There is a temporary exemption that makes no sense as written. It allows a prospective transferee to temporarily examine or evaluate a firearm while in the presence of the prospective transferee.
I think they meant to write "prospective transferor" in the last two words; but that isn't what Thomas shows. Even some of the exemptions are hopelessly confusing, Dave Hardy was speculating that as written the "organized shooting range" exemption would not cover a range owned by an individual or partnership. The bill is a total mess.
