Best way to finish an 80% lower?

For the record if you didn't build it with the intent to sell it you can sell it later.
Personally, I don't see the point in finishing one unless I wanted a certain or no rollmark.

Off the books? I'm pretty sure most people that order anything gun related off the internet are on some kind of list.

Easy to finish just get a jig and Borrow a drill press (unless you have one) and do it your self.
I have finished these and they look and function perfect.
