I have bought and sold guns--tractors, trucks, trailers and just stuff--for 50+ years and never signed or asked for a BOS. Bought one gun this week and sold 2. Handshake and visit a minute about guns and go home. If your britches cover your underwear, your hat is on right, look responsible, old enough to be responsible and you are driving a vehicle with Texas tags, then you are ok. Never has yet, but I might pass on a purchase or sale if required to do this crap. This is still a free countrY.
