No. This was one of the benefits of a trust. You cannot loan your suppressor/SBR to someone else. <edit> Someone else can USE it in your PRESENCE... but the owner of the stamp has to be physically present. Thus, the idea that multiple people in control of a trust could use an item covered under a stamp issued to a trust SHOULD be ok. Again... not a lawyer - but this is how it was explained to me BY the lawyer who wrote my trust.
