Thanks Pizza Bob. Seems strange that FFL can't simply ship it to manufacturer w/o all this extra paperwork. Speaking with FFL, that's what I decided to do... Take possession and then ship to manufacturer myself. I was just trying to have the repair done while I wait for the new FID with my new address.
I just had a rifle come in and there is some defect that requires warranty repair. I didn't take possession of it yet (xfer+NICS), so when I asked the xfer agent to ship it to the manufacturer, they said that it would require a xfer to be done 3 times: to the manufacturer, back to the xfer agent and then to me (and thus 3x the fees) Is that true that xfer agent can't ship the firearm without doing this to/from xfers?
