The Final Comment Window Is Closing on ATF's 34-Rule Package. Here's What Happens Next.

ATF's April 2026 deregulatory package is one of the broadest coordinated regulatory packages ATF has issued — stabilizing braces, Form 20 travel approval, CLEO notification, spousal registration, interstate transport, and more. With the public comment periods now closing, the package enters the phase most gun owners have never seen up close: comment response, final rules, effective dates, and near-certain litigation. None of the proposed changes discussed below is effective yet.

How We Got Here

In February 2025, Executive Order 14206, "Protecting Second Amendment Rights," directed the Attorney General to examine all agency actions for ongoing infringements of Second Amendment rights and to propose a corrective plan. ATF's answer arrived in stages: a first tranche of six NFA-focused proposed rules in May 2026 — covered on this site in Proposed ATF NFA Changes: What to Know — followed by the agency's announcement of a package comprising 34 final and proposed rulemaking actions, with comment periods concentrated in the first week of August 2026. Not every item is a proposal: at least one final action, the revised bump-stock definition, took effect May 6, 2026.

The comment phase is now closing. What follows is a guide to the phase that starts next — because the distance between "proposed" and "enforceable" is where most of the misinformation in this space lives.

The Proposals That Matter Most for NFA Owners

Stabilizing braces (ATF No. 2025R-11P)

ATF proposes removing from the Code of Federal Regulations the definitional language added by the 2023 brace rule. That proposal would not newly suspend an otherwise operative rule: a federal court universally vacated the 2023 rule in June 2024, and ATF acknowledges that it has effectively not been enforced. Finalization would principally conform the regulatory text to the vacatur and restore classification under the statutory definition and pre-2023 case-by-case framework.

Comments closed August 4, 2026. See Mock v. Garland, No. 4:23-CV-00095-O, 2024 WL 2982056 (N.D. Tex. June 13, 2024); the government dismissed its appeal in July 2025, leaving the vacatur in place.

Form 20 / short-term interstate travel

ATF proposes eliminating the approval requirement for short-term interstate transport of registered NFA firearms — trips of 365 days or fewer would require no notice and no approval. This is arguably the highest quality-of-life improvement in the package for ordinary NFA owners who travel to hunt, compete, or train.

Comments close August 6, 2026. Until a final rule publishes, an approved Form 20 (or 5320.20) remains required for interstate movement of SBRs, SBSs, machine guns, and destructive devices. Suppressors remain outside the Form 20 requirement, as before — but state law at your destination always controls, and that trap is unchanged by anything in this package.

CLEO notification removal

ATF proposes deleting the requirement that Form 1 and Form 4 applicants forward copies to their chief law enforcement officer — the last vestige of the pre-2016 CLEO sign-off regime that Rule 41F replaced.

Comments closed in early July 2026. Low controversy, high paperwork relief; a plausible candidate to finalize early.

Joint spousal registration

ATF proposes allowing married couples to jointly register NFA firearms without forming a trust. I analyzed this candidly when it was proposed: it competes directly with one use case for a gun trust — and only that one. Two spouses, shared possession, nothing more. It does not reach other family members or authorized users, does not address incapacity, and does not manage the estate transition the way a trust's successor-trustee structure does.

Comments closed July 7, 2026. See $0 NFA Tax: Do You Still Need a Gun Trust? for the fuller decision framework.

Interstate transport clarification (ATF No. 2025R-18P; RIN 1140-AA73)

A Gun Control Act proposal codifying protections for interstate transport of firearms — with the practical effect of clarifying coverage for scenarios like overnight stops, and for magazines and accessories, that the Firearms Owners' Protection Act's safe-passage provision has long left contested.

Comments closed August 4, 2026. A federal regulation does not erase generally applicable state prohibitions, but a valid federal safe-passage rule may preempt contrary state enforcement during transportation that falls within its protected scope. The boundaries of that protection — particularly for magazines, accessories, and overnight stops — may still be litigated.

