The propane adapter will only fit the type on tank that I posted a photo of which has a screw thread
It also is loaded to a higher pressure than tha propane/butane mix

I used propane for a while often shooting from my kitchen out into the back garden and it smelled just awful

I stopped using it as the cost of propane increased and the saving was not worth the bother of oiling the mags and putting up with that terrible smell

havn't use the propane gas yet don't know about the smell but yes indeed the price on propane is very high 400gram is like 18euro and the green gas in my local airsoft store is only 11euro for 570ml
