There are advantages to a trust for sure.

If your wife is home alone and uses that firearm for self defense as a registered sbr it’s a felony( words spoken directly from a ATF officers mouth) if it’s only registered to you. On a trust you just add her too it with a very basic form as soon as you get the stamp in hand and she can legally posses it anytime

Say you wanna let your dad or brother go shoot it when your not there. Just add them to your trust. You don’t think this will happen but it does.

Easier to leave to your family when your gone.

If you really don’t see yourself ever needing trust protection or ease of transfer/adding heirs then do individual. Sbr stamp won’t take long either way. Saturday at class 3 dealer picking up a suppressor he said 8-12 weeks, with some coming back in 4-6 weeks.
