Okay before you drown me in co2, I'm thinking of filling paintball co2 canisters with propane and use one of these to fill up a GBB. Because the smallest propane tank in my country is this:
Aygaz tank
I checked their properties, propane doesn't cause any issues with the tank, but gotta see if o-rings cause any problems.
Just wondering if these co2 adapters fit into the filling port of gbbs aka are they same with nozzles of green gas bottles?
Thanks
