In Warzone Season 4 Reloaded, Sniper Rifles have been buffed, and we have the best Swiss K31 loadout to make it a top weapon once more.

Raven clamped down on Sniper Rifles in Warzone Pacific Season 3 bringing to an end the tyranny of the Kar98K and Swiss K31. However, the Season 4 Reloaded buffs and nerfs have changed the meta again, making the Swiss more viable than it has been previously.

The rapid Sniper Rifle is no longer as dangerous as it once was thanks to nerfs, but players still tend to favor it for its speed and precision capabilities. In order to truly get the most out of this deadly rifle, you’ll want to pick the right attachments.

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 the game, 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 isn’t what it was in Warzone Pacific, but it can still be deadly.

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

Our Swiss K31 class utilizes the EOD and Amped Perks. EOD greatly reduces the damage from non-killstreak explosives and fire, whilst 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 or even the classic MAC-10.

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.
