Looking to buy a Level 70 Kwik Change Thingy Rocket launcher

I’m on PS4. I’m willing to pay 50 million for a Legendary Level 70 Kwik Change Thingy Rocket Launcher. I been farming Iwajira for the last 3 days and haven’t found 1 legendary. So if your on PS4 and have one for sale i’ll pay 50 million. My PSN ID is Abaddon_81877.
