Best M4A1 Setup Modern Warfare

This is the perfect setup for being aggressive on objectives and battling it out up close and personal while being highly mobile. Here are the attachments we’ll be using on this setup:

  • Barrel – FSS 12.4″ Predator
  • Optic – G.I. Mini Reflex
  • Rear Grip – Stippled Grip Tape
  • Underbarrel – Commando Foregrip

The Predator barrel gives some ADS speed while sacrificing some bullet velocity. We’ll use an optic in this build because it benefits this gun a bit, but it’s up to you if you want to use it or not. We will go with no stock to give us some increased ADS speed and movement speed.

The commando foregrip and stippled grip tape add extra recoil stabilization and aiming stability. Sprint to fire speed and movement speed will also be improved with this.


Here’s a good setup you can use for perks to be a good support player that can move around freely and help the team.

  • Quick Fix
  • Restock
  • Spotter

Field Upgrades

Semtex is a great choice for the lethal as always, and the flash grenade can be a good tactical addition to the build.

Kill Streaks

We recommend picking killstreaks based on your playstyle. Some good ones might be UAV, Cluster Strike, and Infantry Assault Vehicle to start out with.
