The thing with Constructicon parts on eBay is that there are so many KOs. With the little guns, there is just no way to tell whether its an original or KO.
Nope. Don't think it works this way since I didn't buy it from a major retail store. I'm pretty sure exchanges are not possible, but also because little stores would not be able to correspondingly exchange with their suppliers.
In the greater scheme of things, I think I may not try (although know that I should).![]()
