Klay,
Without a trust the suppressor is surrenderable to you local Sherrif or Police. It may be willed to another, kept in the estate, but the reciever must apply and recieve proper ATF transfer and tax stamp. Possession of a regulated item, here a suppressor (or an SBR, SBS, machine gun etc) fir which one does not have a stamp (linked to their name) is a felony. While now more difficult and expensive, a trust is a better bet for protecting your investment and your loved ones at the same time. Have your family member look into putting one together if they don't already have one.
