- "A pressurized magazine that fires three ballistic rivets, one per magazine rotation. Pressure builds while the weapon is idle until the maximum output is reached. At critical pressure, velocity and precision are vastly improved."
- — In-game description
The JAK Lance is a conversion kit for the MX Guardian shotgun featured in Call of Duty: Modern Warfare III as part of the Aftermarket Parts system. It was added as part of the Season Six update.
The JAK Lance converts the MX Guardian into a pseudo-marksman rifle, sacrificing magazine capacity, fire rate, velocity, and overall range for a bolt projectile, decreased hipfire and Tac Stance Spread, and aiming walk speed, each shot requires a brief build-up period before firing off a bolt.
