Sniping in Warzone has always been an integral part of Call of Duty’s battle royale, but not all of the game’s Sniper Rifles are worth your time. Here’s our breakdown of the best one-shot Sniper Rifles loadouts to use in Warzone, ranked from worst to best.

Back in the original Warzone, sniping was incredibly strong with powerhouses like the Kar98k and 3-Line Rifle running the show. Its sequel heavily nerfed snipers leaving them in a difficult spot and almost permanently out of Warzone’s meta.

The arrival of Urzikstan saw snipers gain popularity once again with there now being several one-shot options all benefitting from a range of playstyles. This has continued into Season 3 with yet another iconic Call of Duty sniper being added.

There are currently six different snipers capable of downing enemies in a single shot and this is our ranking of them based on which provides the best balance of damage range, ease of use, and handling.

Best Warzone One-Shot Sniper Rifles ranked

6. FJX Imperium

FJX Imperium previewed in Call of Duty: Warzone.

Best FJX Imperium Warzone Loadout

  • Muzzle: Sonic Suppressor L
  • Barrel: Fahrenheit 29″
  • Laser: VLK LZR 7MW
  • Ammunition: .408 Explosive
  • Bolt: FJX Blast

While the Intervention may be as stylish as it is iconic, this reimagination of the anti-materiel rifle isn’t all that great. It has a slightly lower bullet velocity than the other one-shot MW2 Sniper Rifle yet doesn’t excel elsewhere. It’s not a terrible choice but there’s little reason to use the FJX Imperium over every other gun on this list.

5. Victus XMR

Victus XMR previewed in Call of Duty: Warzone.

Best Victus XMR Warzone Loadout

  • Muzzle: Sonic Suppressor XL
  • Optic: SP-X 80 6.6X
  • Barrel: Mack 8 33.5 Super
  • Ammunition: .50 Cal Explosive
  • Rear Grip: Bruen Q900 Grip

The Victus XMR is a solid choice thanks to its above-average ADS speed and bullet velocity. It does struggle when used at long distances – beyond 150 meters – but is still a good option for sniping more aggressively at close to medium range.

4. MCPR-300

MCPR-300 previewed in Call of Duty: Warzone.

Best MCPR-300 Warzone Loadout

  • Barrel: 22″ OMX-456
  • Optic: KR Intlas LSJ-3
  • Barrel: 22″ OMX-456
  • Ammunition: .300 Mag Explosive
  • Magazine: 5 Round Mag

CoD’s latest rendition of the ever-popular Barrett is the best MW2 Sniper Rifle to use in Warzone. The MCPR-300 is effectively a better Victus XMR offering comparable bullet velocity but noticeably better ADS speed. It is the strong choice for aggressive sniping and can be lethal in the hands of a skilled player.


KATT AMR sniper rifle being previewed with no UI in Modern Warfare 3.

Best KATT-AMR Warzone Loadout

  • Muzzle: Sonic Suppressor XL
  • Barrel: Zang-34 Barrel
  • Bolt: Ephemeral Quickbolt
  • Stock: Tactical Stock Pad
  • Ammunition: .50 Cal Spire Point Rounds

Introduced with the MW3 integration, the KATT-AMR is the only Sniper Rifle capable of one-shot kills at any range. Furthermore, it can do so without having to use a special ammunition type giving it the best bullet velocity. However, newer seasons have introduced alternatives that beat it out thanks to their better handling and mobility.


MORS Sniper Rifle from MW3 and Warzone Season 3.

Best MORS Warzone Loadout

  • Barrel: Tonne Heavy Barrel
  • Stock: Superlite-90 Stock
  • Ammunition: HVP Anti-Materiel Slug
  • Rear Grip: OP-980 Grip
  • Bolt: Quick Bolt

It’s only natural that a literal railgun would be capable of one-shot downing enemies, and the MORS doesn’t disappoint. It doesn’t quite have the damage range of the KATT-AMR or the handling of the XRK Stalker, but this futuristic weapon provides a nice middle ground for those wanting the most well-rounded sniper rifle possible.

1. XRK Stalker

XRK Stalker previewed in Call of Duty: Modern Warfare 3.

Best XRK Stalker Warzone Loadout

  • Muzzle: Sonic Suppressor XL
  • Barrel: Fission 60 Barrel
  • Laser: Corio LAZ-44 V3
  • Ammunition: .50 Cal High Grain Rounds
  • Bolt: XRK Stalker Light Bolt

As of Season 2, the XRK Stalker can now one-shot down enemy players which has some incredible implications. This sniper is much faster than any of the others making it by far the best option for more aggressive sniper players. The only catch is that its maximum one-shot range is capped at around 70 meters. Even so, it is still the best one-shot sniper in Warzone.
