The ATF’s latest regulatory blitz has finally hit its public-comment deadline, and the Second Amendment Foundation isn’t waiting around to see what the agency does next. Kostas Moros, speaking for SAF, made it clear that the organization isn’t simply opposing every proposal; it’s offering targeted fixes that would keep the rules from becoming outright bans on common firearms and accessories. By zeroing in on the most dangerous language—definitions that could sweep in millions of lawfully owned pistols, bracing devices, and even some shotguns—SAF is trying to force the agency to color inside the lines Congress actually drew rather than letting regulators rewrite statutes on the fly. What makes this moment different is the sheer volume of simultaneous rulemakings. Instead of the usual one-off pistol-brace notice, the ATF dropped a constellation of overlapping proposals that, taken together, could redefine entire categories of firearms overnight. Moros highlighted how seemingly minor wording changes—such as broadening the definition of “rifle” or tightening the criteria for what counts as a “pistol”—create a domino effect: once a gun is reclassified, every magazine, stock, and accessory attached to it risks becoming an unregistered short-barreled rifle. That’s not a hypothetical slippery slope; it’s the same interpretive sleight-of-hand the agency used to turn millions of arm-brace owners into potential felons with the stroke of a pen. For the broader 2A community, the takeaway is that litigation and legislation must now run on parallel tracks. Even if SAF persuades the ATF to walk back the worst language, the underlying statutory ambiguity remains, giving the next administration another bite at the apple. The real win will come when Congress steps in with language that actually constrains the agency’s interpretive creativity—something the Supreme Court’s recent emphasis on textualism makes more plausible than ever. Until then, every new rule package is a reminder that rights not defended in the Federal Register are rights that can be regulated out of existence before most gun owners even realize the comment period closed.
