I use SilencerShop.com as they have a nice eForms single-shot trust and their system is familiar to the ATF so it sails through. SilincerShop.com also publishes the daily wait times. For instance, today’s numbers say it takes between 1 to 143 days and a median 124 days right now. The ATF is processing about 1,250 approvals a day.
Good idea.
We brought thru our local FFL, and it was pretty quick, comparatively, back then, as compared to recent years.
