How to Track NFA Items: Suppressors, SBRs, Form 1 and Form 4

Keep every suppressor, short-barreled rifle and other registered item in one place: what it is, which form it went in on, where that form stands, who it's registered to, the dates, and a copy of the tax stamp you can pull up when you need it.

NFA paperwork has a way of ending up in three places: the stamp in a safe, a PDF in a downloads folder, and the approval date in your memory. When you're waiting on a Form 4, you want to know how long it's been. When a stamp is approved, you want the record and the copy together, next to the firearm it belongs to. Everything in this guide is from a real account with five NFA items, including a Serbu Super Shorty AOW, a Spikes Tactical 37mm launcher held in a trust, and a registered DIAS.

GunCollector is a record-keeping tool, not legal advice. It stores what you enter and what it reads from your paperwork. It doesn't tell you what's legal, what form you need or how to transfer an item. For the rules, go to the ATF.

1. The NFA items page

Open NFA items. Each card shows the item's status, its type, form and ownership (with the trust or corporation name), the serial number and the dates you've recorded. Search by make, model or type, filter with the type chips, and sort by Name, Date or Status.

NFA items, 5 NFA items, with Import Form 1 and + Add NFA item buttons, a search box, type chips from All types to Registered sear, and sort by Name, Date or Status. Under Suppressors and devices: Registered DIAS Drop-In Auto Sear, Approved, Form 4 (Transfer), Corporation, Example Holdings LLC, approved Jun 11, 2019; Serbu Super Shorty, Approved, AOW, Form 4 (Transfer), Individual, submitted Jan 9, 2023, approved Aug 22, 2023; Spikes Tactical 37mm Launcher, Approved, Destructive device, Form 4 (Transfer), Trust, Summit Ridge Trust, approved Oct 4, 2022
Every NFA item, with its status, form, owner and dates.

The list is split in two: Suppressors and devices, and NFA firearms. On each card, the camera icon opens its photos and the pencil edits it.

2. Add an item: devices and NFA firearms

Click + Add NFA item. You can start from a photo (Take or Upload Photo, covered below) or click Enter manually. Either way you land on the form, which starts with the NFA type. There are eight:

Suppressors and integrally suppressed firearms also get a Caliber.

Add NFA item: NFA type with eight choices and SBR selected; the note NFA firearm, link to a firearm in your collection, or add a new one below; Firearm in your collection with Link existing selected and a Select firearm menu, or + Add new firearm; Manufacturer on ATF form (optional), only needed if the ATF paperwork lists a different manufacturer than the firearm itself
An SBR is linked to a firearm in your collection.
Further down the same dialog: Form type Form 4 (Transfer), Form status Not submitted, Ownership Trust, Trust name with the example Smith Family NFA Trust, date fields for Submitted, Approved and Transferred, a note that valuation for NFA firearms is tracked on the linked firearm's record, and Notes
The paperwork: form, status, owner and dates.

For an NFA firearm, choose Link existing to pick a firearm you've already added, or + Add new firearm to create it in the same step. For an SBR, SBS or machine gun, the make, model and serial number come from that firearm, so you don't keep them in two places. An integrally suppressed firearm keeps its own make, model and serial for the suppressor. A firearm can have only one NFA item, and if you delete the NFA item later, the firearm stays in your collection. A firearm you create here counts toward the Free plan's 5 firearms.

If the ATF paperwork lists a different maker from the one on the firearm (an importer, or whoever did the SBR or machine gun conversion), put it in Manufacturer on ATF form (optional). Leave it blank otherwise.

3. Record the paperwork

The rest of the form is the paperwork, as it appears on your approved form or as it stands today:

For a device, there's a valuation section for what you paid and what it's worth. For an NFA firearm, the value lives on the linked firearm's record, as the dialog notes: set the price and estimated value on the firearm's page in your collection. Add anything else in Notes, then click Add NFA item.

4. The item's record and the wait

Click an item to open its record. It has the registration details, the valuation for a device, and a form timeline that fills in as each date is recorded.

The Serbu Super Shorty record: Approved, AOW, Form 4 (Transfer), Individual. Registration: serial number SRB-SS-2201, manufacturer per ATF form Serbu Firearms, Form 4 (Transfer), Individual. Valuation: purchase price $1450.00, est. value $1600.00, valuation basis Manual estimate. Form timeline: Submitted 2023-01-09, Approved 2023-08-22, Transferred not yet recorded
An approved AOW: registration, value and form timeline.

While a form is still waiting for approval, the top of the record counts the days for you: ⏳ N days since submission — still waiting for approval. No more digging for the date you hit submit.

For an NFA firearm, the record also links to the firearm itself with View firearm in collection, and its gallery shows the firearm's photos first.

5. Keep a copy of the tax stamp

At the bottom of the record is Photos & Documents. Pick a category, click + Add photo, and drag to reorder. The categories are Item photos, Serial number, Paperwork / tax stamp and Receipt. NFA items take PDFs as well as photos, so the approved form you downloaded can go straight in.

Photos and Documents on the Serbu Super Shorty: a category menu set to Item photos, + Add photo, Drag photos to reorder; two placeholder images, the main item photo labeled Item photos and a tax stamp image numbered 2023-A-990120 labeled Paperwork / tax stamp
The item photo and the tax stamp, side by side.

A Receipt does more than sit there: the price on it fills in the item's value. For an SBR or other NFA firearm, that value goes to the linked firearm.

6. Add an item from a photo

In the add dialog, click Take or Upload Photo and give it a photo of the item or of its paperwork. While it reads, you'll see Identifying NFA item…, then the form opens with what it found filled in. Check every field before you save: it's reading a picture, and you know your item better than it does.

A photo of paperwork isn't thrown away once it's read. It's filed on the new item under Paperwork / tax stamp, so your copy is already in place.

7. Import a Form 1 from ATF eForms

Built it yourself? If your Form 1 went through eForms, you don't need to type it in. Click Import Form 1 on the NFA items page, download your approved Form 1 from eforms.atf.gov, and drop the PDF in.

Import from ATF eForms: download your approved Form 1 from eforms.atf.gov and upload it here, we'll read the fields automatically; a drop zone reading Drop PDF here or click to browse, ATF Form 5320.1 (approved Form 1); Cancel
Upload the approved Form 1 PDF from eForms.

It takes the approved Form 1 (ATF Form 5320.1) as a PDF of up to 10 MB. You'll see Reading your Form 1…, then a review of what it read: the barrel length, overall length, ATF control number and dates, and the firearm record. If anything looks off, it's flagged with a Heads up: note. Read those, fix what needs fixing, and save.