The rest of the package

The remaining items span Form 4473 retention limits for dealers (proposed 20- or 30-year caps), a first-ever regulatory definition of "straw purchase," machine gun transfer processing changes, special occupational tax clarifications, and dozens of smaller cleanup actions. Not all of them are deregulatory in effect, and several — the straw purchase definition in particular — drew opposition comments from major gun-rights organizations urging withdrawal.

Comment periods varied; most closed by August 6, 2026.

What Actually Happens Now: The Rulemaking Process From Here

The Administrative Procedure Act governs everything from this point forward, and it imposes real work on the agency:

Comment review and response. ATF must consider significant comments and articulate reasoned responses when it finalizes. For a package that drew heavy public participation — the agency's proposals generated substantial comment volume across the board — this is not a rubber stamp. An agency that ignores a serious comment hands challengers an "arbitrary and capricious" argument under the APA.

Final rules, published in waves. There is no statutory deadline for finalizing, and a 34-item package will not finalize as a unit. Expect the low-controversy paperwork items to move first and the contested definitional changes — braces, straw purchases — to take longer and emerge with lengthy preambles built to survive judicial review.

Effective dates. Final rules typically take effect no sooner than 30 days after Federal Register publication, and major rules generally 60 days, subject to congressional review procedures. The operative rule of thumb for readers: the requirement in force today binds you until the day a final rule's effective date arrives — not the day a proposal is announced, and not the day a final rule is signed.

Litigation. Assume the most consequential items get sued from one direction or the other. A finalized straw-purchase definition invites challenges from gun-rights organizations, and contested definitional changes invite challenges from the other direction. Courts can stay final rules pending review, which can add months or years before a published rule ever binds anyone. The 2023 brace rule's own litigation history — challenged, enjoined in part, then vacated outright before ATF ever meaningfully enforced it — is the cautionary tale.

The Jensen Wild Card

On August 5, 2026 — the same week these comment windows close — a federal district court in Texas held the NFA's registration scheme unconstitutional as applied to untaxed firearms in the consolidated Silencer Shop Foundation and Jensen cases, permanently enjoining enforcement of the Form 1 and Form 4 requirements against those plaintiffs and their members and customers. I analyze that ruling in detail in A Federal Court Just Held the NFA's Registration Scheme Unconstitutional for Untaxed Firearms, but the interaction with this rule package deserves a note here. As of this writing no notice of appeal has been docketed, and at least one plaintiff has indicated it will seek to broaden the relief. Check the docket for appellate action before relying on anything below.

The judgment is not universal. It protects the named plaintiffs and, where applicable, their current and future members, customers, agencies, and political subdivisions. The court stayed the judgment for seven days, however, so no one should alter conduct based on the ruling while the stay remains in effect. The judgment also contains a separate standing-related limitation concerning AOW relief for the Jensen plaintiffs.

The ruling does not moot the rulemakings. For everyone outside the protected groups, ATF's forms remain the law, and the agency retains every institutional reason to finalize its package. If the reasoning survives appellate review and is later given broader effect, it could substantially reduce the practical importance of some NFA rulemakings. Until then, those rulemakings remain relevant outside the judgment's protected groups. Conversely, if the ruling is reversed, this rule package becomes the main event again. Anyone planning around either track alone is planning with half the map.

What NFA Owners and Trust Clients Should Do

Change nothing based on proposals. File your Form 20 before interstate trips with registered SBRs and other covered items. Send your CLEO copies. Proposals protect no one.

Do not assume every braced firearm is automatically lawful. The 2023 rule has been vacated, but individual configurations may still qualify as rifles under the statutory definition and preexisting classification principles.

Don't restructure your trust planning around the spousal rule. It is not final, and even finalized it addresses one narrow scenario. If a trust makes sense for your situation today, the pending rule is not a reason to wait — particularly with the tax at $0 and processing times short.

Watch effective dates, not headlines. When final rules publish, this site will cover which ones changed between proposal and final — agencies routinely adjust in response to comments, and the details that matter to owners tend to live in those adjustments.

Don't wait for the package. Realistically, some proposals may not become effective for many months, and some may never take effect if withdrawn or enjoined. If a Form 1, a Form 4, or a trust makes sense for your situation under the law as it stands today, deferring it in anticipation of a rule that may never arrive is a poor trade.
