The bottom line
Senator Chris Murphy introduced Senate Amendment 2973 to H.R. 3944, proposing to raise the NFA tax on suppressors, short-barreled rifles, short-barreled shotguns, and any other weapons to $4,709. This came less than three weeks after the One Big Beautiful Bill took effect and zeroed out that same tax entirely. The amendment has no path to passage. It is not designed to pass. It is designed to send a message, and the message is that the moment gun owners gain ground, Democrats will legislate to take it back.

What Congress just gave us and what Murphy wants to do about it
The One Big Beautiful Bill, signed by President Trump on July 4, 2025, eliminated the $200 NFA tax stamp on suppressors, short-barreled rifles, short-barreled shotguns, and any other weapons, effective January 1, 2026. The background check and ATF Form 4 process remain in place, but the tax itself is gone. For the first time since 1934, Americans can legally acquire a suppressor or an SBR without paying a federal tax for the privilege of exercising a constitutional right.
Eighteen days into that new reality, Senator Chris Murphy introduced S.Amdt.2973 to H.R. 3944, the military construction and veterans affairs appropriations bill. The amendment would impose a new NFA tax of $4,709 on each NFA item transferred. For AOWs, which currently carry a $5 transfer tax that was not eliminated under the One Big Beautiful Bill, Murphy’s amendment would raise the rate to $55. The $4,709 figure is not round because there is no logic behind it. It is a number designed to be prohibitive while appearing technical.
To be clear about the legislative mechanics: this amendment has no realistic chance of becoming law. It was introduced without co-sponsors, without committee support, and it directly conflicts with a statute that was signed into law less than a month ago. Gun Owners of America flagged immediately that the amendment likely violates Senate Standing Rule XVI, which restricts appropriations riders to provisions that directly affect expenditures. Attaching a new excise tax framework to a VA and military construction spending bill is a stretch that Senate parliamentarians would likely reject. Multiple Senate allies of gun rights advocates have already committed to opposing it.
That is not the point. Murphy knows it will not pass. I know it will not pass. The question worth asking is why he introduced it anyway, and the answer to that question is more important than the amendment’s legislative prognosis.
The suppressor debate requires accepting that the original law was built on a lie
The National Firearms Act of 1934 regulated suppressors for a specific reason: legislators and law enforcement officials feared that widespread suppressor use would allow criminals to fire guns in public without bystanders hearing the shot. That was the stated rationale in the congressional record. Not noise pollution. Not hearing protection for shooters. The concern was that suppressors would enable silent crime.
I want to state plainly that this rationale was false when the law was written and remains false in 2026. A suppressor does not make a firearm silent. It reduces the sound of a gunshot from an average of 160 decibels to somewhere between 130 and 140 decibels, still well above the threshold for hearing damage and still audible from a significant distance. The suppressed gunshot is louder than a jackhammer at one meter. The Hollywood depiction of a suppressed pistol producing a near-silent click has no relationship to acoustic reality.
The countries that actually understand this have regulated suppressors accordingly. In Finland, the Czech Republic, and several other European nations, suppressors are sold over the counter with minimal restriction because they are correctly understood as hearing safety devices. In the UK, purchasing a suppressor requires a standard firearms license but no special permit beyond that. The practical result is that European shooters protect their hearing as a routine matter. The United States, for reasons rooted in a 1934 misunderstanding about criminal tactics, requires a federal tax, a registration, and a months-long waiting period for the same device.
The One Big Beautiful Bill removed the tax. The ATF form and background check remain. Someone who wants a suppressor in 2026 still has to submit paperwork and pass the same background check as a standard NFA transfer. What changed is that they no longer pay $200 for the privilege. Murphy’s amendment would replace that zero with $4,709, a sum that is specifically calibrated to make suppressor ownership financially impossible for the middle-class gun owners who are most likely to benefit from hearing protection while shooting.
Short-barreled rifles and shotguns: the logic has always been broken
The NFA’s regulation of short-barreled rifles and short-barreled shotguns is one of the genuinely incoherent structures in American firearms law, and I say that as someone who has spent a lot of time thinking through how these regulations are supposed to work.
