The MTZ-556 feels like the quintessential Assault Rifle. It’s easy to use, versatile, and downs opponents with a few well-placed shots. If you want to make it even better, let me show you the best MTZ-556 build in MW3, including attachments, loadout, and perks.

The MTZ-556 feels excellent right out of the box, but we can use Attachments to improve on its already strong foundations. Here’s the build I recommend:

  • Optic: MK. 3 Reflector
  • Muzzle: Shadowstrike Suppressor
  • Underbarrel: XTEN Phantom-5 Handstop
  • Barrel: MTZ Clinch Pro Barrel
  • Rear Grip: Bruen TR-24 Assault Grip

MK. 3 Reflector

It’s rare to find an Optic in Call of Duty that ticks as many boxes as the MK. 3 Reflector. This Attachment offers a wide field of view with a simple dot reticule. You could swap the Optic for one with magnification, as the MTZ-556 is stable enough for long-range engagements, but I think the MK. 3 Reflector is the right choice.

Shadowstrike Suppressor

If you’ve read any of my other build guides, you’ll see I often recommend the Shadowstrike Suppressors, but they really are fantastic. There are zero downsides to using this Muzzle attachment, and it keeps you off the radar while shooting.

This Suppressor does exactly what it says on the tin, and I recommend it if you want to engage opponents behind their lines.

XTEN Phantom-5 Handstop

There are plenty of decent under-barrel attachments in MW3, but the XTEN Phantom-5 Handstop is among the strongest. This Attachment gives us a significant boost to ADS Speed along with buffs to handling.

The DR-6 Handstop is another fantastic option, but as it’s locked behind Armory progression, the XTEN is an easy choice. This Handstop negatively affects our Hipfire performance, but at least we have a superb Optic to lean into.

MTZ Clinch Pro Barrel

The MTZ Clinch Pro Barrel grants a massive boost to our long-range game. Bullet Velocity is dramatically increased, along with Damage Range. We also get small bonuses to Stability.

As with the XTEN, we lose out on Hipfire performance, and these two attachments tie us into an ADS-centric playstyle. As Assault Rifles typically perform better beyond point-blank range, this isn’t an issue.

Bruen TR-24 Assault Grip

I often recommend extended magazines, but the default for the MTZ-556 is fine. As we have a free attachment to play with, I recommend the Bruen TR-24 Assault Grip for even more buffs to Recoil control.

Combined with our other attachments, this Rear Grip makes the MTZ-556 feel like a laser, and you can easily engage long-range targets.

Best secondary, tactical, lethal, and field equipment for MTZ-556 build

  • Secondary: Renetti or COR-45
  • Tactical: Stun Grenade x2
  • Field Upgrade: Munitions Box

The Renetti is a solid handgun and is well worth the slot if you can handle the burst fire. In my opinion, double stuns are the way to go for Tactical Grenades, and we can carry two with our Engineer Vest

There’s something to be said for Field Upgrades like the Comm Scrambler, but as I’m a mobile player, I rarely stick around long enough to reap the benefits. With this in mind, the Munitions Box is great for me as I can restock out on the field.

Best gloves, boots, gear, and vest for MTZ-556 build

  • Gloves: Quick-Grip Gloves
  • Boots: Covert Sneakers
  • Gear: Mission Control Comlink
  • Gear: Ghost T/V Camo
  • Vest: Engineer Vest

I love the ability to quickly switch to my secondary with the Quick-Grip Gloves, but most options are viable. The Covert Sneakers silence footsteps, which makes flanking so much easier, and they are among the strongest boots in MW3.

The Mission Control Comlink is great for keeping a steady stream of UAVs in the air. However, the Bone Conduction Headset is really good if you want extra help listening to footsteps, and the Ghost T/V Camo compliments it nicely.

I recommend the Engineer Vest as the ability to see enemy equipment is so valuable, especially in objective modes.
