Echo1 just re-brands guns like Cybergun and TSD do. In this case (the HK416), yes it's a re-branded JG. However, you aren't going to get trades with the Echo1.
The new ones you do. They just write "Echo1, Vector Arms" where the trades should be.
The JG 416 HAS HK trades on it. They are releasing/released a VFC version, Choate Stock, and a 14.5 with a full stock version.
