I had previously done this but with TF Lifeline legs. However, the paint didn't match 100% and it was kinda hard to fit him into the green HISS tank. I managed to get a pair of SDCC Grunt legs for cheap so I modded the holster and put it on my Steeler. Now the color matches and he fits the vehicle much better. The Grunt legs are not my favorite but at least the color matches.
