I need some direction and my Google efforts left me with more questions than answers. I have one NFA gun in my possession that is already stamped. My adult son wants me to build an SBR for us to share and this probably won't be the last NFA item we add over the next 10 years or so. I'm guessing a gun trust is the logical step but I want to make this logical and easy.

My research leads me to follow this order:

1) get a trust with my current NFA item listed and myself as the sole trustee (leaving my son off of the trust for now),
2) add the SBR to the trust,
3) apply/receive the stamp on the SBR and assemble it
4) add my son as a co-trustee

Does that sound like the easiest and most logical play?

Any guidance is appreciated and no responses will be deemed legal advice or service.

Thanks, Brian.
