That sucks. There's a thread on ARFCOM full of folks going through your type of wait pain. No rhyme or reason to it either. Mine was individual, and I've never had a delay. Hope yours come in soon brother. You might try emailing
[email protected] with your control number. Some folks on ARFCOM are having good luck getting their stuff processed faster. Worth a shot.
Edit: Straight outta Google-Fu:
"To request an update on the status of an ATF NFA Form 4 background check, you can email the NICS Liaison. You should include your full name, Social Security number, date of birth, state of residence, submission date, serial number, manufacturer, model name, item type, and transferor."
Edit II: Ya know, I got to thinking about this.
I'd be very careful sending all that info via email. Unless it's highly encrypted. Might as well just send them the control number (as they should have all the info they need from that.) If they want more info, go from there. Just say'n..
