Question regarding status as a dealer and "informal range transfers"

[sr71]

I keep getting conflicting answers on this: Can you transport a suppressor across state lines without the ATF approval, Form 5320???. Assuming it is legal in the state you are taking to.

I keep getting conflicting answers on this: Can you transport a suppressor across state lines without the ATF approval, Form 5320???. Assuming it is legal in the state you are taking to.

From the NFA handbook:

Section 13.8. Requesting permission to transport certain firearms in interstate or foreign
commerce. A person, other than an FFL/SOT, may not lawfully transport in interstate or foreign
commerce any destructive device, machinegun, short-barreled shotgun, or short-barreled rifle, without
prior written approval of ATF, specifically the NFA Branch.214 For definitions of these firearms and
devices, refer to 27 CFR 478.11. Licensed collectors are not required to obtain such approval if the
firearms and devices being transported are “curio or relic” firearms under the GCA. Approval for the
transportation may be obtained by (1) a written request or (2) an approved application filed with ATF on
Form 5320.20.

So in other words, the answer to your question is "yes."
