Why are you doing an FFL trainer in the first place ? You built it as a Graduation present right? Just give it to him as a gift. We have no gun registration hear in La.
I would hazard a guess that the OP is in another state, not convenient to Louisiana. As such he cannot simply send it by mail or put it on a Greyhound bus.
He will need to do an FFL transfer presuming the above is the case.
Remember, you can never transfer a firearm directly to another person who is a resident of a different state. In that case, you must transfer the firearm through a licensed dealer in the state where the person receiving the gift resides.

A person may only acquire a firearm within the person’s own State, except that he or she may purchase or otherwise acquire a rifle or shotgun, in person, at a licensee’s premises in any State, provided the sale complies with State laws applicable in the State of sale and the State where the purchaser resides. A person may borrow or rent a firearm in any State for temporary use for lawful sporting purposes.
