The Swiss K31 is one of the most popular Sniper Rifles in Warzone Season 3 and we’ve got the ultimate loadout to help you dominate your foes. 

If you’re looking to take Caldera by storm with a powerful Sniper, then look no further than the Swiss K31. This beastly bolt-action rifle offers great accuracy and a fast fire rate, allowing you to pile multiple headshots in the blink of an eye.

While it was already a contender shortly after its release, buffs in the eventual Season 4 Reloaded update pushed it even higher up the game’s rankings.

Now, in Season 3 Classified Arms, with a faster ADS Speed and improved overall accuracy, the Swiss K31 is a great pick for any Warzone Sniper fan.


In order to truly get the most out of this deadly rifle, you’ll want to pick the right attachments. Check below for a complete overview of our ultimate Swiss K31 loadout for Warzone Season 3.

The Swiss K31 build features all the standard attachments you’d expect.


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

As with any Sniper Rifle in Warzone, you need to be running the GRU Suppressor Muzzle. This attachment offers extra Bullet Velocity and damage range making it a must for those that wish to increase the Swiss K31’s kill potential at a distance. If that wasn’t enough, the added sound suppression will help keep you from being easily located when firing. 

The 24.9” Combat Recon barrel is also another vital attachment that should be prioritized. This barrel increases the Swiss K31’s bullet velocity, which enables hitting mid to long-range enemies much easier – an area that is incredibly important if you wish to claim more kills.

The Swiss K31 has quickly shot up the Warzone rankings in Pacific.

Next up is the SWAT 5mw Laser Sight and Serpent Wrap. Both these attachments drastically speed up the K31’s aim down sight time, making it even easier to quickly zap onto your target’s heads for those all-important cranium-crushing kills.  

Lastly, while most players opt to take the Bruiser Grip, we suggest you try the SAS Combat Stock for Aim Walking Movement Speed and ADS Firing Movement Speed. This allows you to peak enemy snipers and gain the advantage in gunfights as long as you land your first shot.

Make sure you pair the Swiss K31 with a meta SMG to cover all scenarios.

Perks and Equipment

  • Perk 1: E.O.D.
  • Perk 2: Overkill
  • Perk 3: Amped
  • Secondary: MP40
  • Lethal: Semtex
  • Tactical: Heartbeat Sensor

Just like our EM2 loadout in Pacific, our Swiss K31 class also utilizes EOD and Amped. EOD greatly reduces the damage from non-killstreak explosives and fire, while  Amped gives you faster weapon swap and equipment speeds. 


The Overkill perk enables the use of our MP40 loadout, which remains one of the best SMGs in Warzone Pacific. If that doesn’t fit your playstyle, consider running the Owen Gun, a weapon that has only recently burst into the meta.

While Overkill keeps you competitive across all engagement ranges, you’ll still want to pick up Ghost as soon as you can. 

Lastly, both the Semtex and Heartbeat Sensor help track down nearby enemies and give you the tools needed to flush out nearby campers. 

How to unlock the Swiss K31 in Warzone

This Swiss K31 loadout really packs a punch in Warzone Pacific.

In order to unlock the Swiss K31, you must complete the following challenge: Using Sniper Rifles, get 2 Headshot kills in 15 different completed matches.


Those that enjoy using the Kar98k Marksman Rifle will definitely want to add this Swiss sniper to their arsenal. Simply grind out either Warzone or Black Ops Cold War multiplayer matches to add it to your arsenal. 

Best Swiss K31 loadout Warzone tips

If you wish to take full of advantage of this weapon in Warzone, here are some tips you should know:

  • Running this weapon without a capable secondary weapon is dangerous. While it covers you at medium to long ranges, you will be vulnerable up-close. To complete this loadout, be sure to run either an SMG like the PPSh-41 or a strong close-ranged Assault Rifle.
  • The use of the perk Amped allows you to swap between weapons faster. In the event you need a different weapon in a sticky scenario, this will help you immensely.

Alternative to the Swiss K31 loadout

The Kar98k is great for players looking to mix deadly sniper shots with more mobility.

If you’re looking for an alternative to the Swiss K31, then consider using this Kar98k loadout. While it may not be classified as a Sniper, this iconic WWII Marksman Rifle really packs a punch. 

The Kar98k also has a similar playstyle as it has a high rate of fire, fast rechambering animation, and decent damage range. This makes it the perfect pick for those that enjoy the playstyle of the Swiss K31 but want a little more speed. 


Not only that, it’s currently the second most popular weapon in the game, so it’s definitely worthy of a loadout slot.

If you’d prefer to run an off-meta pick, consider checking out the LW3 Tundra, a powerful sniper that often goes under the radar.
