M15 MOD 0 Loadout: Best Attachments, Class Setup & BO7 Build Guide

Best M15 MOD 0 Loadout in Black Ops 7 – Attachments & Class Setup

• The M15 MOD 0 is the first assault rifle you unlock in Call of Duty: Black Ops 7, but it plays far better than a typical starter weapon.
• With the right attachments, it becomes a laser-stable mid-range rifle that’s perfect for multiplayer and Mastery Camo progression.

Why the M15 MOD 0 Is So Strong

At a glance, the M15 MOD 0 looks like a familiar, “basic” AR, similar to an M4 setup you’ve seen a thousand times. But in Black Ops 7 it stands out because of its excellent baseline handling and very consistent time-to-kill over mid-range distances. That makes it a perfect weapon to invest in early, especially if you’re planning on grinding the long road to BO7 Mastery Camos.

Best M15 MOD 0 Loadout (Multiplayer)

Here’s a strong all-round M15 build focused on recoil control, mobility, and staying off the radar while still snapping onto targets quickly:

• Optic: Lethal Tools ELO
• Muzzle: VAS 5.56 Suppressor
• Barrel: 15" Mirage Light Barrel
• Magazine: Mayday Extended Mag
• Rear Grip: Contour Grip
• Stock: Wander-3V Stock
• Laser: 3mW Motion Strike Laser
• Fire Mods: Buffer Spring

This setup leans into what the M15 already does well and pushes it further. The Mirage Light Barrel, Contour Grip and Wander-3V Stock all stack to improve aim-down-sight speed, sprint-to-fire and strafe speed, making the rifle feel extremely snappy even while you’re jumping, sliding or shoulder-peeking corners.

The VAS 5.56 Suppressor keeps you off the mini-map without hurting ADS speed, while the 3mW Motion Strike Laser helps extend effective range and tighten recoil so you don’t need a compensator or heavier barrel. The Buffer Spring fire mod further trims both vertical and horizontal recoil, keeping the rifle steady even in long bursts. Finally, the Mayday Extended Mag gives you the extra bullets you need for multi-kills and aggressive pushes.

Gunfighter vs 5-Attachment Builds

This build uses eight attachments, so you’ll need to equip the Gunfighter Wildcard to run the full setup. If you prefer a five-attachment build or don’t have Gunfighter yet, you can drop a few options while keeping the core feel:

• First to remove: the Laser and Magazine if you want a more stripped-back rifle.
• Then choose between keeping the Optic or running irons and preserving the Suppressor.

Even with only five attachments, prioritising the barrel, stock, grip and fire mod still gives you a very strong, easy-to-control assault rifle.

Recommended M15 MOD 0 Class Setup

To support this aggressive, mobile AR build, pair the weapon with perks and equipment that let you keep momentum and pressure on the enemy team:

• Wildcard: Gunfighter
• Field Upgrade: Drone Pod (Quick Launcher)
• Tactical: Pinpoint Grenade (On-Board AI)
• Lethal: Molotov (Heavy Pour)
• Perk 1: Lightweight
• Perk 2: Fast Hands
• Perk 3: Dexterity

The perk trio of Lightweight, Fast Hands and Dexterity is built around mobility and fluid handling: faster movement, quicker weapon swaps and better climbing and mantling help you constantly reposition. Your equipment loadout supports lane pushing and area control: Drone Pod pressures enemies automatically, Pinpoint Grenades help reveal targets through walls, and Molotovs control chokepoints or flush enemies out of cover.

Tips for Leveling the M15 & Grinding Camos

The M15 MOD 0 has a long upgrade path, with many levels to grind through if you plan to chase high-end camos. A few simple habits make the process less painful:

• Play objective modes with lots of engagements, such as Hardpoint or Domination, to maximise kill opportunities.
• Focus on one or two attachment setups rather than constantly swapping – this keeps your muscle memory consistent.
• Track camo challenges as you go so you can combine requirements (headshots, longshots, kills while moving, etc.).

Once you’ve mastered this build, the M15 becomes one of the most reliable ARs in Black Ops 7, ideal for both casual lobbies and more competitive play. It’s a perfect starter weapon to build around while you learn the maps, experiment with class setups and work towards the long Mastery Camo grind.
