Hello. I'm new to the forum so thank you in advance for any help. Does anybody know a good hack to go HPA on the air javelin that is using CO2? A bottle that would fit-adapters-etc... Thank you!!!

Welcome and there isn't any tried and tested ones that I know of besides a 12 gram co2 adapter and even Air Venturi already stated their HPA conversion won't work on this gun. There are manufacturers in England UK that may be of help if you do a search and reach out to them and I am sure someone there can make you a safe adapter for you to run a regulated tether line from a small tank. Good Luck.
