Thanks guys.
I might just go with the complete lower, then add the complete upper when I get the extra cash. If I order the complete lower, will I have to have it shipped to an FFL? Or can I have it sent directly to my house, I have a valid NC Concealed Handgun Permit, which allows me to bypass the NICS check? Also, how are the stock triggers on these things, is it worth the extra money for the 2 stage trigger?
