Warzone MX Guardian bug turns shotgun into near-instant delete button

A bugged MX Guardian build is turning Warzone’s close-range fights into instant deletions. With 12 Gauge Slugs and the JAK Lance Conversion Kit installed in the right order, the shotgun can reportedly drop fully plated enemies with a single shot, and it can also two-tap to the chest or finish a target with one headshot at point-blank range.

That attachment order matters, which is what makes this feel less like a normal balance quirk and more like a hidden exploit. The JAK Lance is not a mystery part either. Activision’s Season 6 notes from October 21, 2024, listed it as compatible with the MX Guardian shotgun and described it as a pressurized magazine that fires three ballistic rivets, with pressure building while the weapon sits idle. In other words, the platform already had a high-ceiling conversion path. The bug appears to push that ceiling far past anything intended.

The timing is awkward for Raven Software, which had already published Season 03 Reloaded patch notes on May 11, 2026, with bug fixes across Warzone, including an exploit that let players move under the map in Haven’s Hollow. Those notes also fixed an issue where the MX Guardian could incorrectly equip Dragon’s Breath rounds, showing the weapon has needed attention before. This new damage bug did not appear in that patch set, even as live fixes were already going out across the mode.

Warzone has seen this pattern before. When a shotgun or close-range weapon slips out of bounds, the entire pace of a lobby can change in a matter of hours. The DMR era and the Akimbo Snakeshot Pistols became infamous because they erased the normal risk-reward of pushing fights. The MX Guardian bug hits the same nerve, especially because the setup is already spreading through social media, which usually means the exploit is about to show up more often in regular matches.

If the build keeps circulating, the likely outcome is a nerf or even a temporary removal. For now, any player pushing a stairwell, hallway, or doorway has a new reason to dread a fully optimized MX Guardian, because in the wrong hands it is behaving less like a shotgun and more like a near-instant delete button.
