ATF “Frame and Receiver” Rule Back From the Dead—And Still a Problem

Home hobbist have long enjoyed the ability to build their own firearms

Just when you thought the fight over the ATF’s controversial “frame and receiver” rule was over, the Department of Justice has once again changed course. Now, instead of scrapping the Biden-era regulation, the DOJ is moving forward with a new version of the same rule. They are looking to keep the core framework intact while making limited adjustments.

Once again the Trump Administration is siding with Biden area anti-gun policies instead of keeping the promises made to gun owners. This shows the unease that gun owners have this this administration as they continue to take anti-2a stances. Heading into an election year, this could spell big issues for maintaining voter support.

A Rule That Redefined Firearms—Without Congress

At the center of this fight is ATF Final Rule 2021R-05F, which dramatically expanded what qualifies as a firearm under federal law. Instead of applying only to fully completed firearms and finished frames and receivers, the rule expanded regulation. This included a host of partially completed components, disassembled parts, and build kits.

Even included items that were dubbed “readily” converted into a firearm. That single word—“readily”—is where the real problem begins. This phrase is beyond vague and open to interpretation.  

What the Rule Requires

Under this expanded definition, individuals and businesses must obtain a Federal Firearms License (FFL). Then they have to serialize parts, conduct background checks, all while maintaining detailed records.

This effectively turns homebuilding and gunsmithing—longstanding American traditions—into heavily regulated activities. We have seen issues with the federal government stepping into home hobbies getting slapped down recently.

The Legal Rollercoaster

This issue has been bouncing through the courts for years at this point. A federal district court struck the rule down and the Fifth Circuit agreed. But the  Supreme Court reversed that decision—but narrowly. Importantly, the Supreme Court did NOT fully endorse the rule.

Instead, they left the door open for constitutional challenges and “as-applied” challenges under Bruen. The constitutional question here has yet to be answered and must be addressed here soon. Otherwise, we will continue to see changes such as this from administration to administration.

DOJ’s Flip-Flopping Raises Red Flags

Here’s where things get messy. DOJ initially requested time to rewrite the rule then said it would keep the Biden rule intact. Now it’s reversing again and issuing a new version. This is not regulatory clarity—it is confusion. This raises a serious question if the rule was lawful and sound, why does it keep changing?

What the New Rule Looks Like

According to insiders, the updated version will keep most of the original framework. It will slightly narrow what qualifies as “readily convertible”. It plans to treat different materials (like polymer vs. metal) differently. Make no mistake though. the core concept remains the same—expanding federal control over firearm components.

This isn’t just a legal debate. It affects small businesses across the country.  We have seen several small firearm manufacturers go out of business since this rule went into effect. This rule increases compliance costs. Imposes time consuming serialization requirements.

It also includes burdensome recordkeeping requirements. It will have an outsized impact on smaller shops. We are already seeing a shrinking within the firearms industry as regulations and cost continue to drive business out of the industry. No one is exempt from these pressures.

The biggest loser in all of this, however, is the hobbyists. Due uncertainty over what is legal and fear of accidental violations, you will see a decrease in this market. It has driven many who have enjoyed exercising their rights through home building of firearms out of the industry entirely.   

The firearm industry is not exempt from this either. Due to constant regulatory changes, it causes supply chain disruption which means rising costs passed on to consumers. It also makes the industry hesitant in stepping into innovation in various fields out of fear of being noncompliant. That means the innovation the firearm industry enjoys could stagnate.

The Bigger Issue: Executive Overreach

At 2 If By Sea Tactical, we are concerned about this fair beyond what constitutes a frame or receiver. This is about who has the authority to make law. Congress never passed legislation redefining firearm components this way. Instead, an administrative agency rewriting definitions. The executive branch is expanding enforcement power. They are creating new legal risks for millions of Americans outside of the founding principals.

What Comes Next

The courts are far from done with this issue. We can expect new lawsuits and injunction requests in the near future. We will see challenges under the Bruen standard as this rule violates the text, history, and tradition standard set forth by the Supreme Court.  The Supreme Court left the door open and this fight is likely heading back to the High Court.

Bottom Line

The ATF’s “frame and receiver” rule is still alive—but it’s far from settled. Despite multiple legal challenges and political pressure, the federal government is defending it. They are pushing a regulatory framework that expands definitions beyond congressional intent.

They are burdening lawful gun owners and businesses on vague standards like “readily convertible”. Until this is resolved, every gun owner, builder, and manufacturer is left navigating uncertainty. This is not created by law, but by bureaucratic interpretation created whole cloth out of then air. Stay tuned. This one isn’t over.
