COD MW3: The BEST MTZ-556 Loadout And Class Setup

After 120+ hours in MW3, here is my preferred MTZ-556 loadout.

Among all the weapons in MW3, the Assault Rifle category is the most used one, and if I mention some powerful ARs with exceptional capabilities, then MTZ-556 has to be on the list. So, if you want to continue the action in the world of Modern Warfare, make sure to have the optimal MTZ-556 loadout to dominate your opponents on the brand-new maps.

Key Takeaways
  • The MTZ-556 is a great early-game Assault Rifle in COD MW3 that offers reliable stats in terms of damage, firing rate, and stability.
  • To optimize the weapon for close-range combats, players can use HMRES Mod Suppressor, Bruen Heavy Support Grip, RB Crotalus Assault Stock, and 5.56 Nato High Grain ammunition. 
  • The benefit of using these attachments is that players will be able to take close-range fights in the most effective and dominating way.
  • The loadout and class setup favors the close-range combats, making the weapon an absolute beast in Team Deathmatches and War Modes.
  • The drawback of using this loadout in COD MW3 is that you will have to compromise on long-range engagements, as the damage is not the most effective in distant fights.

Best Attachments For MTZ

If I have to choose a primary weapon that will help me counter enemy squads and get to victory, I will say MTZ-556 is quite a reliable option, especially in early levels of the ranking when there are not many options available. The weapon offers a decent firing rate with reliable damage output.

With MTZ-556, You can use the following attachment:

  • Muzzle:  HMRES Mod Suppressor 
  • Underbarrel: Bruen Heavy Support Grip
  • Stock: RB Crotalus Assault Stock 
  • Magazine: 50-Round Drum
  • Ammunition: 5.56 Nato High Grain Ammunition
  • ADS Recoil Control
  • Hip Fire Accuracy
  • High damage bullets
  • Increased Muzzle Velocity
  • ADS Steadines
  • Aim Down Sight Speed
  • Limited effective range

For the muzzle, I would recommend using the HMRES Mod Suppressor to make it a stealthy beast. The muzzle will suppress the burst sound of the weapon and make it difficult for the opponents to track where the bullets are coming from. For stability, you can use the Bruen Heavy Support Grip, as it will improve the gun kick control and keep the weapon stable while firing long sprays.

To complement the loadout, I use the RB Crotalus Assault Stock in MW3. It significantly enhances the weapon’s recoil control and helps me to perform long sprays, especially when using extended mag. Finally, if you love to wipe out squads, then you must use the 50-round Drum with  5.56 Nato High Grain Ammunition. 

Using the Optic type is a subjective matter and depends on the player which type of sight suits them the most. If you’re looking for an all-rounder option, I would suggest using the Slate Reflector, as it will act as your friend in close as well as mid-range combats. Other than that, the iron sight of the MTZ is reliable enough to be used without a scope in indoor fights.

Once you equip your weapons with the most optimal attachments, you can complete the loadout by choosing the right perks and secondary equipment. To make the best MW3 MTZ-556 loadout, you can select the following gear.

Secondary Weapon

While you will be carrying out most of your engagements with the MTZ, there might be some times when a secondary comes in handy. For that reason, your backup must always be locked and loaded.

For a reliable secondary option, I recommend carrying the classic Renetti handgun. If you’re encountering multiple enemies and you run out of bullets, you can quickly swap to Renetti and continue the action of annihilating the enemies through its burst shots.

Perks And Equipment

Along with primary and secondary weapon options, there are some other perks and gear that assist you in combats.

Here is the most optimal gear that complements the MTZ Loadout:

  • Vest: Infantry Vest
  • Gloves: Quick Grip Gloves: 
  • Boots: Lightweight Boots
  • Gear: EOD Padding 

The Infantry Vest is a great go-to option as it increases the Tac sprint duration and reduces the refresh time. For fast switching, use the Quick-Grip Gloves, as they significantly improve your A weapon swap speed. For footgear, you can go with Lightweight Boots as they work on your movement speed and assist you while swimming

You can use the EOD Padding in the gear slot, as it considerably reduces the damage taken from non-killstreak explosives and fire. Since most of the perks and equipment will be locked at the early game stages, I have recommended the equipment and perks accordingly.

For Equipment, I would recommend the following options: 

  • Field Upgrade: Munition Box
  • Lethal: Frag Grenade
  • Tactical: Stun Grenade

In close-range engagements, you often run out of ammo due to non-stop combat actions. To counter the issue, I use the Munition Box to get an extra supply of ammo and keep the action going. Finally, to add a bit of spice to the overall action, I carry some grenades and use them when needed to catch enemies off-guard.

For lethal, you can go for the classical Frag Grenade, as nothing can beat the satisfaction of getting a neat kill with a timely cook grenade. For tactical, using the Stun Grenade is a decent choice as it helps to rush indoors and take out campers without giving them the opportunity to react. 

My Opinion On MTZ-556

After playing for more than 40 hours and testing out the MTZ in Warzone and Team Deathmatches, I will say that it is a pretty reliable assault rifle that is worth upgrading. If you decide to carry progression on the weapon, you will not regret it. The firearm offers decent recoil control and is easier to handle, which makes it a good option for beginners or those who struggle to cope with heavy recoils.

Other than that, if you want to truly master the weapon, then make sure to test it out yourself on the battlefield, and don’t hesitate to try out some alternative builds to see what suits you the best while customizing the loadout.
