Form 1 vs Form 4: which NFA wait is longer?
Form 1 means you make the item yourself; Form 4 means you buy it from a dealer. They sound like paperwork details, but they put you in two different queues with very different waits. Here’s what 3,238 reported approvals show right now.
What the data says right now

Make or buy: what each form actually is
A Form 1 is an application to make an NFA item — turning a rifle you own into a short-barreled rifle, or building your own suppressor. You file before you build, wait for approval, then make the item. A Form 4 is an application to transferan existing item to you — the path you’re on when you buy a suppressor or SBR from a dealer. The dealer holds the item while you wait; approval is what lets you take it home.
The two forms sit in separate processing streams, and right now those streams move at very different speeds. The reason is recent: when the NFA tax stamp dropped to $0, filing went from a $200 commitment to free — and Form 1, the “make your own” route, absorbed a surge of new applications that Form 4 didn’t see. More filings against the same processing capacity stretched the Form 1 queue while Form 4 stayed comparatively steady.
The full story of the surge and what it did to the queue: NFA wait times after the $0 tax stamp.
One honest caveat: queues change. The gap you see above is today’s gap, computed live — it has widened before and it can narrow. For the current month’s figures across all four lanes, see this month’s NFA wait times.

Frequently Asked Questions
Which has the longer wait — Form 1 or Form 4?
Form 1, by a wide margin in current community data. For individual filers, Form 1 builds are running about 42 days longer than Form 4 dealer transfers. The gap moves over time — it grew sharply after the $0 tax stamp pulled a surge of new applications into Form 1 — so check the live figures above. Community data, not official ATF records.
What's the difference between Form 1 and Form 4?
Form 1 is an application to make an NFA item yourself — build a short-barreled rifle from a rifle you own, or make your own suppressor. Form 4 is an application to transfer an existing NFA item to you — typically buying a suppressor or SBR from a dealer. Both require ATF approval before you can legally make or take possession of the item, but they sit in different processing queues and their waits differ.
Why is Form 1 so much slower right now?
When the NFA tax stamp dropped to $0, the cost barrier to filing disappeared and application volume surged — and Form 1 absorbed the bulk of it, because making your own item went from a $200 gamble to free to try. More applications against roughly the same ATF processing capacity means a longer queue. Form 4 dealer transfers did not see the same surge and have stayed comparatively steady.
Should I build (Form 1) or buy (Form 4) a suppressor?
The wait is only one factor. Buying on a Form 4 gets you a commercially engineered suppressor and, in current data, a much shorter wait. Building on a Form 1 lets you make exactly what you want, but you wait longer and the finished product is only as good as your build. If your goal is simply owning a suppressor soon, the current numbers favor buying on a Form 4. If the project itself is the point, the Form 1 wait may be worth it to you.
Does filing as a trust change which form is faster?
No — the form-type gap dwarfs the owner-type gap. Trusts and individuals differ by days on the same form, while Form 1 and Form 4 can differ by months. Whether you file as an individual or a trust, Form 4 has been the faster form in recent community data. See our trust-vs-individual comparison for that separate question.
Can these waits change?
Yes — queues move. The Form 1 backlog reflects a specific surge of applications, and as the ATF works through it (or as volume shifts again) the gap between the forms will change. Every number on this page is recomputed live from 3,238 community-reported approvals, so what you see reflects current reports, not a snapshot from months ago. Our wait-times page tracks the current month's figures.
Where do these numbers come from?
Every figure here is drawn from approvals that NFA filers reported to NFA Watch — currently 3,238 of them. It is community-sourced data, not official ATF or government records, and it reflects a sample. Medians shift as more filers report.
NFA Watch is an independent community project and is not affiliated with the ATF or U.S. government. All data is self-reported by NFA filers and reflects community observations — not official ATF records. Approval times vary. Nothing here is legal advice; consult a qualified NFA attorney about the requirements for making or transferring NFA items in your situation.
