Season 4 of Warzone's Pacific era is in full swing and sniper rifles in the battle royale are skyrocketing in popularity once again thanks to their deadly damage output and ability to eliminate an enemy with a single bullet.

Season 3 of the Black Ops Cold War era saw the addition of the Swiss K31 sniper rifle to the arsenal and it continues to feature in the loadouts of several players despite nerfs from Raven Software. Armed with impressive levels of mobility, the Swiss is one of few weapons featuring in the Season 4 meta following widespread sniper nerfs.

As the metagame continues to evolve with the Season 2.5 update on the horizon, the Swiss remains a popular choice among players looking to dominate long-range engagements.

With so many attachments to choose from, it can be tricky to determine which are the best to use on the Swiss. With that said, find the best Swiss K31 Warzone loadout along with the best attachments to use in this guide!

What Is The Best Swiss K31 Warzone Loadout?

Considering the Swiss K31 has become a permanent part of the meta, we've had plenty of time to master the sniper rifle. Check out the best attachments to use on the rifle in the table below.

GRU Suppressor
24.9" Combat Recon
SWAT 5mw Laser Sight
Bruiser Grip
Rear Grip
Serpent Wrap

As with most Warzone loadouts, this build focuses on improving damage output even further in addition to maintaining high levels of accuracy. The stats bars in the Gunsmith only tell so much but after using it on Caldera and Rebirth Island, it's one of the strongest long-range guns to use.

How to Unlock Swiss K31

There are two ways to unlock the Swiss K31. The first is to score 2 headshot kills with a sniper rifle in 15 different completed matches in either Warzone or Black Ops Cold War multiplayer.

The second requires players to kill 5 or more enemies with Critical Kills rapidly 100 times in Black Ops Cold War Zombies.

Best Swiss K31 Warzone Attachments

  • Muzzle: GRU Suppressor
  • Barrel: 24.9” Combat Recon
  • Laser: SWAT 5mw Laser Sight
  • Underbarrel: Bruiser Grip
  • Rear Grip: Serpent Wrap

This build manages to increase bullet velocity in addition to improving aim-down sight speed and ensuring accuracy is maintained when firing on a target hundreds of metres away.

Overall, the Swiss K31 excels in long-distance duels thanks to its immense damage and range capabilities that make it arguably the very best sniper to use in all of Warzone.

Best Swiss K31 Warzone Perks and Equipment

With the best combination of attachments ready to go, choosing a selection of Perks and Equipment to maximise your impact during a match is a key ingredient to succeed in the battle royale. Here are the best pieces of Equipment to use and the best Perks to select.


  • Semtex (Lethal)
  • Stun Grenade (Tactical)

As always, selecting utility is personal preference but on this occasion, I went for a Semtex and stun grenade combination.

The Semtex can be thrown quickly and can be stuck to an enemy, guaranteeing an elimination while the stun grenade slows down an opponent, making them easy pickings for the Swiss K31.


  • EOD (Perk 1)
  • Overkill (Perk 2)
  • Amped (Perk 3)

EOD provides an increase in explosive resistance which can often be the difference between staying alive or being sent to the Gulag if grenades are raining down onto your position during a gunfight.

Overkill gives you the chance to equip two primary weapons in the same loadout to improve versatility on the battlefield and Amped shortens weapon swap speed, making it very easy to switch between the Swiss K31 and the AMAX so you always have the right weapon out for the task at hand.

Is The Swiss K31 Good in Warzone?

Even without any attachments, the Swiss K31 sniper rifle is lethal in long-range duels. From the chest upwards, it's a guaranteed one-shot kill regardless of whether they have any armour equipped.

With some attachments equipped, the sniper moves into a league of its own thanks to its phenomenal mobility and lack of recoil.

If you're looking for something different to dominate the long-range fights, I recommend using the Swiss K31.
