blueprint: Gumball Ballistics XM4
At the core of this setup is the Gumball Ballistics XM4 blueprint, one of the earliest bundles released in Black Ops 6. It's not just about looks-this blueprint gives you some of the cleanest iron sights in the game, meaning you can comfortably skip optics and focus entirely on attachments that enhance mobility, accuracy, and control.
With this setup, you won't just beam enemies across the map-you'll do it stylishly and with surgical precision.
XM4 Loadout Breakdown
Here's the full loadout that dropped 324 kills in Chaos Nuke Town:
Muzzle: Compensator
 Adds crucial vertical recoil control, keeping the XM4 laser-stable even during long bursts.
 Perfect for mid- to long-range fights where accuracy wins gunfights.
 Barrel: Reinforced Heavy
 The perfect balance between damage range and bullet velocity.
 This attachment ensures you can compete with LMGs and snipers at range without sacrificing close-quarters viability.
 If you play aggressively, this is your best friend.
Underbarrel: Ranger Foregrip
 Since the XM4 is already naturally stable, this adds both horizontal recoil control and a touch of sprint movement speed.
 The added mobility helps you weave through Nuke Town's tight corners and unpredictable spawns.
Magazine: 60 Round Mag (or 100 for Chaos Mode)
 60 rounds is the sweet spot-large enough to mow down multiple enemies without massive speed penalties.
 For Nuke Town's relentless spawn traps, you can swap to 100 rounds for pure chaos, though it'll slow you down.
Rear Grip: Ergonomic Grip
 Faster aim-down-sight (ADS) speed means you're always first to fire in close-range duels.
 Helps maintain aggression during constant engagement chains.
Stock: Infiltrator Stock
 Boosts aim-walking movement speed, letting you strafe faster and dodge return fire mid-fight.
 When combined with the laser, this adds unmatched fluidity to your aim and strafing movement.
Laser: Target Laser
 Enhances aim-walking steadiness while synergizing perfectly with the Infiltrator Stock.
 Optional: if you don't have the Gumball Ballistics blueprint, you can remove this and run your favorite optic (Microflex LED or Millstop Reflex work well).
Attachment Bonus: Recoil Springs
 Keeps your aim completely still, even in chaotic sustained firefights.
 Wild Card: Gunfighter
 Allows for more attachment slots, maximizing customization and letting you stack both precision and mobility bonuses.
Secondary, Perks, and Equipment Setup
A weapon is only as strong as the setup that supports it. Here's the full supporting class that made the XM4 unstoppable:
Secondary: Grav (Backup Weapon)
 Reliable, accurate, and perfect for clutch moments when you run dry mid-streak.
 Tactical: Stim Shot
 Quick healing to stay in fights longer, especially vital when spawn-trapping or chaining multi-kills.
 Lethal: Semtex or Frag Grenade
The player experimented with both, though Semtex is slightly favored for faster throws and predictable damage zones.
Perk 1: Scrambler
 Jams enemy radar, keeping your movement unpredictable while spawn-trapping or flanking.
Perk 2: Scavenger
 Essential for long streaks; keeps your XM4 stocked and your lethals/tacticals replenished.
Perk 3: Hunter's Instinct
 When you get a kill, your minimap pings nearby enemies-effectively a mini-UAV in perk form.
 Perfect for maintaining tempo when UAVs aren't active.
Perk 4: Slipstream
 Boosts overall movement speed and removes tactical sprint restrictions.
 With Black Ops 7 removing Tac Sprint entirely, this helps players acclimate to the new pacing ahead of launch.The Gameplay: 300 Kills of Controlled Chaos
So how does this build translate in real gameplay? Let's set the scene.
Chaos Nuke Town is pure mayhem-10v10, constant respawns, explosions everywhere, and spawn flips that happen in milliseconds. It's the kind of environment where weaker builds crumble, but the XM4 shines because of its versatility.
Throughout the match, the player methodically rotated between spawn points, locking down chokepoints while using harp (advanced UAV) and War Machine killstreaks to maintain pressure. With a mix of intelligent positioning and mechanical skill, he racked up over 324 eliminations, including multiple nukes and several overlapping streaks.
Even when the pace slowed, the build's consistency carried. Between the Ergonomic Grip and Infiltrator Stock, he could react quickly, peek aggressively, and escape near-death situations.
When combined with Stim Shot recovery and Hunter's Instinct's kill-tracking radar pings, he practically became an unkillable force of nature.
Killstreak Synergy and Flow
Here's how the killstreak rotation worked:
 UAV → Harp → War Machine → Dreadnaught (VTOL-like killstreak)
 Once the first UAV was online, Hunter's Instinct and Slipstream allowed seamless chaining of streaks. The War Machine was often used to clear objectives or reset enemy control before calling in the Dreadnaught, which rained destruction from above.
Even after dying mid-streak, Slipstream and Scavenger helped the momentum stay alive, and the map control quickly reset in his favor.
The Secret Sauce: Adaptation and Control
One reason this performance stood out wasn't just raw aim-it was adaptability. Mid-match, the player adjusted settings, swapped attachments, and even fine-tuned aim inversion issues on the fly. Despite frustration and chaos, the XM4 setup gave him complete control.
He also noted that patience is a hidden weapon in BO6. Many players rush Nuke Town aimlessly, but by combining scrambler stealth with predictive map control, he could anticipate spawns and pre-aim corners before enemies even appeared on radar.
And yes-a little luck helped too. Some fights were chaotic, with "Looney Tunes" deaths and Mickey Mouse moments, but overall, the XM4 stayed consistent, reliable, and deadly.
Final Verdict: The XM4 Meta Going Into Black Ops 7
With Black Ops 7 just a week away, players are already testing which BO6 setups will translate into early success next season. If Treyarch doesn't make major recoil or mobility adjustments, expect the XM4 to remain a top-tier all-around weapon for day-one lobbies.
Its simplicity, combined with attachments that cater to both precision and speed, make it the perfect gun for new players and veterans alike CoD Black Ops 7 Bot Lobbies.
And as for the 324-kill performance? That wasn't just luck-it was a showcase of what happens when build efficiency, mechanical skill, and map mastery align.
So next time you load into Chaos Nuke Town, grab this XM4 setup, enable Gunfighter, and channel your inner demon. Who knows-maybe you'll be the next one to break 300 kills.
