Starting out the best M4 loadout MW3 has available in Season 2, we have the 419MM EXF Barrel, which makes the AR highly accurate in longer ranges. The ADS speed is affected a bit, but it’s mitigated by the other attachments.

The Harbinger D20 is the muzzle of choice as it improves the bullet velocity and firing aim stability. The ADS speed is affected once again, but doesn’t affect the overall performance.

The Phantom Grip is selected to mitigate the negative performance of the ADS, and it also improves the sprint-to-fire speed.

For the ammunition, we picked out the 5.56 armor-piercing rounds due to it being highly effective in all kinds of situations.

Finally, the loadout is complete with the Slimline Pro optic. You can use any dot sight in place of it if you prefer.

To finalize the class setup, here’s the recommended equipment:

  • Tactical: Stun Grenade
  • Lethal: Frag Grenade
  • Field Upgrade: Munitions Box
  • Vest: Infantry Vest
  • Gloves: Quick-Grip Gloves
  • Boots: Lightweight Boots
