The regulatory landscape around NFA firearms has shifted significantly over the past decade. If you're relying on information you read a few years ago — or advice from a friend who bought a suppressor in 2019 — you may be working with an outdated picture. Here are the most important rule changes in plain language.
ATF Final Rule 41F (2016): The Trust Rule Change
For years, gun trusts had a significant advantage over individual ownership: trust applicants didn't have to get a CLEO signature, and trustees weren't subject to individual background checks. ATF Final Rule 41F changed that, effective July 13, 2016. The major effects:
- Background checks for all responsible persons: Every trustee named in a gun trust must now submit fingerprints, photographs, and a Responsible Person Questionnaire (ATF Form 5320.23) for each new NFA application.
- CLEO notification, not signature: Individual applicants used to need a CLEO's actual signature — which some officials refused to give. Rule 41F changed this to notification only. You send a copy of your application to your CLEO. They can't block it.
- Same process for individuals and trusts: The background check requirements are now largely equivalent. Both go through the ATF; both require fingerprints and photos.
What this means today: If you have a gun trust from before 2016 that was drafted specifically to avoid the old CLEO requirement, it's worth reviewing with an attorney. The legal landscape it was designed around no longer exists in the same form.
The One Big Beautiful Bill Act (2025): Tax Stamp Eliminated
This is the biggest NFA reform in nearly 90 years. Signed into law on July 4, 2025, the One Big Beautiful Bill Act reduced the federal NFA transfer tax on suppressors, SBRs, SBSs, and AOWs to $0, effective January 1, 2026.
For context: the original $200 tax was enacted in 1934, when $200 was roughly equivalent to $4,000+ today. It was deliberately designed to be prohibitive.
CHANGED: The $200 federal NFA transfer tax is now $0 for suppressors, SBRs, SBSs, and AOWs. · NOT CHANGED: ATF Form 4 is still required. Background checks still required. Fingerprints and photos still required. CLEO notification still required. State laws still apply. Machine gun and destructive device taxes unchanged ($200).
eForm Processing: The Speed Revolution
Separate from legislative changes, the ATF's shift to electronic Form 4 submissions has dramatically reduced wait times. Paper Form 4s still take around 286 days. Electronic submissions are currently processed in days — typically 4–11 days for individuals and 18–26 days for trusts in 2026, though these figures shift month to month based on ATF volume and staffing.
What to Watch Going Forward
- Some advocates are pushing for suppressor deregulation — removing them from the NFA entirely, not just eliminating the tax
- The Hearing Protection Act has been reintroduced in various forms over the years with this goal
- ATF budget changes and staffing levels can affect processing times, regardless of what the law says
- State laws continue to vary — some states have banned NFA items regardless of federal changes
Firearms law moves. What's current today may change next year. Working with an attorney who follows this area closely is the best way to stay informed and stay compliant.
