The JAK Lance is the second replacement part to arrive in MW3 and Warzone Season 6, which completely transforms one of the game’s forgotten shotguns, bringing it back to relevance.
When equipped, this accessory adds a pressurized magazine to the MX Guardian which contains ballistic rivets. Magazine pressure increases when the gun is at rest, with its accuracy and effective range greatly increased when maximum power is reached.
This turns the MW2 shotgun into a rivet gun capable of single-shotting enemies in multiplayer and downing them twice in Warzone. Despite being a shotgun, this version of the MX Guardian is capable of dealing lethal damage well beyond 50 yards, making it a truly powerful weapon.
Assuming you’re interested, here’s how to unlock the JAK Lance AMP and get your hands on this conversion kit as quickly as possible.

How good is the JAK Lance AMP?
The JAK lance is fantastic in MW3, but a mediocre option in Warzonewith a big flaw that makes it difficult to justify its use in Call of Duty battle royale.
In multiplayer, its ability to kill in one hit makes it a frightening weapon to face, especially in the hands of an experienced player. It is comparable to the Kar98k but with faster maneuverability and better hip-firing accuracy. Those who like to use the dominant sniper rifle will also have fun with this.
It’s a different story in Warzone, where this conversion kit is held up by its tiny three-round magazine. It takes two shots to take a player down and another shot to finish them off, meaning you have to use an entire magazine to ensure a single kill. Given its long cooldown, this is impractical, and so this AMP is unlikely to become meta without some substantial buffs.
