The JAK Lance is the second Aftermarket Part introduced in MW3 and Warzone Season 6, breathing new life into one of the game’s overlooked shotguns by making it relevant again.

When attached, this component adds a pressurized magazine to the MX Guardian, loaded with ballistic rivets. As the pressure builds while the weapon is idle, both accuracy and effective range increase significantly once it reaches maximum output.

This essentially converts the MW2 Shotgun into a rivet gun capable of one-shot kills in multiplayer and two-shot downs in Warzone. Remarkably, despite being a shotgun, this modified version of the MX Guardian can deal lethal damage beyond 50 meters, making it a formidable weapon.

If you're eager to try it out, here's how to unlock the JAK Lance AMP and get the conversion kit as quickly as possible.
