This is honestly my main qualm with the ATF rule recently. It's nearly impossible to NOT sell for a profit if you didn't buy something stupid just because most guns tend to hold their value and so they will naturally increase in value over what you paid for them due to inflation and market forces.I’ve seen my JM stamped Marlins (except my 30-30) going for double the price I paid for them 10 years ago.
I mean, it's one reason I don't hesitate to buy dumb stuff most of the time --- if I don't like it, it's not going to hurt me.
