What is the weakest gas avaliable for a tokyo marui desert eagle .50 ae hardkick bas blowback?

Question

i was wondering which one would hurt the less!

Answer 1

Green gas is really your only choice because Red gas would blow the seals and ruin your gun. My advice, get a tactical vest over a couple of t-shirts and you should barely feel it ( in the right spots)

Answer 2

hfc 134a is weaker than green gas and is the gas that you should be using anyway.
