Unless you are a veteran who brought back war trophy NFA arms prior to Dec. 1968 it would not apply to you.

My father brought back a Japanese rifle from Guadalcanal in 1945, if he wills it to me and it is not registered, what may happen?

If it is a machinegun or has a barrel shorter than 16 inches, if you get caught with it, you will go to FEDERAL PRISON and lose your right to vote and to own any kind of firearm.

If it is not fully automatic or has a barrel 16" or longer, then nothing, no big deal.
