When I first got my license I informed my inspector that I wanted to build custom 10/22's. I was informed that I could only purchase complete rifles and change the parts. Buying only 10/22 receivers and then building a rifle would count as manufacturing. I believe this to be true with AR lowers as well. This is why so many dealers sells kits along side built out lower receivers, but not as complete rifles.
