IMPORTANT FOR DELAWARE GUN OWNERS
The ATF Open Letter changes certain federal enforcement policies. It does not repeal Delaware laws prohibiting silencers, sawed-off shotguns, or firearms classified as prohibited assault weapons under state law.
The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) has announced a significant change in how it will enforce federal National Firearms Act (NFA) requirements for suppressors, short-barreled rifles, short-barreled shotguns, and certain other firearms. But what does this mean for gun owners in Delaware?
The answer is more complicated than the headlines suggest.
Although the federal government is changing its enforcement policy, Delaware maintains separate firearms restrictions that remain in effect. Before purchasing, manufacturing, modifying, or possessing an NFA-regulated firearm, Delaware residents need to understand the distinction between federal and state law.
What Did ATF Announce?
On October 9, 2026, ATF issued an official Open Letter to federal firearms licensees and the public addressing changes to the enforcement of certain National Firearms Act provisions.
Under the new policy, ATF will no longer enforce certain federal registration, prior-approval, and tax-stamp requirements involving four categories:
- Short-Barreled Rifles (SBRs): Rifles with barrels shorter than 16 inches or weapons made from rifles that meet applicable federal NFA dimensional definitions.
- Short-Barreled Shotguns (SBSs): Shotguns with barrels shorter than 18 inches or weapons made from shotguns that meet the federal NFA definitions.
- Suppressors (Silencers): Devices designed to reduce the sound of a firearm’s discharge.
- Any Other Weapons (AOWs): A specialized federal classification that includes certain concealable firearms that are not conventional pistols or revolvers.
The announcement follows a federal court decision involving the constitutionality of certain NFA requirements after Congress reduced the making and transfer taxes on these items to zero.
The Department of Justice elected to extend its nonenforcement policy beyond the parties covered by that court order.
Federal enforcement versus federal law: ATF is announcing that it will not enforce specified requirements. Congress has not repealed the NFA, and the announcement does not eliminate state firearms laws.
Why Is This Happening?
For decades, the National Firearms Act regulated certain firearms through a federal system involving tax payments, registration, and government approval.
In 2025, Congress passed legislation reducing the federal making and transfer taxes for suppressors, short-barreled rifles, short-barreled shotguns, and AOWs to $0.
On August 5, 2026, the U.S. District Court for the Northern District of Texas issued a decision in Silencer Shop Foundation v. ATF addressing the constitutional basis for specified NFA requirements after the tax reduction.
The court’s injunction applied to specified parties rather than automatically invalidating the NFA nationwide.
The Department of Justice subsequently adopted a nationwide nonenforcement policy for certain NFA requirements, effective October 9, 2026.
The policy does not extend to every firearm regulated by the NFA. Machine guns and federally classified destructive devices remain subject to the existing NFA regulatory framework and applicable taxes.
What Does This Mean for Delaware Gun Owners?
A firearm that is no longer subject to certain federal enforcement requirements is not necessarily legal to possess in Delaware.
Delaware has its own firearms statutes, including laws prohibiting certain weapons and restricting firearms classified as assault weapons.
Let’s examine the major NFA categories individually.
1. Suppressors: Still Generally Prohibited in Delaware
One of the most discussed aspects of the ATF announcement concerns firearm suppressors, sometimes called silencers.
Suppressors are lawful for eligible civilian ownership in many states, subject to applicable laws. Delaware, however, maintains a separate statutory prohibition.
Under 11 Del. C. § 1444, Delaware identifies firearm silencers as prohibited destructive weapons.
The statute generally criminalizes making, selling, transferring, purchasing, receiving, or possessing a firearm silencer, subject to narrowly defined exceptions.
Violations involving firearm silencers are classified as a Class E felony.
What this means: The new ATF announcement does not authorize ordinary Delaware residents to purchase or possess firearm suppressors.
Even if federal registration and tax-stamp enforcement requirements are relaxed, Delaware’s separate prohibition remains in effect.
A suppressor purchased legally in another state does not automatically become lawful when brought into Delaware.
2. Short-Barreled Rifles: A More Complicated Legal Question
Short-barreled rifles deserve particular attention because Delaware law treats them differently from suppressors and short-barreled shotguns.
Delaware’s destructive-weapon statute, § 1444, does not expressly list short-barreled rifles among its prohibited weapons.
That does not mean every SBR is legal.
Delaware also regulates firearms through its assault-weapon statutes, particularly 11 Del. C. §§ 1465–1467.
Under § 1465, a semiautomatic centerfire rifle with an overall length of less than 30 inches falls within Delaware’s definition of a copycat weapon.
Other features, including certain detachable-magazine and stock configurations, can also affect classification. Named firearms and copies may be restricted independently of those features.
Consequently, a short-barreled rifle that is permissible under the new federal enforcement policy may still qualify as a prohibited assault weapon in Delaware.
A manually operated rifle or differently configured firearm may require a different legal analysis.
What this means: Delaware residents should not assume that shortening a rifle barrel, assembling an SBR, or buying a factory-built SBR is automatically lawful.
The rifle’s operating system, overall length, features, model, and applicable statutory exceptions all matter.
