The MSM-04 Acguy Heavy Firepower Type is a variation with an emphasis on firepower that swaps out both arms with large weapons units. The unit is supposed to be positioned in the center of a basic formation and function as the main force for the team.

The characteristics of both of the arms weapons units are a spray missile launcher in the right arm and a missile container on the left shoulder. Both can be disconnected after use and a simple manipulator is deployed following separation from the right shoulder joint. In addition, since the left arm needs to hold the container, it is replaced with its own arm unit. Also, it is equipped with a mission pack on its back with an iron blade as an auxiliary weapon. This is the same non-heat blade as the amphibious mobile suits iron nail, so its sharpness is exceptional but its not very durable.

Among the Daryl Team, the Heavy Firepower Type is piloted by Fisher Ness.

The diagram on the left illustrates the full loadout. The yellow highlight denotes the spray missile launcher, the red highlights the missile container, the purple highlights the arm unit and the green highlights the mission pack. The diagram on the right illustrates when the weapons units have been detached. The blue highlights the iron blade, the yellow highlights the simple manipulator that can be deployed.

The iron blades are the same non-heat blades used by the Z’Gok. Blade usage is not limited to just the Heavy Firepower type. While the blade is sharp, it breaks off easily. There is a mount latch on the back of the suit to store the blade.

The spray missile launcher has 12 tubes with a full loadout of 48 rounds. It is possible for them to be fired off individually. The launcher is locked when the suits are underwater.
