There is no green transfer port, what you see is the green seal inside the transferport.
There are 3versions, the black large opening, the UK market silver and the Match golden colour.
As the silver port is restricting the air flow too much, the gun uses/waistes too much air.
Increasing the diameter hole to say 4mm (easy as its plastic) will increase shot count ( and speed as well.
