⭐ Best Perks for the M15 MOD 0 Class

Perk 1: Ninja

Stay silent while sprinting and moving around the map. This is a must-have for flanking, breaking setups, and staying unpredictable in gunfights.

Perk 2: Fast Hands

Fast Hands keeps reloads and equipment swaps quick, which works perfectly with the 45-round magazine and aggressive playstyle.

Perk 3: Dexterity

Dexterity improves vaulting, mantling, and weapon swap speeds—letting you play faster, take routes quicker, and stay ready for close-range fights.

⭐ Wildcard: Gunfighter

Choosing Gunfighter unlocks extra attachments and lets you maximize the M15 MOD 0’s strengths.
This wildcard pushes the rifle into top-tier versatility by giving you improved recoil control, more mobility, and better all-around performance.

⭐ Best Equipment Setup

Field Upgrade: Trophy System

Running a Trophy System keeps you alive longer when holding hills, anchoring lanes, or defending objectives. It cancels out enemy grenades and tacticals—huge for objective players.

Tactical: Stun Grenade

Stuns are essential for clearing rooms, cutting off rotations, or forcing enemies out of power positions. Throw a stun, push with confidence.

Lethal: Frag Grenade

Frags remain one of the most reliable lethals in the game. Whether you're cooking it to force enemies from cover or throwing long-range nades to break setups, it adds consistent value every match.

⭐ How to Play This M15 MOD 0 Class

This class shines when used by aggressive slayers and objective players. Here’s how to get the most out of it:

• Use mobility to take early map control

• Strafe-shoot at mid-range—the angled grip reduces recoil while allowing fast movement

• Pre-aim lanes with the Lethal Tools S optic for crisp long-range shots

• Use Ninja to flank silently, especially when breaking Hardpoint hills or Search & Destroy sites

• Push with stuns, then cleanup with the M15’s fast-time-to-kill

• Drop the Trophy System on objectives to keep pressure off your team

With the combination of low recoil, great handling, and powerful perks, this M15 MOD 0 build excels in both casual and competitive environments.

If you want one of the best all-around AR setups in Call of Duty right now, this M15 MOD 0 class is a top-tier choice. Whether you're pub-stomping or competing in tournaments, this build gives you elite accuracy, mobility, and control.
