Somehow a way to send it out I paid like $60 for those repairs and upgrades and would not want to waste it. I'm stumped as to what to do and want help with how I could send it.
Where are you from? I'm going to assume 'Merica for the purpose of this post.
According to USPS regulations, you cannot send containers of gas (in this case, your gun's propane tank or whatever it uses). If you detach the tank, there should be no reason that it would go against USPS regulation.
However, according to lots of the internet (I Googled it and a bunch of Airsoft websites came around with answers), USPS is really weird about it and they really don't like it. UPS might be your best option (again, as long as you remove the gas thingy, it's perfectly legal).

Although this site says it IS illegal to send them assembled through USPS
