Premium Bandai announces the custom version of the HGAC 1/144 Gundam Heavyarms! It shares the same molds with the regular release version of its variant, with newly molded parts for its backpack – adding two more vernier units making it possible to maneuver in space. 

Its skirt armors are also given a new mold to make an accurate representation of the unit. The custom version will of course not be completed without its twin beam gatling installed on its left arm.
