How long is one good for and do you need one for each weapon?
It can be good for up to a year, which is what most folks set it for. Unfortunately it is not an eForm. You can put up to three items on one form and need two copies of each form you send in. It is really only needed for SBRs, SBSs, MGs, and DDs.
You are suppose to fill them out for each location you intend to travel to however I was told by BATFE person at NFA branch, that once it is filled out for a specific address in a state you can go other places in the same state with your items. Trying to get that in writing though.
I have some approved and returned in about 2-3 weeks and others take over 2 months to get back. Just curious if anyone has done any of these recently and what was their wait time.
