OXYGEN GEN2 HPA Regulator

I previously uploaded the photos from my airsoft forums post haha* I have taken a step back from airsoft as of last year and I am trying to sell all my gear as I no longer play (the money is going toward a new car ;) ), I have plenty of photos so feel free to message for any more info! The parts is like, if not new . This is the price I would like to sell for, however I am open to offers :) (I want it gone haha) ALSO the price includes postage :)
