I built the EG version of the Full Armor Gundam Ground Type.

I chose Type B because of its diverse color scheme and to avoid the coloring being the same as the original Full Armor Gundam.

The twin beam rifle body was completely scratch-built from plastic materials. Magnets were attached to the rifle body and arm armor. The missile launcher was repurposed from the spray missile launcher of the old HGUC Guncannon. The rocket launcher was a mix-and-build using junk parts purchased from Yellow Submarine.

Making-of

Perhaps because it's 1/144 scale, the jettisoning...