A standard AR-15 with a 16-inch barrel is entirely unregulated beyond the normal background check process. The same lower receiver fitted with a 14.5-inch barrel is a short-barreled rifle under the NFA, subject to registration, tax, and federal approval. The firearm is functionally almost identical. The shorter barrel is marginally more maneuverable in confined spaces, which has practical home defense applications, but is not meaningfully more dangerous in any way that a standard rifle is not. A pistol with no stock and a 4-inch barrel is legal with no special requirements. Attach a brace in certain configurations, add a few inches of barrel, and you are potentially in NFA territory. The line drawn by the statute has no coherent relationship to actual dangerousness.
Short-barreled shotguns are, if anything, more defensible as a regulated category because of the genuine stopping power at close range, but the regulation still does not hold up under scrutiny. A homeowner defending against an intruder in a hallway would be well-served by an 18-inch-barreled pump shotgun, which requires no special permit. The same homeowner would be equally or perhaps better served by a 14-inch model with the same ammunition, superior maneuverability in tight quarters, and less risk of over-penetration into adjacent rooms. The 14-inch model requires an NFA stamp, months of waiting, and until January 1 of this year, a $200 tax. The 18-inch model can be bought that afternoon. There is no public safety rationale that explains this difference.
Murphy’s $4,709 tax would make a practical home defense tool financially inaccessible to the majority of Americans who might want to own one legally. That is not incidental to the proposal. It is the purpose.
Virginia already tried the same thing at the state level
This is not the first attempt to reconstruct the NFA tax barrier that Congress just removed. Virginia House Bill 207, prefiled on January 7 and formally introduced on January 14, would impose a $500 state excise tax on every retail suppressor sale in the commonwealth, effective July 1, 2026. The federal tax was zeroed out. Virginia’s response, before the calendar had even changed, was to propose a replacement state tax at two and a half times the rate.
The Virginia bill exempts purchases by law enforcement and government agencies. Private citizens buying hearing protection for recreational shooting or for their own safety would pay the $500 tax. The revenue would go into the general fund, not into any hearing safety or public health program. There is not even a pretextual public benefit framing on the bill. It is a straight revenue capture targeting one category of law-abiding gun owner.
The pattern is clear once you see it. Congress eliminates the federal NFA tax. States immediately introduce replacement taxes calibrated to replicate the financial barrier Congress just removed. Murphy introduces a federal amendment to restore the federal barrier at twenty-three times its previous level. The goal is not to regulate a specific harm. There is no documented harm from legally registered NFA items in civilian hands. The goal is to maintain cost as the mechanism for limiting who can exercise rights that the law now permits.
The honest answer to why this keeps happening
I have genuinely tried to construct a good-faith policy argument for why suppressors should carry a $4,709 federal tax. I cannot do it. Suppressor-related crime statistics from legally registered NFA items are essentially nonexistent. The American Suppressor Association has reported that suppressed firearms are used in crime at a vanishingly small rate given the existing regulatory framework. Even if you stripped out the regulatory framework entirely and allowed free suppressor sales, the evidence from countries that do exactly that is that the crime-related outcomes do not change meaningfully.
The only argument I can construct is the misinformation argument, which is that public fear of “silencers” makes the political cost of eliminating the restriction lower than it actually should be, so legislators who want to signal toughness on guns use suppressor restrictions as a proxy. That is not a policy argument. That is a calculation about which lies are electorally sustainable.
Gun Owners of America called Murphy’s amendment precisely what it is: a direct political response to a legislative loss. Senator Murphy lost the suppressor fight in the One Big Beautiful Bill. His response was to immediately propose a replacement restriction at a higher cost. The National Shooting Sports Foundation similarly noted that the amendment is a “preview” of Democratic legislative strategy going forward, which is to use any available vehicle, regardless of subject matter, to reintroduce the financial and regulatory burdens that Congress just removed.
I think that reading is exactly right. And the reason it matters is not just about suppressors or SBRs. The reason it matters is that a $200 tax that has existed since 1934 was finally eliminated, and the political response within weeks was an attempt to replace it with a $4,709 tax. That tells you everything you need to know about how one side of this debate views the Second Amendment: as a problem to be managed through cost and delay rather than a right to be respected. The amendment will fail. The next attempt will come. The only counter to it is the same thing that produced the One Big Beautiful Bill in the first place, which is sustained political engagement from people who understand what is at stake and refuse to let the issue go quiet.
