Now that we have SBR's, if you are planning a trip out of state and taking your SBR's or other NFA items (excluding suppressors), you need to get approval from the ATF using form 5320.20. here are some tips to help fill the form;
#1; If you have a trust for your NFA items, the trust name goes here, if not, your name.
#2: mark yes unless you plan on leaving the item at your destination.
#3: Important ATF will allow up to one year. (Ex: from 10-04-2014 to 10-03-2015) Then about 1 month prior to expiration, fill out another form for the next year and by time the expiration date arrives, you'll have your new approval for another year.
#4: name of the manufacturer as named on your form 1.
(serviceable) if the weapon is functionable enter yes, if not, enter no.
#5: Important This is what I entered on my form; Sport Shooting, Training, Lawful Hunting, All Lawful Purposes (If you are permanently or temporarily moving, enter moving to new residence).
#6: Location where NFA items are stored.
#7: Destination address. This can be a hotel, residence, or training venue, but be specific with the address.
#8: I entered Private Vehicles or Air Travel. Others have also entered Bus, Train, or other public and private conveyances just to cover everything.
#9 through #11 is if being exported out of the country.
#12 If a trust is named in #1, the Trustee would sign their name and add Trustee after the name. If no trust, the owner signs his/her name.
Mail it to the ATF at the listed address. In an emergency situation, you can call the ATF and they will give you a fax number to fax your application in, but they will mail it back by snail mail.
* Each destination requires a separate form and you can submit as many as you want.
*If you are outside of a "reasonable distance" from your direct path. In other words, lets say you are driving from Detroit to Orlando taking I-75 and your cousin Bob, who you want to visit, lives 140 miles west of I-75 in Somewhere Tn. That would be outside of of "reasonable distance" so a 5320.20 would be needed. But if Bob lived 15 or so miles from the direct route, that would be "reasonable distance".
What I did, was submit a form to a friend or relative's address in each state I would possibly be visiting during the year just to cover all bases. All of my forms were approved.
Note: Each form submitted must be done in duplicate with an original ink signature on each. You will be mailed back one copy of each form submitted
