Msg Heavy Weapon Unit 18 Raging Booster Model Kit Acc

From Kotobukiya. This super-large booster unit is just what your Frame Arms kits need for extra power! Each unit can be attached with a 3mm diameter connection, and can also be used as a built-in type of leg unit (exchange it with the Frame Arm's knees; the vectorized nozzle will expand to form an ankle unit).
