Best Attachments For The STB-556

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.

Muzzle: Echoless 80

Starting from the front of the STB-556, we’ll equip the Echoless-80 as our muzzle. This attachment brings numerous benefits to the weapon, such as its buffs to our damage range, recoil smoothness, and bullet velocity. With the enhancement to the damage range and recoil, this weapon becomes a lot more effective for mid-range and long-range engagements. Additionally, the time to kill is also improved with that bump in bullet velocity.

The Echoless 80 also gives you Sound Suppression, making it much harder to be detected on the minimap. Its only drawbacks are its slight decrease in performance to the ADS speed and stability, but they’re so minuscule that these drawbacks are hardly noticed in the game. Overall, the Echoless 80 is one of the best attachments for the STB-556 loadout in Warzone 2.0.

Underbarrel: FTAC Ripper 56

Moving on to the underbarrel, the best attachment for this loadout is definitely the FTAC Ripper 56. This attachment hugely improves our overall accuracy and recoil control, as it helps in our Aiming idle stability, Hip fire accuracy, and recoil stabilization. This is an ideal choice for players looking to make the STB-556 much more stable and easier to use. Another great thing about this attachment is that this is the first underbarrel you’ll unlock, so it’s pretty easy to get.

The FTAC Ripper 56 does slightly hinder our Walking and ADS speed, but since this attachment provides so much control and accuracy, these effects don’t cause too much of an impact.

Laser: VLK LZR 7MW

For our precision and accuracy, we’re only going to be sticking with only a laser, and the best choice for that category is the VLK LZR 7MW. This laser makes a ton of improvements to our ADS and mobility, such as bumping up the ADS speed and stability, along with the Sprint to Fire speed boost.

For the STB-556, its built-in scope is already very precise. Therefore, there’s no need to use up an attachment slot and get an Optic. Instead, we’ll take a laser that roughly offers the same benefits plus a few extra improvements. Its only drawback is the fact that it’s visible to enemies when you’re aiming. However, Al Mazrah’s bright environment means the effect of this drawback is minimal.

Magazine: 42 Round Mag

Assault Rifles often tend to eat up bullets in clutch situations. This is especially the case in Warzone, where you’re usually up against an entire squad and every bullet matters. Reloading in that situation is a death sentence, and for that reason, a 42 Round Mag will significantly improve the STB-556’s reliability.

This attachment makes the weapon a lot more consistent, and having those few extra bullets will help you down one or two more enemies. The only downside to this attachment is that it slightly slows down your movement. But that issue is canceled out by the VLK LZR, so it’s not a big deal.

Comb: FTAC C11 Riser

For our final attachment, we can go ahead and equip the FTAC C11 Riser as our Comb. This attachment is all about mobility, as it helps to 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. 

It’s important to bear in mind that the FTAC C11 Riser does worsen the stability of the weapon. However, this issue is compensated for by our underbarrel and laser, so it doesn’t make a big difference.

Best Perk Package For The STB-556

The STB-556 is already a great standalone weapon on its own in Warzone 2.0. For this loadout, we’ll specifically 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 our equipment, our weapons, and Warzone’s mechanics. This gives our complete class setup a boost in power and the best possible reliability leading to a balanced STB-556 loadout COD Warzone 2.0.


Showcasing the Overkill Perk

Overkill easily provides the best value out of any base perk in COD Warzone 2.0. This perk lets you equip a second primary weapon in your loadout, giving you extra versatility and stopping power. You could use either a long-range weapon for sniping or a close-range weapon to take advantage of sudden face-to-face encounters.

No matter how good a secondary weapon is, it can never match the consistency of a primary weapon, which is exactly why Overkill is so good. With this perk, you can add a lot more variety to your loadout without sacrificing anything.


Showcasing the Tracker Perk

Tracker is another great base perk that works well for Warzone 2.0, as it lets you see the footsteps of nearby enemies. This ability is especially helpful in houses and buildings where you can track down fleeing hostiles and campers. Other than that, you can also use it to camp near hotspots like Buy Stations, where enemy activity is more common, and be notified when someone is coming towards you.

