This is part of my "I made it because I couldn't get it" series.

The Space Assault version isn't sold, so I had no choice. (Bandai, please! 2nd time asking!)
The base is an HGUC GM with an added head antenna, the front waist armor cut off, and the leg armor is beyond my skill level, so I gave up and just painted it to cover it up lol.
The shoulder cannons are from the single-barreled version of the HGUC Ball, cut off and mixed with some leftover bazooka.
The bazooka I had on hand was repurposed from an RG Gundam.
