Finally got this thing working again...
Modify Torus mechbox, Guarder M150 FTK, Madbull Ultimate Hopup and Prometheus precision barrel. Torus is really an awesome mechbox and the new version has even been painted white
First, I sprayed it with black paint (so that it wouldnt shine so much). Then I ripped stripes of regular masking tape and sprayed the whole thing with OD paint. Simple . Just remember to rip off the pieces, so that you get a rough edge.
