Head - Gnawgahyde (modified)
Lower arms - Steel brigade
Body - ROC Desert Ambush Duke
Bandoleer - custom

The funny thing about this custom is how I acquired the parts. I had given up on trying to trade for the Duke body on which I planned to base the figure. Then I completed a trade with Bucky for some random fodder. I had no idea what he was sending me and he had no idea I was planning an Ambush custom. When I received the fodder, the body of my Ambush was in it, already partially modified/painted in just the ways I wanted! Also, I sculpted a lot of hair on the Gnaw head to turn him into Ambush.
