Best Peacekeeper MK1 Class Setup in COD Black Ops 7: Fast TTK and Run-and-Gun Power
This guide breaks down the absolute best Peacekeeper MK1 class setup in BO7, explains why each attachment matters, make Call of Duty Black Ops 7 Bot Lobbies and walks through real gameplay performance to show how this rifle holds up in chaotic objective modes like Domination and Hardpoint.
If you enjoy fast-paced AR gameplay that rewards aggressive positioning and smart movement, the Peacekeeper might already be your new favorite weapon.
Why the Peacekeeper MK1 Is So Strong in BO7
What makes the Peacekeeper special isn't raw damage alone-it's the combination of fire rate, mobility, and consistency once properly tuned. In its base form, recoil can feel excessive, especially during longer engagements. But once stabilized, the Peacekeeper becomes a run-and-gun AR that competes with SMGs up close while still outgunning many rifles at medium range.
The goal of this build is to:
Maximize damage range for faster ETK
Control horizontal and vertical recoil
Maintain strong ADS and movement speed
Support aggressive, objective-focused gameplay
With this setup, the Peacekeeper thrives when you're constantly rotating, challenging lanes, and pressuring spawns.
Best Peacekeeper MK1 Attachments (8-Attachment Gunfighter Setup)
Because this build uses more than five attachments, Gunfighter is mandatory. The extra slots are what truly push the Peacekeeper into overpowered territory.
Optic: Lethal Tools ELO
While the Peacekeeper's iron sights are serviceable, the weapon's recoil pattern makes a clean optic far more reliable. The Lethal Tools ELO keeps sight picture clear across all engagement ranges, making it easier to stay on target during sustained fire.
This optic shines in:
Close-range snap fights
Medium-range lane control
Longer-range burst engagements
If consistency matters to you, this optic is a no-brainer.
Muzzle: K&S Stalker 57X or K&S Compensator
This is where player preference comes into play.
K&S Stalker 57X: Keeps you off the radar while firing, making it ideal for spawn pressure and streak building. If you can manage the recoil, this is the best option for aggressive players.
K&S Compensator: If recoil feels overwhelming, this option provides additional vertical recoil control, making the Peacekeeper easier to use at medium and longer ranges.
For true run-and-gun play, the Stalker is recommended-but the compensator is a great fallback.
Barrel: 23.5" Long Bow Barrel
This barrel is essential. The 23.5" Long Bow dramatically improves damage range, allowing the Peacekeeper to secure faster and more consistent kills.
With this barrel equipped, the rifle:
Competes with MXR builds
Outguns AK27 users at medium range
Feels far more lethal in lane fights
If you want the Peacekeeper's TTK to shine, this attachment is non-negotiable.
Underbarrel: Sentry Pro Hand Stop
The Sentry Pro Hand Stop tightens the Peacekeeper's recoil profile while also improving:
Horizontal recoil control
Aim sway delay
Aim walking steadiness
This attachment is what makes the rifle manageable in sustained gunfights. Without it, the Peacekeeper can feel unpredictable-especially when tracking moving targets.
Magazine: Barrage Extended Mag (50) or Vulcan Reach Extension (40)
The Peacekeeper's fire rate burns through ammo quickly, making extended mags incredibly valuable.
Barrage Extended Mag (50): Best for aggressive players who take multiple fights without reloading.
Vulcan Reach Extension (40): A lighter alternative if you prefer slightly better handling.
Both options are viable, but the 50-round mag shines in objective modes where enemies push in waves.
Rear Grip: Dive Edge 7 Grip
Running an extended mag comes with handling penalties, and the Dive Edge 7 Grip exists to counteract them.
This grip boosts:
ADS speed
Slide-to-fire speed
Dive-to-fire speed
Jumping ADS speed
For a run-and-gun AR, this grip is absolutely critical. It keeps the Peacekeeper feeling fast and responsive, even with heavier attachments equipped.
Stock: EAM Blitz Fire Stock
The EAM Blitz Fire Stock enhances:
Aim walking movement speed
Flinch resistance
This helps you win close and medium-range fights by strafing more effectively and staying accurate under fire. It also reinforces the Peacekeeper's aggressive identity.Fire Mods: Buffer Springs
Finally, Buffer Springs add extra horizontal and vertical recoil control, smoothing out the weapon's firing pattern even further.
This attachment is especially useful when bursting targets at range or fighting multiple enemies without resetting recoil.
How the Peacekeeper Plays In-Game
Once fully built, the Peacekeeper MK1 feels deadly but honest. It rewards smart positioning and controlled aggression rather than mindless spraying.
Key strengths include:
Fast sprint-to-fire and ADS speed
Strong aim walking mobility
Excellent close-to-medium range lethality
Reliable burst potential at longer distances
You will need to pull down slightly on the right stick during extended engagements, and burst firing is recommended beyond medium range. This isn't a laser-but it doesn't need to be.

Real Gameplay Performance: Chaos, Comebacks, and Streaks
Live gameplay showcased exactly why this build works. Even in messy Domination and Hardpoint matches filled with EMP spam, dogs, UAV clutter, and spawn flips, the Peacekeeper consistently delivered.
Highlights included:
Multi-kill lane holds
High-pressure objective defenses
Legion deployments flipping losing games
Near-nuke performances
There were plenty of classic BO7 moments-teammates losing spawns, enemies chaining streaks, and sudden triple caps-but the Peacekeeper remained reliable throughout.
On maps like Raid and Nuketown, the rifle excelled at controlling key routes while still allowing fast rotations. In several matches, Legion alone completely shifted momentum, proving how valuable score-focused builds can be.
Should the Peacekeeper Be Buffed?
The question many players are asking is whether the Peacekeeper deserves a recoil reduction. If that happens, it could easily become the best gun in Black Ops 7.
Right now, its recoil is the only real balancing factor. The fire rate, ETK, and mobility are already top-tier. Any additional recoil tuning would push it into dominant territory.
Final Verdict: Is the Peacekeeper MK1 Worth Using?
Without question.
With the right build, the Peacekeeper MK1 is one of the most rewarding assault rifles in COD BO7. It hits hard, plays fast, more CoD BO7 Bot Lobbies and thrives in aggressive, objective-heavy matches.
