hi all, i did some research in the faq and the search tool on asc and after all i'm still without answer to my question. so here it is, i own a FM HK416 but when people ask me wath's the brand... i usualy say its systema because most of the internals are it.. does full metal are made by airsoft company? or are they real receivers?
i also tried to search on google my uper receiver serial number and still no answer.
thank you all for the help
