Modern Warfare 3’s Multiplayer and Zombie modes require lethal weapons that oppress enemies with firepower and take them down at close, medium, and long ranges. Assault rifles are among the few weapons with impressive damage range and enough firepower to annihilate opponents in MW3. While there are numerous best assault rifles players can use to claim victory in matches, the M13B is one of the top-tier rifles.

The M13B has exceptional recoil control and a blistering fire rate to tear through zombies and enemies, making it the deadliest assault rifle in MW3. The weapon is highly accurate but has a low time-to-kill, which makes it vital to use the right loadout and class setup to enhance its limits. Here’s the best loadout for M13B in Modern Warfare 3.

The best Modern Warfare 3 M13B loadout is as follows:

  • Muzzle: Harbinger D20
  • Laser: VLK LZR 7MW
  • Barrel: 14" Bruen Echelon
  • Optic: Cronen Mini Pro
  • Magazine: 45 Round Mag

The Harbinger D20 keeps players off the enemy’s radar while boosting range, bullet velocity, and recoil control. The 14" Bruen Echelon Barrel adds to M13B’s versatility by increasing its damage range at close-quarters, mid-range, and long-range combat. So, players can use the rifle to take down opponents from afar or clear out a room in quick succession. The VLK LZR 7MW laser improves the gun’s speed, including sprint-to-fire and ADS speeds, ensuring players can move around quickly and easily.

Although the M13 B has an exceptional fire rate, adding a 45-round mag is necessary to increase ammo capacity. Modern Warfare 3’s enemies boast 150 health, so players need all the ammo they can get to defeat them. Lastly, the M13B has reasonable iron sights, but players can elevate it with the Cronen Mini Pro to improve accuracy and land more shots.

This M13B loadout is designed to maintain the gun’s exceptional recoil control while improving its speed and time-to-kill. It also ensures smooth handling and enhanced mobility.

To push M13B’s limits further, players should equip it with the right class setup. This includes an Infantry Vest to improve tac sprint and Commando Gloves to reload and sprint simultaneously. As for Boots, Covert Sneakers or Lightweight Boots are a great option to move around unnoticed and sneak up on enemies. Throw in a Battle Rage and a Frag Grenade to increase survival on the brutal Modern Warfare 3 battlefield.
