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, and at times very different waits. Here’s what 118 e-file approvals reported in the last 30 days show 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. If you file one, 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 they can move at very different speeds. For most of 2026 they did: 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 Form 1 · Individual median climbed to 69 days by Jun 2026 and has since come down to 3 in Sep 2026.

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?
Right now the two forms are running effectively even in community-reported data. That can change quickly — the gap between them has been large at times, so check the live figures above.
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. Until October 9, 2026, ATF required an approved form before you could make or take possession of a suppressor or SBR. As of that date ATF says filing is voluntary for suppressors, SBRs, SBSs and AOWs, but it still processes both forms, many states still require federal registration, and machine guns are unchanged. The two forms sit in different processing queues and their waits differ.
Why did Form 1 fall so far behind Form 4?
When the NFA tax stamp dropped to $0, the cost barrier to filing disappeared and application volume surged. Form 1 absorbed the bulk of it, because making your own item went from a $200 gamble to free to try, and more applications against roughly the same ATF processing capacity is what lengthened the queue. Form 4 dealer transfers never saw the same surge and moved far less. The Form 1 · Individual median climbed to 69 days by Jun 2026 and has since come down to 3 in Sep 2026.
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; building on a Form 1 lets you make exactly what you want, and the finished product is only as good as your build. In current data the two forms clear at about the same speed, so the wait is not a reason to pick one over the other right now. That has not always been true: for most of 2026, building meant waiting months longer.
Does filing as a trust change which form is faster?
It can. For most of 2026 the form mattered far more than the owner type: at the peak, Form 1 and Form 4 differed by months while trusts and individuals on the same form differed by weeks. Right now both gaps are small: about 0 days between the forms and 1 between trusts and individuals. See our trust-vs-individual comparison for that separate question.
Can these waits change?
Yes, and they have. Form 1 built up a backlog after the $0 stamp surge early in 2026 and worked most of it off in July and August, which moved the gap between the forms by months. Every number on this page is recomputed live from 118 e-file approvals reported in the last 30 days, 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 reported by NFA filers — 118 e-file approvals in the last 30 days behind the medians above, out of 4,333 reported overall. It is community-sourced data, not official ATF or government records, and it reflects a sample. Medians shift as more filers report.
