Nearly a century after the National Firearms Act became law, a coalition of some of the most influential Second Amendment organizations in the country is asking a federal court to strike down key portions of the legislation.

The lawsuit, Brown v. ATF, was recently filed in the U.S. District Court for the Eastern District of Missouri by the National Rifle Association (NRA), American Suppressor Association (ASA), Second Amendment Foundation (SAF), Firearms Policy Coalition (FPC), Prime Protection STL Tactical Boutique, and individual members of those organizations.

At the center of the challenge is a simple question: if Congress has eliminated the tax that originally justified the National Firearms Act, can the federal government still maintain the registration system built around that tax?

This article breaks down the lawsuit, the legal arguments behind it, and why many gun rights advocates view it as one of the most significant Second Amendment cases in years.

A Law That Dates Back to 1934

The National Firearms Act (NFA) was enacted in 1934 and imposed a $200 tax on certain categories of firearms and accessories.

The law applies to items such as:

• Suppressors (silencers)
• Short-barreled rifles (SBRs)
• Short-barreled shotguns (SBSs)
• Certain firearms classified as "Any Other Weapons" (AOWs)

In addition to the tax, owners of NFA-regulated items have historically been required to undergo federal registration and approval processes before taking possession.

For decades, supporters of the NFA argued that the law was constitutional because it functioned as a tax measure rather than a direct firearm prohibition.

What Changed?

The legal landscape shifted when President Trump signed the One Big Beautiful Bill Act (OBBB).

Among its firearm-related provisions, the legislation eliminated the long-standing NFA excise tax on suppressors, short-barreled rifles, short-barreled shotguns, and AOWs.

According to the plaintiffs, that change removed the very foundation upon which the NFA was originally justified.

Their argument is straightforward:

If the tax no longer exists, the registration system designed to enforce that tax no longer serves a constitutional purpose.

As a result, the lawsuit argues that the federal government lacks the constitutional authority to continue requiring registration of these items.

The Second Amendment Argument

The challenge goes beyond taxation.

The lawsuit also argues that NFA registration requirements violate the Second Amendment itself.

Following the Supreme Court's decision in New York State Rifle & Pistol Association v. Bruen, firearm regulations must be consistent with the nation's historical tradition of firearm regulation.

The plaintiffs contend that no historical tradition exists that would justify federal registration requirements for commonly owned arms such as suppressors and short-barreled rifles.

Supporters of the lawsuit note that suppressors are legally owned by millions of Americans and are commonly used for hearing protection, hunting, recreational shooting, and other lawful purposes.

Likewise, short-barreled rifles remain among the most popular firearm configurations registered under the NFA.

A Coalition of Major Second Amendment Organizations

The lawsuit brings together several prominent organizations that have been active in constitutional firearms litigation.

Among them are:

• National Rifle Association
• American Suppressor Association
• Second Amendment Foundation
• Firearms Policy Coalition

Leaders from each organization argue that the NFA has imposed unnecessary burdens on law-abiding gun owners for generations.

Their position is that the removal of the NFA tax creates an opportunity for courts to revisit whether the registration scheme can continue to exist at all.

Why This Case Could Be Significant

If successful, the lawsuit could have far-reaching implications for federal firearm regulation.

A favorable ruling could potentially:

• Eliminate federal registration requirements for suppressors and certain short-barreled firearms
• Further define the limits of Congress's authority under the Constitution
• Expand the application of the Supreme Court's Bruen framework
• Influence future challenges to other federal firearm regulations

While the case is still in its early stages, it reflects a broader trend of firearm laws facing increased constitutional scrutiny in the wake of recent Supreme Court decisions.

Many of the restrictions that survived for decades under older legal standards are now being reevaluated through the lens of text, history, and tradition.

Final Thoughts

For nearly ninety years, the National Firearms Act has shaped how Americans purchase, transfer, and possess certain firearms and accessories. What began as a tax-and-registration system during the Great Depression has remained largely intact despite dramatic changes in both firearms technology and constitutional jurisprudence.

Now, with the NFA tax largely removed, opponents argue that the registration requirements have been left standing without a constitutional foundation.

Whether the courts ultimately agree remains to be seen, but Brown v. ATF has the potential to become one of the most closely watched Second Amendment cases in the country.

For many firearm owners, the lawsuit represents more than a challenge to a single law—it reflects the broader effort to ensure that firearm regulations remain consistent with both constitutional limits and the rights protected by the Second Amendment.
