I recently finished the RAFMiniatures (A really matching name for a producer of terrorists). I liked the multi parts because you can build a lot f different poses with just one pack. I tried some different techniques to paint black, in my opinion the best and a simplest is to paint them in dark grey and simply wash them. So they look black not grey and flat. The photo is not optimal and I will upload a better later.
The miniatures bases are M8 zinc plated 2,5 cm in diameter. I recently bought a pack of a hundred.
