BrickArms have been leading the way in overmoulded LEGO compatible pieces and this Reloaded RPG-7 looks amazing. The rocket has a 1/16 steel pin for a rocket shaft, and inserts into the RPG7 tube. The exhaust end of the venturi (cone) is cored to accept any LEGO bar. This is entirely injected and there is no paint used anywhere.
