Ok so I am actually going to answer my own question. Just to help those others who have the same problem as me. And let me tell you this information was not easy to find.
Anyway I found that you could purchase these parts on wgcshop.com. However, they are all out of stock. For now I am just going to wait for them to come back in stock though I fear it could be awhile. So if anybody knows any other place to get them that would be great!
Ok so I am now going to add more to the answer of my own question. I have found that you can also buy these parts at airsoftgi.com and redwolfairsoft.com they are steel ones just like the ones from wgcshop.com and just like those they are also out of stock. They are Deep Fire brand but there is also a Falcon brand and both are available at ehobbyasia.com and are currently in stock there. Took me awhile to find these answers on my own :)
