Waist and upper legs : VVV cobra viper
Rest of the body : Barrell Roll
My BR's legs used to flip ridiculously right and left, perhaps because of their thin shape, so I tried another waist and legs, and everything's ok now. I had to repaint the entire figure then, and the fun part was to paint all the details and pouches on BR's uniform. I wanted to give him a darker look, something closer to his brother Blackout.
