According to a reader at The Firearm Blog, the eForms system isn’t the only part of ATF’s NFA branch that has ground to a halt during the government shutdown.

I called [the BATFE] today and Vicky (a pleasant sounding lady who answered the phone) said they have been affected by the government shutdown.  Staff furloughed, no applications are being processed, nor can they check status.  My Form 4 was sent in Feb 2013, so who knows when I’ll see it.

If you weren’t planning to spring for delivery confirmation for your application submissions before, now would be a good time to reconsider, especially if you are using a trust or business entity to register NFA firearms and trying to get applications in before the proposed regulations can take effect.
