Since 2025, the Trump administration has been rolling back a wide range of gun regulations enforced by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Since April of this year, there have been roughly three dozen proposed and final rule changes, along with new lawsuits against state and local gun laws, that together amount to the most sweeping re‑write of ATF policy in years.
It’s a lot to keep up with, so FindLaw has put together a practical summary of what is changing and why it matters. Below is an overview of the main policies being unwound and the practical effects they’ll have.
From Zero Tolerance to a Higher Bar
First, some history.
Under the Biden administration, ATF adopted a “zero‑tolerance” policy that made it much easier to revoke the licenses of federal firearms dealers who repeatedly broke the law by skipping background checks, falsifying records, or selling to prohibited buyers. That policy led to a sharp increase in license revocations and signaled that even repeated paperwork‑related violations could carry serious consequences.
ATF has described its work under the Trump administration as a “new era of reform” focused on closer partnership with the firearms industry. As part of that shift, the agency ended its Enhanced Regulatory Enforcement Policy and, in May 2025, replaced it with a more forgiving Administrative Action Policy. It also created new industry‑facing roles and a classifications board, and invited dealers whose licenses had been revoked under the old policy to reapply.
Dealer Protections and Reduced Oversight
Under the new Administrative Action Policy, ATF generally must show that a dealer knew it was violating the law before pulling a license. The administration says this is meant to keep “immaterial paperwork errors” from costing dealers their licenses, and that same logic shows up in how ATF oversees dealers more broadly.
The new regulatory package also eases the burden on dealers by trimming back inspection tools and reporting obligations. ATF is revising how inspection and compliance data are published, narrowing when and how the agency shares information about dealer violations and enforcement outcomes.
At the same time, the administration and allied gun‑rights groups are pushing for looser rules on how long federal firearms licensees must retain sales records and how the government can use those records. Some proposals simply revert to pre‑Biden standards; others go further, arguing that long‑term record retention creates an “effective registry” of gun owners. Taken together, these changes are meant to give dealers more breathing room but also limit the data ATF can use to trace guns and spot patterns of unlawful sales.
Private Sales and the Gun Show Loophole’
One of the most visible rollbacks targets Biden‑era rules designed to narrow the so‑called gun show loophole. Those rules had expanded the circumstances in which private sellers at gun shows or in other informal settings had to run background checks, especially when they were effectively operating like dealers or when sales were likely to be straw purchases.
As part of its 2026 regulatory package, the Trump administration has moved to undo those requirements. In doing so, it’s restored the world in which private firearm transfers can take place without any federal background check so long as the seller is not a licensed dealer.
Supporters argue that this respects long‑standing practices for private sales and prevents casual sellers from being swept into dealer‑level regulation. Opponents warn that it reopens a significant channel for firearms to move into the hands of prohibited buyers without any screening.
Loosening Mental Health Restrictions
Another key area of rollback involves how federal law treats people with certain mental‑health histories or financial‑capacity determinations.
Under Biden‑era policies, individuals reported as unable to manage their own finances or subject to certain mental‑health findings could be flagged and barred from buying or possessing firearms. Agencies such as the Department of Veterans Affairs fed those determinations into the background check system.
The Trump administration has moved to narrow those categories. In practice, that means people who voluntarily admit themselves to mental‑health facilities are less likely to be automatically swept into gun‑prohibition categories. It also means that individuals who need a fiduciary to manage benefits or finances will not necessarily lose gun rights solely on that basis.
ATF’s own analyses have acknowledged that loosening these restrictions could raise public‑safety risks “up to and including potential mass‑casualty events.” At the same time, the Trump admin claims that prior rules were overbroad and unfairly stigmatizing.
Stabilizing Braces, Short‑Barrel Rifles
The administration is also rolling back rules that treated certain accessories and rifle configurations as especially dangerous.
Under Biden, ATF tightened scrutiny of stabilizing braces (devices that can make pistols function more like short‑barreled rifles) and of some short‑barrel rifle setups. The theory was that these devices produce weapons that are more concealable yet highly lethal.
Those rules are now being reversed or re‑interpreted to be more permissive. The stated justification is that prior regulations went beyond statutory limits and did not reflect recent Supreme Court guidance on how far agencies can go in expanding firearm classifications. But ATF itself has recognized that broadening access to these configurations could create “dangerous, easily concealed weapons” that pose an increased public‑safety problem.
Suing States for Gun Restrictions
Some of the most significant rollbacks are indirect: instead of just changing ATF’s internal rules, the Trump administration is attacking state and local gun laws that go further than federal standards. The Department of Justice has brought lawsuits against California’s handgun roster and restrictions on Glock‑style pistols, which state officials say are too easily converted into machine guns. The DOJ has also sued over assault‑weapon bans in jurisdictions like Virginia, Colorado, and D.C.
The Civil Rights Division, long associated with voting, housing, and school desegregation cases, is now being used to enforce gun rights, arguing that these state laws violate the Second Amendment. If the DOJ succeeds, or if the Supreme Court invalidates similar laws in pending cases, many state‑level restrictions that have been on the books since the 1990s could fall. This would effectively roll back another layer of regulation that ATF and its state partners have relied on.
In the end, these rollbacks don’t rewrite most gun laws; they rewrite how those laws work in practice. Whether that feels like long‑overdue relief or a dangerous rollback depends on where you sit in the debate over how far Second Amendment reform should go.
