Hello I just got an airsoft forums account to ask questions about my guns. I am fairly new, but have a few guns. I own the CM042 AK47, C11 gas pistol, Cybergun famas, mossberg 590, and just ordered the WG XTREME SHOT 1911, and as the title says, the KWA MAC11. I know how to operate co2 guns, just stick the cartridge in and twist, but how do you use greengas guns? The Mac11 is green gas/propane. I want to use green gas, but have questions. What is the maintenance? I ordered a thing of G&G silicone oil for the gun, and where do I buy green gas? Please help. I need greengas, the silicone oil I have, and that's all I know. I think all you do from what I read is that you put silicone on the tip of the magazine, (where the bbs come out) and then pull back the bolt and put it in and your fine. Is that it? Please help I need detailed instructions! I don't want to bring this to a shop too much, and I don't know how to take it apart and upgrade, etc. thank you!!