Anyone considering an SBR should obtain a reliable, configuration-specific legal determination before proceeding.
3. Short-Barreled Shotguns: Delaware’s Prohibition Remains
Delaware law expressly restricts sawed-off shotguns.
Under § 1444, the definition generally includes:
- A shotgun having one or more barrels shorter than 18 inches.
- A weapon made from a shotgun that has an overall length shorter than 26 inches.
The statute provides narrow exceptions but does not create a general civilian exemption simply because a firearm is federally registered or qualifies under ATF’s new policy.
What this means: Delaware residents should not interpret the ATF announcement as authorization to manufacture, purchase, or possess a prohibited short-barreled shotgun.
Certain firearms marketed as compact or pistol-grip firearms may present additional classification questions. A product’s marketing name does not determine its legal status.
4. Any Other Weapons (AOWs): Classification Matters
The NFA’s AOW category includes certain unusual or concealable firearm configurations.
Because this is a federal classification, it does not directly establish whether a particular item is lawful under Delaware law.
An AOW might also meet Delaware’s definition of a prohibited weapon or fall within another state restriction, depending on its design and features.
What this means: Delaware residents must evaluate the specific firearm, not simply rely on its federal AOW classification.
Does This Mean Gun Owners No Longer Need ATF Tax Stamps?
Under ATF’s October 9 guidance, the agency will not enforce specified NFA tax-stamp, registration, and prior-approval requirements for the four covered categories.
ATF also states that individuals may continue to submit voluntary NFA registration applications.
However, several important issues remain:
- The firearms are still subject to applicable provisions of the federal Gun Control Act.
- Federal firearms dealers remain responsible for required background checks, transaction records, and compliance with state law.
- The nonenforcement policy could change in the future.
ATF specifically acknowledges the possibility that Congress, the courts, or a future Department of Justice policy could alter the current legal situation.
An individual who acquires an unregistered NFA firearm today should not assume that the firearm will automatically be grandfathered if federal enforcement resumes.
This is an especially important consideration for anyone contemplating an irreversible firearm modification.
What About Traveling Outside Delaware?
Traveling between states introduces another layer of complexity.
ATF says it will not enforce a specified NFA restriction on interstate transportation of unregistered covered items.
However, federal Gun Control Act transportation requirements remain applicable. ATF specifically states that interstate transportation of short-barreled rifles and short-barreled shotguns continues to require Form 20 authorization.
State laws also remain in effect.
For example, possession of a suppressor may be lawful under another state’s laws but prohibited in Delaware.
Travelers must consider the laws of every jurisdiction where they will possess the firearm, including their destination.
The ATF announcement is not a nationwide permit to transport otherwise prohibited firearms.
What About Firearms Already Registered Under the NFA?
ATF states that it will continue maintaining the National Firearms Registration and Transfer Record and accepting voluntary registration applications for covered firearms.
Gun owners who already possess lawfully registered NFA firearms should exercise particular caution before requesting removal of an item from the registry.
According to ATF’s published guidance, an item removed from registration generally cannot later be re-registered unless a federal amnesty is declared.
Moreover, federal enforcement policy could change.
Existing owners should consider the consequences carefully before altering a firearm’s registration status.
Frequently Asked Questions for Delaware Residents
Can I now buy a suppressor in Delaware without a tax stamp?
No. Delaware independently prohibits firearm silencers for ordinary civilian possession under 11 Del. C. § 1444. The new federal guidance does not remove that prohibition.
Can I buy a short-barreled rifle without submitting an ATF Form 4?
ATF has announced that it will not enforce specified federal prior-approval requirements for covered SBR transfers. However, Delaware’s assault-weapon restrictions and other state and federal requirements still apply. Whether a particular SBR may legally be transferred depends on its classification and the circumstances.
Can I shorten the barrel on a rifle I already own?
Do not assume that the ATF policy authorizes the modification under Delaware law. A modification can change a firearm’s legal classification, potentially creating a prohibited assault weapon or another restricted firearm.
Are machine guns now legal without federal registration?
No. The new federal nonenforcement policy does not cover machine guns. Existing federal NFA requirements continue, and Delaware independently prohibits machine guns except under narrow statutory exceptions.
Does the ATF letter override Delaware gun laws?
No. ATF expressly confirms that the guidance does not supersede state or local firearms restrictions.
Could these federal rules change again?
Yes. ATF describes the new approach as an exercise of enforcement discretion. Later litigation, legislation, or a change in federal policy could alter it.
The Bottom Line for Delaware Gun Owners
The October 9, 2026 ATF Open Letter represents a major development in federal firearms regulation.
For owners and prospective buyers in Delaware, however, the practical impact is more limited than headlines may suggest.
Suppressors and sawed-off shotguns remain generally prohibited under Delaware law. Machine guns remain heavily restricted under both federal and state law.
Short-barreled rifles and certain AOW firearms require a more detailed examination because Delaware legality depends on the specific firearm and its configuration.
THE KEY TAKEAWAY
A change in federal enforcement does not automatically change Delaware law.
Delaware gun owners should review both federal and state requirements before making purchases, completing transfers, or modifying firearms.
