The Second Amendment Foundation and its allies have just dropped a powerful new brief in their challenge to the National Firearms Act, timed perfectly after the Supreme Court’s recent decisions that have begun to chip away at the administrative state’s ability to rewrite statutes on the fly. Rather than treating the NFA as some untouchable relic, the filing argues that the ATF’s modern expansions—especially the reclassification of pistol braces and the aggressive enforcement of “machine gun” definitions—stretch the original 1934 law far beyond what Congress ever authorized. By anchoring their arguments in the Court’s new emphasis on historical tradition and textual limits, SAF is essentially telling the judiciary: if Bruen and its progeny mean anything, they mean the government can’t just invent new restrictions and call them “clarifications.”
What makes this filing particularly sharp is how it reframes the NFA not as a settled compromise from the New Deal era, but as an increasingly brittle statute whose enforcement mechanisms now collide with both the Second Amendment and the separation of powers. The brief highlights how the ATF has turned registration requirements and tax stamps into de facto bans on entire categories of arms that were never contemplated in 1934, effectively shifting the burden onto citizens to prove their rights rather than forcing the government to justify its restrictions. For the 2A community, this isn’t just another court filing—it’s a strategic recognition that the post-Bruen landscape rewards challenges that attack the administrative overreach itself, not merely the policy outcomes.
The implications stretch well beyond braces and short-barreled rifles. If courts begin applying the same historical-tradition test to the NFA’s core provisions, the entire structure of federal gun control built on registration and taxation could face sustained pressure. This brief signals that groups like SAF are no longer content to play defense against each new ATF rule; they’re going on offense against the legal architecture that lets agencies expand their own power. For gun owners watching the slow erosion of administrative deference, this case could become the next major front in determining whether the right to keep and bear arms remains subject to 90-year-old bureaucratic gatekeeping or finally receives the full constitutional scrutiny the Supreme Court has promised.
