Airsoft: alternative/cheaper gas for GBB, tested, failed, mapp, butane, cooking, propane, lpg

Comments say Mapp gas is a horrible idea and the sulfer in these gases is so bad I won't be using them. Sadly I don't know of a source for odorless propane. The small airsoft cans seem very wasteful; they should sell larger bulk containers. #gbb #airsoft #gas
