The short version
Buying a suppressor in the United States is legal in most states (including Montana). It still requires an ATF background check, fingerprints, and a Form 4 application. What's different in 2026: there is no federal tax stamp anymore — Congress eliminated the $200 NFA transfer tax under the One Big Beautiful Bill Act, signed July 4, 2025, with the change taking effect January 1, 2026. Processing time has also collapsed — Form 4 approvals that used to take 6 to 12 months now average about 10 days through ATF eForms.
Common misconception: "Suppressors are illegal." False. They've been federally legal since 1934 and are owned by millions of Americans. They're regulated, not banned.
What changed January 1, 2026
The One Big Beautiful Bill Act eliminated the $200 federal transfer tax on suppressors, short-barreled rifles (SBRs), short-barreled shotguns (SBSs), and any-other-weapons (AOWs). Machine guns and destructive devices still pay the original tax. The paperwork itself didn't go away — Form 4 is still required — but the cost went from $200 to $0.
At the same time, ATF invested heavily in eForms processing throughput. As of mid-2026, Form 4 approval for individuals averages about 10 days; trusts typically take a few weeks longer. That's a dramatic drop from the pre-OBBB norm.
What still applies
- ATF Form 4 application — must be submitted for every transfer
- Two complete sets of fingerprints — one per applicant, plus per responsible person on a trust
- Passport-style photograph
- Federal background check (the same NICS check used for regular firearm sales, run as part of Form 4 processing)
- Notification to your Chief Law Enforcement Officer (your local sheriff or police chief)
- 21+ age requirement
- State-level restrictions (most states allow civilian ownership; CA, NY, NJ, MA, HI, RI, IL, and DC do not as of mid-2026)
Step-by-step — what to expect
1Pick the can
Match the suppressor to the host: caliber rating, mount system, weight, length, intended use. Common starting points are a centerfire rifle can (commonly 7.62mm rated for multiple cartridges) or a 22 caliber can for rimfire practice. Pistol cans are a separate category. We'll walk you through it if you haven't picked yet — different brands have different strengths.
For a deeper dive into the trade-offs (titanium vs steel vs Inconel, HUB vs proprietary QD, real decibel numbers), see our selection guide.
2Decide who owns it
You can title the suppressor to yourself (individual) or to an NFA gun trust. Both are valid; the right choice depends on who else you want to be able to legally possess it. Solo buyers usually go individual; families and shooting groups often choose a trust because every "responsible person" listed can use the can independently. We don't write trusts, but we can refer you to attorneys who do.
3Pay for the suppressor
Suppressor price up front. The $200 tax stamp is gone, so there is no ATF transfer tax anymore, and the application itself is free. We file your Form 4 in-shop at no separate charge when you buy the can from us. The one service fee is fingerprinting — a flat $50 per applicant for live-scan capture (details below and on our fingerprinting page).
4Fingerprints and photo
We take your prints and photo in-shop with live-scan digital capture — no ink, no cards — for a flat $50 per applicant, with an FBI-grade quality check before you leave. Trusts add the same for each responsible person. More on fingerprinting →
5We file Form 4 electronically
We submit through ATF eForms. The ATF acknowledges receipt within a few days. Then the wait begins — but it's a much shorter wait than it used to be.
6ATF processes the application
Current 2026 average: ~10 days for individuals, ~11 for trusts. Some applications clear in 3 to 5 days; complex trusts or flagged background checks can take longer. ATF posts current averages on their NFA Division dashboard.
7Approval — pick it up
When the ATF approves the transfer, we receive a stamped Form 4. You come back to Bozeman, we hand over the suppressor, you sign a final acknowledgement, and it's yours. Install it on your host, and you're done.
What it costs (typical Q3 2026 numbers)
- Suppressor itself: $500 to $1,500 depending on caliber, materials, modularity. New 3 D-printed flow-through designs are starting to ship at sub-$300 price points.
- Federal tax stamp: $0 (eliminated January 1, 2026)
- Fingerprinting: $50 per applicant (live-scan; Form 4 filing and vault storage during processing are included when you buy the can from us)
- Optional gun trust: $200 to $500 if you go with an attorney

Questions we hear a lot
Is there really no tax stamp anymore?
Correct. The $200 NFA transfer tax on suppressors, SBRs, SBSs, and AOWs was eliminated by the One Big Beautiful Bill Act, effective January 1, 2026. The change is not retroactive — applications submitted before then still owed the $200. Going forward: $0.
Why is the wait so much shorter now?
ATF invested heavily in eForms processing in late 2025 anticipating the post-tax-stamp buyer surge. Combined with reduced staffing demand on the tax-collection side (no more $200 stamps to process), throughput went up substantially. The current ~10 day average is consistent with what dealers are reporting nationally.
Can my spouse or kids use it?
If it's titled to you individually: only with you present and supervising. If it's titled to a trust: anyone listed as a responsible person on the trust can possess and use it independently. This is the main reason serious shooting families pick the trust route.
What states can you ship to?
Most states allow civilian suppressor ownership. As of mid-2026, the exceptions are California, New York, New Jersey, Massachusetts, Hawaii, Rhode Island, Illinois, and the District of Columbia. For out-of-state buyers in allowed states, the suppressor transfers through an SOT dealer in your state once the ATF approves — you pick up locally.
Why Northmark Arms?
We handle the Form 4 in-shop, follow up with ATF examiners directly, and keep you updated by phone or email. You talk to the person who handles your paperwork — not a call center. We build the host rifle too — the gun the can lives on — configured to your spec — most national suppressor sellers can't do that under one roof.
What if I want a suppressor and a custom rifle together?
That's exactly the kind of project we're set up for. We configure the rifle from your chosen components (action, barrel, stock, trigger, optic), assemble in-shop, and time the suppressor Form 4 to clear around the same time the rifle is finished. One quote, two transactions, one pickup.
