Is the Peacekeeper Mk1 good in Warzone Season 4?

Yes. The Season 4 patch dropped both horizontal and vertical recoil by 8% and buffed its core attachments, pushing the Peacekeeper Mk1 firmly back into the meta. It's one of the best Sniper Support ARs in the game right now — SMG-fast handling with enough range to punish anyone who pushes you.

What is the best Peacekeeper Mk1 loadout for Warzone?

The Sniper Support build: FANG HoverPoint ELO optic, Redwell Shade-X Suppressor, 19.4" Stimulus Barrel, Vulcan Reach Extension mag, and the MFS Counterforce-C1 Stock. It's built for close-to-mid range with elite handling so you can swap to your sniper instantly.

Why use the Redwell Shade-X over the Monolithic Suppressor?

The Season 4 patch nerfed the Monolithic Suppressor's bullet-velocity bonus from 10% to 6%. The Redwell Shade-X now gives you the better all-round package on the Sniper Support build. Save the Monolithic for the dedicated long-range variant where raw velocity still wins.

Is the MFS Counterforce-C1 Stock worth it?

It's the build. The Counterforce-C1 is a Prestige Attachment and the single most important piece on the Peacekeeper Mk1 — it ties the recoil and handling together. Grind it out before you bother fine-tuning anything else.

What should I pair the Peacekeeper Mk1 with?

A sniper for the Sniper Support role — it's designed to bridge the gap while your sniper resets. If you'd rather run AR-plus-AR or an SMG secondary, the MXR-17 and Voyak KT-3 are the standout pairings in the current meta.

Best Peacekeeper Mk1 Loadout — Warzone Season 4 (Black Ops 7)

By TourneyTime · 22 June 2026

The page you bookmarked for the old Kilo 141 has had a glow-up. That gun — and the gunsmith it lived in — are long retired. What you actually want in June 2026 is the Peacekeeper Mk1, and after its Season 4 buff it’s one of the nastiest assault rifles in the game.

This is a full-auto AR that handles like an SMG in a suit. Lightning-fast ADS, brutal close-range pressure, and just enough reach to make pushing you a mistake. Here’s exactly how to build it and run it.

Quick Answer — Best Peacekeeper Mk1 Loadout

The meta Warzone build is the Sniper Support setup. Copy these five attachments and you’re done.

Slot	Attachment
Optic	FANG HoverPoint ELO
Muzzle	Redwell Shade-X Suppressor
Barrel	19.4” Stimulus Barrel
Magazine	Vulcan Reach Extension
Stock	MFS Counterforce-C1 Stock

TL;DR: elite handling, controllable recoil, full ammo for a fight, and the suppressor to keep you off the map. Pair it with a sniper and you cover every range a squad can throw at you.

Why This Build Works

The Peacekeeper Mk1’s whole identity is handling, so this loadout leans into that instead of fighting it.

MFS Counterforce-C1 Stock — the keystone. It’s a Prestige Attachment and it’s what turns a snappy-but-spicy AR into a laser. Everything else is built around it. Grind it first.
19.4” Stimulus Barrel — Season 4 made this a no-brainer. The horizontal-recoil benefit jumped from 10% to 18% and the velocity penalty was cut from 10% to 6%. Free recoil control with barely any downside.
Redwell Shade-X Suppressor — keeps you off the minimap and steadies the gun. The classic Monolithic Suppressor took a velocity nerf in Season 4 (10% to 6%), so the Shade-X is the correct call on this build now.
Vulcan Reach Extension — you need the rounds to finish a downed-then-revived squad. Running dry mid-fight on an aggressive AR is how you lose winnable gunfights.
FANG HoverPoint ELO — clean, low-clutter sight picture for fast target acquisition. Nothing fancy, exactly what a run-and-gun AR wants.

The result: an ease-of-use score that sits around 9/10 on the trackers, with a sub-650ms time-to-kill inside 10 metres. It melts up close and stays usable out to mid-range.

Long-Range Variant

Want to stretch the Peacekeeper out and contest more of the map? Swap to this Long Range build — slower to handle, but it holds rounds together at distance.

Slot	Attachment
Optic	FANG HoverPoint ELO
Muzzle	Monolithic Suppressor
Barrel	25” EAM Heavy Barrel
Magazine	Barrage Extended Mag
Stock	MFS Counterforce-C1 Stock

Here the Monolithic Suppressor earns its slot back — raw bullet velocity matters more than handling when you’re holding angles. The 25” EAM Heavy Barrel stretches your damage range at the cost of mobility, so treat this as a hold-and-pre-aim build rather than a rusher. It’s a Contender pick, not the default, but it’s strong if your squad needs you covering lanes.

BO7 Multiplayer Class

The Warzone build doesn’t translate one-to-one to 6v6. For Black Ops 7 multiplayer, this leaner setup plays better in tight maps:

Slot	Attachment
Optic	Lethal Tools ELO
Muzzle	K&S Compensator
Barrel	23.5” Longbow Barrel
Underbarrel	Lateral Precision Grip
Fire Mods	Buffer Spring

Perks: Flak Jacket or Lightweight (Perk 1), Tech Mask (Perk 2), Dexterity (Perk 3). Run Perk Greed as your Wildcard if you want all four.

Equipment: Semtex (Lethal), Stim Shot (Tactical), Drone Pod (Field Upgrade).

This leans into the gun’s mobility. Lightweight and Dexterity keep your sprint-out and jump/slide accuracy sharp so you can play it like a rusher’s AR. The Peacekeeper unlocks at Player Level 52 if you’re still grinding to it.

How To Play It

The Peacekeeper Mk1 rewards aggression — but smart aggression.

Lead with movement. This gun’s edge is its ADS and sprint-out. Slide into rooms, jump-peek corners, and use Tac Stance up close — it’s genuinely strong on this weapon.
Stay in your range band. It eats people inside 30m. Past 50m (the Season 4 medium-damage range was trimmed from 55m to 50m), let your sniper or a long-range secondary do the work.
Hold the suppressor discipline. With the Shade-X you’re invisible on the minimap — use that to rotate behind unaware squads instead of brawling head-on.
Don’t run dry. The Vulcan Reach Extension is there for a reason. Reload behind cover the second a fight breaks, not after.
