The Mechanics of One-Shot Elimination in Warzone

Few feelings in Warzone match the satisfaction of downing a fully plated 300 HP enemy with a single precise headshot. However, not all sniper rifles can achieve this without specific ammunition attachments.

Verified One-Shot Sniper Configurations

KATT-AMR (Native One-Shot)

One-shot headshots at infinite range with standard ammunition. Heavy handling and slow ADS speed.

XRK Stalker (.50 Cal Explosive)

Faster handling than the KATT. Requires Explosive Rounds to guarantee 300 HP downs, reducing bullet velocity to ~620 m/s.

MORS (Railgun Charge)

Exceptional muzzle velocity with the Charge Barrel attachment. Penetrates thin cover for wallbang headshot downs.

Compensating for Explosive Round Velocity Drop

When running Explosive Rounds on the XRK Stalker, aim one head-height above the target at 100 meters. For extreme ranges beyond 150m, the KATT-AMR with High Grain rounds remains the undisputed king.
