Best STB-556 Loadout In Warzone 2.0

I've played Warzone 2 for over 100 hours, and here is my loadout recommendation of STB-556.

The STB-556 is one of the best Assault Rifles in Call of Duty Warzone 2.0. It offers a well-balanced toolkit with several strengths that make it stand out from other ARs. Like most weapons, the STB-556 has several attachments and add-ons that push it to a whole new level. However, it can often be confusing to choose which setup is gonna suit you the most. So, let’s jump right in and look at the best STB-556 loadout in COD Warzone 2.0!

Warzone 2.0 encourages using weapons that are good for close-range and long-range engagements. The STB-556 is best in the mid to long-range territory, making it an ideal choice for an assault rifle loadout in Call of Duty Warzone 2.0. As such, we’re gonna be using attachments that make the STB-556 a beast for mid-range combat.

Best Attachments

Here are some of the best attachments that I recommend for STB-556:

  • Muzzle: Echoless 80.
  • Underbarrel: FTAC Ripper 56.
  • Laser: VLK LZR 7MW.
  • Magazine: 42 Round Mag.
  • Comb: FTAC C11 Riser.
  • Faster TTK.
  • Aiming Idle Stability.
  • Improved Hip Fire Accuracy.
  • Sprint to Fire Speed.


  • Decreased Sprinting Speed.
  • Slightly Reduced ADS.


Starting from the front of the STB-556, I suggest the Echoless-80 as the muzzle. This attachment brings numerous benefits to the weapon, such as buffing the damage range, recoil smoothness, and bullet velocity.

Moving on to the under barrel, the best attachment for this loadout is definitely the FTAC Ripper 56. This attachment hugely improves the overall accuracy and recoil control, as it helps aim idle stability, hip fire accuracy, and recoil stabilization.

For mobility, I prefer the FTAC C11 Riser as Comb. It helps me give extra ADS speed and sprint-to-fire speed. This makes the STB-556 a lot snappier and more agile, making it more effective in close-range combat. 

Best Perk Package

The STB-556 is already a great standalone weapon in Warzone 2.0. For this loadout, I’ll look at perks that work well for a battle royale mode. This includes helping with stealth and mobility, the top few key aspects to consider when you’re on a big map surrounded by enemies.

Apart from that, we’ll also be focusing on perks that add to the overall synergy between the equipment, weapons, and Warzone’s mechanics. This gives a complete class setup, a boost in power, and the best possible reliability, leading to a balanced STB-556 loadout COD Warzone 2.0.

  • Basic Perks: Overkill and Tracker.
  • Bonus Perk: Fast Hands.
  • Ultimate Perk: Ghost.

Best Secondary Weapon

With the help of Overkill, I can include a primary weapon as my second gun in the loadout. Since the STB-556 is an Assault rifle, you’ll need a secondary weapon that focuses purely on stopping power. This could be either long-range or close-range since the STB-556 already covers the mid-range territory.

Long-Range Option – Lockwood Mk2

If you’re looking for a weapon that controls long-range battles, the Lockwood Mk2 has your back. As one of the best Marksman rifles in COD Warzone 2.0, this gun balances damage, range, mobility, and accuracy.

Here’s a list of my recommended attachments:

  • Laser: Accu-Shot 5MW Laser.
  • Optic: Teplo-OP3.
  • Muzzle: FTAC Dreadnought.
  • Barrel: 25″ Buffalo Barrel.
  • Ammunition: .45 GVT Hollowpoint.

With these attachments, you can dominate the long-range battleground, one-shot or two-shotting your enemies from afar and finishing them off with the STB-556.

Close-Range Option – Lockwood 300

In a game like Warzone 2.0, where time to kill matters the most, you’ll need a weapon that finishes the enemy quickly while still being reliable enough to do it. As such, the best shotgun for that job is gonna be the Lockwood 300. This double-barrel shotgun is a close-range powerhouse that fires 2 bullets back to back, resulting in an immediate kill if shot accurately.

The Lockwood 300 is already a good weapon on its own, but to make it more reliable, you need to upgrade its speed and range. For that reason, we’re going to put on the following attachments:

  • Muzzle: XTEN V2.0 Choke.
  • Underbarrel: Matuzek 812 Barrel.
  • Laser: VLK LZR 7MW.
  • Buck: Buck-Pro.
  • Stock: Heist Stock Mod.

With these attachments, the Lockwood 300 becomes a tank for close-range encounters thanks to its upgraded damage range and speed. You can use this weapon in tightly packed corridors and rooms where you can clean house an entire squad on your own.

Best Tactical And Lethal Equipment

Finally, to make the optimal loadout for the STB-556 in COD Warzone 2.0, I have chosen the best equipment, Tactical and lethal, that’ll work well in Al Mazrah.  This equipment will give you a unique yet noticeable advantage over other players.

My equipment recommendation includes:

  • Tactical: Heartbeat Sensor.
  • Lethal: Thermite.
