The Peacekeeper MK1 returns to Black Ops 7 as an assault rifle/fast-rate carbine hybrid. Mobility is its edge, and for most situations close-to-mid range firefights, but otherwise, unmodified, it has excessive recoil and a short effective range. The perfect loadout seeks to achieve recoil pump-ability, bullet speed, mobility and sustenance for distances over 20-30m. In this article, we discuss what attachments bring the Peacekeeper MK1 nearer to the “meta tier”.
Characteristics & Limitations of Peacekeeper MK1
Before we choose attachments, it’s important to understand the native profile and restrictions:
- Fire rate & handling: One of the fastest ARs in BO7 beta.
- Recoil (vertical & horizontal): Heavy sway and kick, especially during long fire.
- Range & damage falloff: Poor over ~30-35 m unless supported with attachments.
- Mobility: Decent base mobility, but attachments can compromise speed if not chosen optimally.
- Ammo usage: Rapid fire rate = quick magazine exhaustion.
Thus, ideal attachments would (a) reduce vertical & horizontal recoil, (b) increase bullet velocity / effective range, (c) reserve as much mobility & ADS speed as possible, and (d) increase mag capacity or reduce reload disruptions.
Essential Loadout

- Sight: Lethal Tools ELO to achieve clear sight picture with less visual noise.
- Muzzle: Monolithic Suppressor or K&S Brake-2B to stay off radar and/or provide aggressive vertical recoil control.
- Barrel: 21″ DF-3 Merge Barrel, extending range and bullet speed to reduce damage fall-off.
- Underbarrel / Grip: EAM Steady-90 Grip (or Sentry Pro Handstop variant) to counteract both vertical and horizontal recoil and assist stability.
- Fire Mod / Buffer: Buffer Spring to refine recoil manners, particularly first-shot impulse and prolonged spray control.
Large Build
When opened using Gunfighter, you can also kit out with the following:
- Barrel extension: e.g. 23.5″ Longbow Barrel gives increased range at the expense of mobility.
- Magazine: Vulcan Reach Extension gives increased rounds per mag to offset fast firing.
- Stock: Swift-B Guard Stock assists in the recovery of lost mobility when the big attachments are attached.
- Grips: Rear grip or a second stability grip, e.g. Diveedge-7 Grip or Kinetic-Mk1, provide additional recoil reduction.
That will provide you with a powerful control with a superior effective range and sustainability within medium engagements.
Conclusion
In Black Ops 7, Peacekeeper MK1 offers a unique hybrid niche: AR killing power with near-SMG mobility. To do its best, the ideal build must balance recoil against effectiveness while staying mobile. As Gunfighter is unlocked, spread out to 8 attachments with added extended mags and stock attachments. With accurate aim, intelligent encounters, and optimal build, you will be ruling with the Peacekeeper MK1 in objective modes and core matches.
