If you’re one of the thousands of Americans who rushed to “make” an SBR, SBS, or suppressor after the Texas federal court’s injunction against the ATF’s Rule 2021R-05, you may still be staring at a blank receiver wondering whether the old engraving rules still apply. The short answer is yes—until the Fifth Circuit or the Supreme Court says otherwise, the National Firearms Act’s marking requirements remain in force, and the injunction only paused the pistol-brace redefinition, not the underlying engraving mandates. That means your home-built NFA item still needs your name (or trust name), city and state, and a unique serial number in the same 1/16-inch minimum characters the ATF has always demanded; skip it and you risk an unserialized NFA violation even if the pistol-brace rule never takes effect. The deeper story here is how the injunction exposes the ATF’s habit of treating every new rule as an all-or-nothing package. By suspending only the reclassification of braced pistols, the court left the rest of the NFA universe untouched, reminding hobbyists that “shall not be infringed” victories are often narrow and technical. The practical takeaway is to treat the injunction as a temporary safe harbor for braced pistols, not a green light to skip compliance steps that pre-date the pistol-brace fight. Makers who already have their Form 1 approved should finish the engraving exactly as the stamp instructs; those still waiting on approval can engrave in advance, because the marking requirement is triggered by making the firearm, not by receiving the stamp. For the broader 2A community, this moment is a lesson in incrementalism: courts can blunt the ATF’s overreach, but they rarely erase the underlying statute. The real endgame remains a legislative or constitutional challenge to the NFA itself, not a patchwork of injunctions. Until that day, prudent builders will keep the dremel and punch set handy, engraving exactly as the law still requires—because the safest NFA firearm is the one that is both legally made and clearly marked.
