Just submitted a Form 1 for a suppressor. What a mess. The ATF's website for submitting NFA forms is almost unuseable. Buttons don't work, scroll bars don't scroll, it times out, etc. They tell you that it's only compatible with IE 8, which no one who's remotely up to date would still be running. Leave it to the Feds.
Oh well, supposedly the online applications process quite a bit faster since the payment goes through right away.
