The Firearms Policy Coalition’s latest filing in the ongoing short-barreled rifle litigation isn’t just another procedural brief—it’s a direct challenge to the notion that the Second Amendment only protects the firearms bureaucrats happen to like. By grounding its argument in the historical tradition of compact, concealable long guns that were common at the Founding, FPC forces courts to confront the uncomfortable fact that the National Firearms Act’s registration-and-tax regime was never about “unusual and dangerous” weapons; it was about control. The brief’s strength lies in its refusal to accept the government’s post-hoc rationalizations; instead, it demands that any restriction on these arms meet the same rigorous historical test the Supreme Court laid out in Bruen, a test the 1934 Act was never designed to survive.

For the broader 2A community, this case is a pressure test of how far lower courts will stretch to preserve the NFA’s century-old architecture after Bruen. If judges treat short-barreled rifles as presumptively protected and require the government to produce actual Founding-era analogues rather than modern policy preferences, the entire regulatory house of cards built on arbitrary barrel-length distinctions begins to wobble. That outcome would not only restore practical access to compact defensive rifles for millions of Americans; it would also signal that the post-Bruen era is no longer theoretical—courts are finally being forced to dismantle the very categories of arms the administrative state has spent decades demonizing.