This perk becomes even more useful in the endgame, where the map becomes tightly packed. You can see tracks of nearby enemies and avoid being ambushed. This also gives you the upper hand, where you know the enemy’s location and can figure out a way to handle them.

Fast Hands

Having two primary weapons, thanks to Overkill, means you’ll often be switching weapons according to the situation. That small interval leaves you vulnerable to enemy attack and can be dangerous in clutch situations. That’s why Fast Hands is the preferred choice for a Bonus perk since it makes your weapon-switching much quicker.

Fast Hands is even more effective in Warzone 2.0 since instead of 1v1s, you’ll be up against trios and quads. Other than that, when you’re taking fire or running around, you’ll need to switch your lighter weapon. However, switching to that weapon makes you slower for a few seconds, and that could mean the difference between life and the Gulag.


Showcasing the Ghost perk

The most common killstreak that players use in COD Warzone 2.0 is the UAV. This is because the UAV, along with being cheap, offers one of the best things a player could ask for – enemy locations. Revealing enemy locations means you can spot nearby targets and avoid being ambushed by another player or team. This is also the reason why players, including ourselves, equip the Heartbeat Sensor as our primary Tactical Equipment.

With the Ghost perk equipped, you can become undetectable to enemies with radar killstreaks and equipment such as a Heartbeat Sensor or UAV. This easily makes Ghost one of the best perks in the game and an ideal choice for Al Mazrah. Additionally, this perk also comes in handy during bounty contracts, where hostiles are specifically targeting you.

Best Secondary Weapon

With the help of Overkill, we can include a primary weapon as our second gun in the loadout. Since the STB-556 is an Assault rifle, we’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 offers a great balance between damage, range, mobility, and accuracy. Apart from that, the Lockwood offers nearly the same versatility as the STB-556 so that you can customize this weapon in a variety of ways, and it’ll be just as good.

For our loadout options, we’ll make the Lockwood Mk2 a powerful long-range Marksman rifle. Here’s a list of the 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’ll be able to 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’re gonna 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, we 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, we have to decide the best equipment, tactical and lethal, that’ll work well in Al Mazrah. Thankfully, we have a few standout choices that feel like they’re specifically designed for a battle royale. Therefore, it’ll give you a unique yet noticeable advantage over other players.

Heartbeat Sensor

Heartbeat Sensor reveals enemy locations within roughly a 50-meter radius in intervals. This is an excellent choice for a Tactical in Warzone 2.0 since stealth and info are key. With the sensor working as a mini-UAV, knowing nearby hostiles means you can catch them off-guard or position yourself in such a way that you have the advantage.

It is important to remember that this equipment will not reveal enemies that have the Ghost perk activated, so you’ll sometimes have to rely on footsteps to track down enemy players. Another major drawback of the Heartbeat Sensor in Warzone 2.0 is that it has a battery and will eventually run out. So use the sensor sparingly and try to reserve it for the end-game.


When it comes to a good balance between speed, damage, and range, no other equipment does it better than the Thermite. This lethal explodes upon impact, creating a burst of fire over a wide area of effect. As such, this piece of equipment favors throwing accuracy as a direct hit to an enemy tears through their shields and can often down them if they have none.

The Thermite is extremely quick to throw, quick to reach your opponent, and has a great range. Therefore, if you’re confident in your throwing skills and want to have effective lethal equipment, the Thermite is definitely for you.

Wrap Up

That wraps up our guide on the best STB-556 loadout in Call of Duty Warzone 2.0. It’s important to remember that the STB-556 is a great all-rounder weapon. So it can accommodate almost any play style. Other than that, the game also features weapon tuning so that you can customize each attachment to your liking. Thus, you should try different attachments alongside this weapon to see which one suits the most and gets you the easiest Warzone Victory!
