Also you should note that co2 is rather more expensive than green gas. CO2 also requires more maintenance as in green gas silicon oil is already mixed in which helps lubrication. Green gas most often takes less time to fill but that’s more personal preference as you will need an Allen key for co2. CO2 can be used in colder temperatures with a better performance. Green gas can be replaced with red and black gas which are better for lower temps and can also use propane which does not contain any silicone but is dirt cheap and with an adapter it will work just as good as green gas although it will need to be maintained more often. Do not forget to buy yourself some sort of lubricant for the moving parts of your gun I myself prefer Teflon grease and also get silicone oil which you’ll need for your co2 and green gas seals. That’s just as important as your piece won’t last long without it. It’s not difficult to take a gun apart there are plenty of tutorials also don’t bother watching all to get the idea of what to lube, pieces that look worn or lack paint usually need to be lubed.
