Even with Donald Trump back in the White House and whispers from the Department of Justice about tweaking the controversial frame and receiver rule, the Second Amendment Foundation (SAF) isn’t hitting pause on its courtroom crusade. SAF’s lawsuit, *Mock v. Garland*, challenges the ATF’s 2022 redefinition of what constitutes a firearm under federal law—expanding it to include unfinished frames, receivers, and even polymer 80% lowers that hobbyists have long built into functional guns without a license. While the DOJ under Biden aggressively defended this power grab as a crackdown on ghost guns, recent filings hint at a potential rollback now that Trump’s team is at the helm. But SAF, ever the vigilant watchdog, is pressing ahead with oral arguments slated for February 2025 in federal court, refusing to let bureaucratic foot-dragging erode gun owners’ rights.

This isn’t just legal theater; it’s a high-stakes pivot point for the entire 2A landscape. The frame and receiver rule was the ATF’s end-run around Congress, unilaterally criminalizing millions of law-abiding builders overnight and fueling a black market for parts that were perfectly legal just yesterday. Trump’s inaction so far—despite campaign promises to dismantle Biden-era regs—mirrors the inertia that plagued his first term, where ATF nominations like David Chipman fizzled but deeper reforms stalled. SAF’s dogged persistence fills that void, potentially forcing a judicial smackdown that could dismantle not only this rule but set precedents against future agency overreach. Imagine: a win here restores DIY gunsmithing as a cornerstone of American ingenuity, shielding AR-15 lowers and 1911 frames from FFL scrutiny.

For the 2A community, the implications are electric—stay vigilant, because executive hints mean squat without court-enforced accountability. SAF’s battle underscores why outfits like them are indispensable: they’re the tip of the spear when politicians pivot to optics over action. Gun owners should rally behind this fight, stock up on braces and lowers while you can, and keep the pressure on. If Trump wants to claim the W, he’ll need to back SAF’s play before judges do it for him. Victory here isn’t just about parts; it’s reclaiming the Second Amendment from the administrative state.
