What's better co2 or green gas bbgun? And why?
Carbon dioxide guns are best because they have a lot of shots in a cartridge and the gas responds better in cold than propane. Most CO2 airsoft guns are cheaper than green gas guns. Check out www.airsoftblowbacks.com/Got-Gas--The-best-airsoft-propellant--CO2-or-Green-Gas- for details.
Most good guns use green gas like kea products, they make the best gas blowback pistols. I prefer green gas .
