The Peacekeeper MK2 is one of the best assault rifles in Call of Duty: Mobile, and with the right attachments, it can be even better. Here is the best loadout we can devise for both standard multiplayer and battle royale game modes.
Assault rifles are some of the most powerful weapons in Call of Duty: Mobile. Accurate, fast-firing, and with plenty of firepower behind them, they are many players' go-to guns.
Some are better than others, and one such gun is the Peacekeeper MK2. First seen in Call of Duty: Black Ops III, the MK2 Peacekeeper is both highly accurate and mobile, with its accuracy, in particular, one of the best in the assault rifle class.
The gun is also highly and uniquely customizable, with a range of attachments available that aren't seen for any other gun, let alone an assault rifle. Picking the right attachments is vital to unlocking this gun's potential, but with such a dizzying array of attachments, it can be hard to decide which makes the gun perform best.
That's where this guide comes in, as we have devised the best Peacekeeper MK2 loadouts for both standard multiplayer and battle royale game modes.
Update: We made some minor changes to the loadout on September 17, 2025.
Best Peacekeeper MK2 Loadout
There are 53 potential attachments and perks for the Peacekeeper MK2, which you will need to unlock by leveling up the gun.
Once you have those attachments, you can kit out the gun in many ways, and it is viable in both standard multiplayer and battle royale game modes. It is especially capable in the battle royale, as the gun offers up insane range relative to other assault rifles, an attribute you can improve further with the correct attachments.
With that said, here are the best Peacekeeper MK2 loadouts we can devise for Season 8 (2025).
Best Peacekeeper MK2 Loadout For Standard Multiplayer
- Muzzle: Agency Suppressor
- Barrel: Taskforce Barrel
- Stock: Agile Stock
- Ammunition: Double Stack Mag
- Rear Grip: Firm Grip Tape
This Peacekeeper MK2 loadout is about improving the gun's range, fire rate, recoil control, and mobility.
Also, we have opted for the Agency Suppressor muzzle, which reduces vertical recoil by 10% and silences the gun with no adverse effects.
Best Peacekeeper MK2 Loadout For Battle Royale
Here are the best attachments for the Peacekeeper MK2 for the battle royale game mode:
- Barrel: Long-Range Barrel
- Optic: Tactical Scope
- Underbarrel: Field Agent Foregrip
- Ammunition: Large Extended Mag A
- Rear Grip: Firm Grip Tape
The Peacekeeper MK2 loadout gives the gun even greater range and accuracy than is already present in the base version. This comes at a small cost of mobility. Still, with the ability to engage opponents at extreme range, this loadout will keep opponents far enough away from you to mitigate the mobility cost.
To make this possible, one key attachment is the Long-Range Barrel.This barrel increases damage range by 100% and reduces horizontal recoil by 20% at a cost to ADS time and movement speed.
To counteract the increase in ADS time, the Firm Grip Tape is necessary, improving that metric and reducing hit flinch by 90%.
The Tactical Scope is a relatively lightweight magnified optic that will help you engage opponents at the long ranges this loadout is capable of.
We've opted for the Large Extended Mag A again, as this increases the magazine size, keeping you in the battle for longer.
