Looking for the best MTZ-556 loadout in Modern Warfare 3? Among the many Assault Rifles in Call Of Duty: Modern Warfare 3, the MTZ-556 is one of the strongest all-around choices, especially for new players. Reminiscent of the M13 in more recent Call Of Duty games but boasting superior fire rate and handling, the MTZ-556 is a reliable weapon that deserves a chance in everyone's arsenal.

In this guide, we'll break down our favourite MTZ-556 loadout, including the best attachments, secondary weapon, perks, and all the equipment that you need to make this easy-to-use gun even more effective.

Why use the MTZ-556 in MW3?

The MTZ-556 is one of the most dependable Assault Rifles and starting guns in the game, full stop. With decent attributes in every stat, from accuracy to damage, the weapon is especially reliable in close and mid-range scuffles. Players searching for a more efficient weapon for aiming across the map may want to look elsewhere, but everyone else is likely to be satisfied with the MTZ-556's ability to clear out objectives and blast through opponents with a steady stream of bullets.

Best MTZ-556 loadout in MW3

  • Muzzle: S-37C DL Breacher Device
  • Barrel: MTZ Clinch Pro Barrel
  • Stock: EXF Close Quarters Assault Stock
  • Magazine: 50 Round Drum
  • Optic: Slate Reflector

This loadout will give us boosts to damage, range, accuracy, and recoin control at the slight expense of mobility and handling. The MTZ-556 works best on small maps like Favela, Hardhat, or Skidrow, and this is a loadout attuned to standing steady in close-quarters combat and mowing down the opposition.

Muzzle: S-37C DL Breacher Device

We've chosen the S-37C DL Breacher Device for its great boost to melee damage. The smaller but still significant improvement to accuracy is also welcome, while any drops to ADS speed are minor. Since the MTZ-556 is particularly useful on Modern Warfare 3's more claustrophobic maps, you may also want to take a muzzle that makes you undetectable by rader, such as the HMRES Mod Supressor.

Barrel: MTZ Clinch Pro Barrel

The MTZ Clinch Pro Barrel ups bullet velocity and range while also improving aiming idle sway and firing aim stability. You'll sacrifice mobility with this barrel, but the boosts will be worth it.

Stock: EXF Close Quarters Assault Stock

The EXF Close Quarters Assault Stock helps to cancel out recoil with a minor decrease in ADS speed as the tradeoff. The MTZ Marauder STock is also a good option if you're willing to put up with a few more drops to mobility.

Magazine: 50 Round Drum

With its high fire rate, the MTZ-556 is a potent force to be reckoned with. You don't want to waste too much time reloading with such a fast-firing gun, so choose the 50 Round Drum magazine to stay in the game.

Optic: Slate Reflector

Your choice of optic is primarily a matter of personal preference, but the Slate Reflector's a sound go-to thanks to its straightforward, rectangular design. If you're already confident with your aiming skills, the default ironsights on the MTZ-556 may be enough for you. If this is the case, skip the optic altogether and select 5.56 NATO High Grain Rounds ammunition as your last attachment for even more velocity and range improvements.

Best MTZ-556 class setup: Secondary weapon


Even with a 50 Round Drum attached to your MTZ-556, there might be the odd occasion when you find yourself with an empty gun. When that's the case, rely on the Renetti for a nasty secondary weapon that'll tear up the competition.

Best MTZ-556 class setup: Perks and Equipment

Infantry Vest, Stalker Boots, Quick-Grip Gloves, Bone Conduction, Flash Grenade, Frag Grenade, Munitions Box.

We haven't emphasised movement as much with this loadout, but the Infantry Vest provides a tactical sprint buff while the Stalker Boots will offer additional strafe and ADS movement speed. You could also go for the Covert Sneakers if you want to take a stealthier approach and muffle your footsteps.

The Quick-Grip Gloves allow you to instantaneously switch to your secondary weapon, which pairs well with our Renetti. Meanwhile, the Bone Conduction headset helps you hear enemies trying to sneak up on you, though if you're playing against opponents that toss grenades everywhere, you should go with EOD Padding instead to reduce damage from explosives and fire.

Finally, we recommend a Flash Grenade for disorienting opponents, and for more lethal encounters or rushing objectives, the Frag Grenade or Semtex are both good, depending on your playstyle. You'll be burning through ammunition on a regular basis with this loadout, so be sure to include a Munitions Box in your field equipment loadout.

Best MTZ-556 alternatives in Modern Warfare 3


If you're in love with Assault Rifles but prefer one that's a little more viable at different ranges, you can't go wrong with the MCW. The MTZ-556's easier to use out-of-the-box, and its higher firing rate and above average mobility means it'll still serve as the superior firearm in close-quarters fights. Nevertheless, for greater flexibility on a wider variety of maps, the MCW currently reigns supreme.

That's a wrap on the MTZ-556. For a rundown of other Assault Rifles in MW3, see our guide to the best Assault Rifles in Modern Warfare 3. For an in-depth delve into the best all-around firearms, check out our guide to the best guns in Modern Warfare 3.
