The STB 556 gets unlocked when players reach account level 41. This weapon belongs to the Bruen Bullpup Platform and is one of the best Assault Rifles to use in MW2 and Warzone 2. Make sure to level up both the MX9 and HCR 56 to unlock all attachments in the Bruen Bullpup Platform. The STB 556 is overpowered at close range combat and does decent at mid range. However, you can equip a few attachments to build a class setup that's viable at mid and even long range. Players must have the Weapon Tuning feature unlocked for this gun, as the following class setup requires you to tune the attachments.

  • Receiver: STB 556 Receiver
  • Muzzle: Harbinger D20
    • Tune the Muzzle for maximum Aim Down Sight speed, and Aim Idle Stability
  • Barrel: 24.4" Bruen S-620
    • Tune the Barrel for maximum Aim Down Sight speed, and Recoil Steadiness
  • Optic: VLK 4.0 Optic
    • Tune the Optic for maximum Aim Down Sight speed, and Far eye position
  • Underbarrel: Bruen Tilt Grip
    • Tune the Underbarrel for maximum Aim Down Sight speed, and HIP Recoil Control
  • Rear Grip: Bruen Q900 Grip
    • Tune the Rear Grip for maximum Sprint to Fire speed, and Recoil Steadiness

Best equipment and Perks to use for STB 556 in Warzone 2

After equipping five different attachments, players need to choose Lethal and Tactical equipment, as well as select Perks for this Custom Loadout. Here are the best equipment and Perks to use for the STB 556 AR.

  • Lethal: Stim
  • Tactical: Drill Charge
  • Perks: Weapon Specialist

To acquire this Custom Loadout in Warzone 2, players can spend $5,000 at a Shop (Buy Station). Similarly, you can also infiltrate Strongholds and defeat AI combatants to get the loadout. There are also Black Sites and Loadout Drops, but these spots are highly contested by opponents. We recommend purchasing this loadout from the Shop, although be careful as enemies often camp these spots.
