All I need done is to switch an upper receiver on my upper assembly.  Is there anyone here that could recommend someone or could do it for some $$$.  Just IM me and give me a price if you could.  

Thank you very much.

I'll do it free---if I ever get some time off work.

Let me know what you have---and line up parts before hand-------like a new roll pin for the FSB as I don't like to re-use those kind of cheap--disposable parts.

If its pretty much standard stuff----it won't take long at all to do.
