November 21, 2023: Season 6 Reloaded is underway and we've adjusted the best Warzone STB 556 loadout and the best attachments to reflect the current meta.

Is the best Warzone STB 556 loadout any good with Season 6 Reloaded in full swing? That's one question on the minds of Warzone fans looking for the next best AR to use in Call of Duty's battle royale.

Armed with a strong rate of fire and controllable recoil pattern, this particular AR often flies under the radar of Warzone players and following the most recent weapon buffs and nerfs, it remains an excellent off-meta selection.

Before we share all the intel on the best STB 556 loadout, take a look at our guides showcasing the best ranked play loadouts and the best LMG.

What is the best Warzone STB 556 loadout?

  • Muzzle: Harbinger D20
  • Barrel: 508mm Rear Guard
  • Optic: Aim OP-V4
  • Ammunition: 5.56 High Velocity
  • Magazine: 42 Round Mag

This build provides a slight increase in damage range in addition to huge improvements in accuracy which comes in handy at longer distances.

Despite the meta continuing to evolve, this STB 556 build acts as a solid baseline if you're looking to master the rifle in Al Mazrah.

Best Warzone STB 556 attachments

The Warzone gunsmith contains a huge range of attachments giving players the perfect opportunity to select a combination that suits their style of play. Here's an unbeatable set of five to use on the rifle for the final weeks of Season 6:

  • Muzzle: Harbinger D20
  • Barrel: 508mm Rear Guard
  • Optic: Aim OP-V4
  • Ammunition: 5.56 High Velocity
  • Magazine: 42 Round Mag

Although the overall handling of the STB 556 takes a knock, this build is a surefire way to excel in mid-range engagements. The combination of 508mm Rear Guard barrel and 5.56 High Velocity ammunition guarantees high damage and minimal recoil in all scenarios.

Arguably the unsung hero of this build is the 42-Round Mag. Having enough bullets allows you to take down multiple enemies in quick succession without the need to take cover and reload.

How to unlock STB 556 in Warzone

Warzone utilises the same weapon unlock system as Modern Warfare 2. Some weapons require players to rank another weapon in order to unlock it but in the case of the STB 556, it's a straightforward process in Season 6.

All you need to do to get your hands on this particular AR is reach level 41. We recommend using a double weapon XP token before dropping in to unlock it as fast as possible.

Best Warzone STB 556 perks and equipment

Once the best STB 556 attachments are ready for battle, selecting the right perks and equipment is the next step in building the strongest loadout. Here are our recommendations:


  • Base: Double Time
  • Base: Bomb Squad
  • Bonus: Fast Hands
  • Ultimate: High Alert

Double Time doubles the length of Tactical Sprint while High Alert causes your vision to pulse when an enemy has managed to spot you. Having the extra awareness in Season 6 makes all the difference when navigating areas where there's minimal cover to keep your location hidden.


  • Frag Grenade (Lethal)
  • Stim (Tactical)

Is the STB 556 good in Warzone?

Once the damage drop-off in long-distance scenarios is addressed thanks to the above attachments, the STB 556 is a great weapon to use in close-range and mid-range combat. Although it doesn't feature in the meta, it's still a strong option to use over the course of Season 6.
