I have the HurricanE HK416 / 417 stock and have had to rigg my own extention for the colapseable stock. Is there anyone out there that has the actual coil wire extention that would want to sell it. I am talking about the Coiled wire that connects the battery cable to the gearbox cable. This is needed since it colapses and extends but has little room to do so. I would love someone who has swaped out stocks on there hurricane kit to let me buy there coil wire from them. Here is a pic.
