With an ATF rule eliminating the $200 NFA tax stamp fee taking effect in less than a week and two landmark Supreme Court decisions expected before the end of June, gun owners and transfer professionals face a packed calendar of legal changes. No breaking headlines arrived overnight, but several high-impact developments from recent weeks remain active and compliance-critical.

Today’s Headlines

• ATF NFA Tax Stamp Rule ($0 Fee) — Effective June 10: A final ATF rule implementing the statutory reduction of NFA transfer and making taxes to $0 for suppressors, short-barrel rifles, and short-barrel shotguns (excluding machine guns and destructive devices) takes effect in six days.

• SCOTUS — United States v. Hemani (Marijuana & Gun Possession): A decision is expected by late June on whether the federal prohibition on firearm possession by unlawful drug users violates the Second Amendment; the Fifth Circuit had struck the law down. Source: scotusblog.com
• SCOTUS — Wolford v. Lopez (Carry on Private Property): Also expected by late June, the Court is reviewing Hawaii’s law presumptively banning firearms on private property open to the public, with potential national implications for default carry rights in businesses. Source: scotusblog.com
• ATF “New Era of Reform” — 34-Rule Overhaul Package: The DOJ and ATF announced 34 final and proposed rules in late April, including formal repeal of the stabilizing brace SBR reclassification, removal of the bump stock machine gun classification, and rollback of an expanded FFL licensing rule.

• USPS Handgun Mailing Ban — Proposed Rule Open: Following a January DOJ opinion declaring the 1927 handgun mailing ban unconstitutional, USPS published a proposed rule on April 2 that would allow lawful handguns to be mailed under conditions similar to those for long guns; interstate commercial transfers still require FFL processing.

• Colorado Semiautomatic Ban & Permit-to-Purchase — Effective August 1: Colorado’s SB25-003 bans the sale and transfer of specified semiautomatic firearms with detachable magazines beginning August 1, 2026, and adds a Firearms Safety Course Eligibility Card requirement for purchases; a minimum age of 21 for ammunition purchases takes effect July 1.

• Rhode Island Assault Weapons Ban — Effective July 1: Rhode Island’s S 359, signed in 2025, takes effect July 1, 2026, restricting manufacture, sale, purchase, and possession of assault weapons, with a grandfather exemption for lawfully owned firearms. Source: uscca.com

What This Means for Gun Owners

The June 10 ATF rule is the most immediate action item for FFL dealers and NFA transferors — forms and fee processing should reflect the $0 tax for eligible items starting that date. The two pending Supreme Court rulings could significantly alter federal eligibility standards and state-level carry regulations within weeks; dealers in all states should monitor those decisions closely. Gun owners and dealers in Colorado and Rhode Island should review inventory and transfer procedures now, ahead of July 1 and August 1 effective dates.

Key Dates to Watch

• June 10, 2026: ATF NFA $0 tax stamp rule takes effect for suppressors, SBRs, and SBSs
• Late June 2026: SCOTUS decisions expected in Wolford v. Lopez and United States v. Hemani
• July 1, 2026: Rhode Island assault weapons ban takes effect; Colorado ammunition age minimum (21) takes effect
• August 1, 2026: Colorado semiautomatic firearm ban and permit-to-purchase requirement take effect
