have you built on a stripped lower before?

dont know anything about the unfinished lowers myself but if you are willing to invest in the tools and spend the time then I think you should go for. can't beat having that kind of knowledge and experience these days. and with added expense you have from dealing with your FFLs it seems like this would be the most cost effective way to go if you plan to have multiple ARs.

sounds like a good thing to have under our belt. plus you keep your builds off the books.
