Tuning The co2 cartridge is stuck in the rifle! Help?!

Quick update:

Today I go replace the rifle, but I did contact the gun manufacturer. Surprisingly they're very helpful. They recommend that I only tighten it very carefully till I hear the gas being released. Over tightening was the main issue. But still, they said it's not my fault. I have a model manufactured in 2018 which does not have the window that could help push the cartridge outwards. Newer version does... Another thing is so many people are so generous on here as well. Warms my heart seeing people offer repairs and parts for free! You guys are awesome. I'll update you guys once I get the new rifle today. 
 
Good luck with the next one. Just remember to tighten it up just enough to where you hear the hissing stop. And if you don’t have any silicone oil, you should buy some. I don’t know if they have pellgun oil in your country.The seals can dry up if you don’t use it.Put one drop on the tip of the cartridge before installing.Just do not use a petroleum oil. At least you’ll get a rust free gun and keep it wiped down. 
 
I’m wondering how you are even finding CO2 cartridges and pellets. I guess you already checked where you bought the gun if they had any. If they don’t have any where you bought the gun, then see if they can order it themselves for you. I’m thinking maybe you should have bought another type of air gun. Like a break barrel single pump or a multi pump Airgun. Maybe you’ll find what you need eventually.
 
A lot of gun stores here in the United States does sell non-petroleum oils. It might not be silicone oil But the main thing is you don’t want petroleum based oil.Some people have used automatic transmission fluid in their CO2 guns. I have never myself but I have heard of other people using it.I don’t know if he’s awake right now but you could try private messaging Odoyle about that. He knows a lot about air guns. I only know certain things about them and will only Tell people what I can. But he is the one to ask that question about the automatic transmission fluid.
 
Just to elaborate here we had been corresponding through PM and had mentioned to use a rag barely damp with Alphabet org and run it inside the tube and on the outside of the Co2s so they slide easier in addition to the small drop on top where it pierces. It's more of a sure thing if the tubes are really tight fitting. Keep that damp Alphabet org rag in a glass container to use later when wiping the new Co2s before installing and whenever needed.
