For 30 years the answer to “how long does it take to buy a suppressor?” was “sit down.” Nine-month waits. A $200 federal tax on top of the can. Paperwork thick enough to shim a door. In 2026 that story is basically over. The federal tax stamp dropped to $0 on January 1, and eForm 4 approvals are running in days rather than months. If you’ve been putting this off, the wait finally ends.

August 2026 Update  / A federal court struck down NFA registration for suppressors on August 5, 2026, and as of September 8, 2026 the Justice Department has not appealed. It is not a nationwide repeal, and it does not change anything for Colorado buyers — the Form 4 process below still applies exactly as written. Read our full breakdown of the ruling and where Colorado stands.

What Actually Changed in 2026

  • $0 tax stamp — the $200 NFA transfer tax was zeroed out by H.R. 1, the “One Big Beautiful Bill.” Effective for Form 4s submitted on or after Jan. 1, 2026. Machine guns and destructive devices are still $200.
  • eForm 4 is fast again — Silencer Shop’s public tracker put the median at roughly 3 days for individuals and 10 days for trusts as of September 6, 2026. ATF’s own published averages run longer; the two measure different things.
  • Paper Form 4 is effectively dead — still technically allowed, but published estimates for paper range from months to years depending on whose numbers you read. Nobody files paper anymore.
  • Everything else is the same — you still need a Form 4, a background check, and a licensed dealer transfer. Registration didn’t go away, just the tax.

02The Six Steps

Step 1

Pick the Can

Choose a suppressor sized for your host firearm and caliber. We’ll show you what fits your rifle, pistol, or shotgun.

Step 2

Buy It From Us

Pay for the suppressor at Elk River Guns. It stays in our safe until the ATF approves the transfer to you.

Step 3

Fingerprints & Photo

Two sets of prints and a passport-style photo. Done in-store on the kiosk, no mail-in prints.

Step 4

File eForm 4

You file electronically as an individual or trust. Include a “responsible person” packet for each trust member.

Step 5

Wait for Approval

ATF emails you when it clears. Timelines are theirs, not ours — see the tracker note above. We’ll reach out when it lands here.

Step 6

Pick It Up

Bring your ID. We do the final 4473 transfer in-store, hand you the approved stamp, and it’s yours to take home.

Days instead of months, and no federal tax. If you’ve been telling yourself you’d get one “when things settle down” — they did.

03Individual vs. Trust — What’s the Difference?

The single biggest decision on your Form 4. Both are legal. Both work. They answer different questions about ownership and about who is permitted to possess the can — and those possession questions are genuinely legal ones, so here’s the shape of each rather than a recommendation.

File as an Individual

  • Fastest median right now.
  • Simplest paperwork — just you.
  • One registered owner, and the rules on who else may possess it are narrower.
  • On death, it passes through your estate.

File as a Trust

  • Slower median right now.
  • Multiple trustees can be named on the trust.
  • Succession is handled by the trust document.
  • Trustees can be added or removed over time.
Which one is right for you is a legal question, and we’re not the ones to answer it. Possession, lending, travel and estate handling all turn on details we can’t evaluate at the counter. Talk to an attorney who works in NFA law before you decide. We’ll process either one.

04What About Colorado?

Colorado allows suppressor ownership, and CPW’s regulations permit suppressor use when hunting big game, predators, small game and furbearers. Colorado adds no state permit or state registration on top of the federal process. The current CPW regulations are the authority on manner of take for your season — read them, or call CPW, before you hunt with one.

CPW Note  / Follow all standard Colorado Parks & Wildlife regulations for your hunt. The suppressor is a firearm accessory — the underlying rules for weapon type, caliber, and season don’t change because you added one.
SB25-003 is written around the underlying firearm. C.R.S. 18-12-116 defines a “specified semiautomatic firearm” by action type and magazine — a suppressor is not a firearm under that definition. If you’re building a suppressor-host rifle, the question is about the host, not the can. See our SB25-003 guide, and take anything unusual to a Colorado firearms attorney.
