Idaho Draft Bill RCB204: A Quiet Strategy in Machine Gun Law

At first glance, Idaho’s draft bill RCB204 may not seem particularly dramatic. It doesn’t declare a constitutional showdown with the federal government. It doesn’t attempt to ignore federal law. And it doesn’t rely on creative legal gymnastics to reinterpret existing statutes.

Instead, it takes a much simpler approach.

The bill essentially says that machine guns are legal under Idaho law if they are legal under federal law.

That may sound obvious, but from a legal perspective, it could matter quite a bit.

Federal Law Still Controls Machine Guns

Under current federal law, specifically the Hughes Amendment of 1986, civilians generally cannot possess newly manufactured machine guns. The amendment effectively froze the civilian machine‑gun registry, meaning only machine guns registered before May 19, 1986, remain transferable to civilians.

Because of that restriction, the number of legally transferable machine guns in the United States is fixed, which is why those firearms often sell for tens of thousands of dollars today.

Most states structure their laws to mirror that federal framework. In many cases, state statutes either directly incorporate federal restrictions or impose their own parallel prohibitions.

What RCB204 Actually Does

RCB204 takes a different, strategic approach.

Rather than adding new restrictions or attempting to find a loophole in federal law (such as a bill gaining national attention in West Virginia), the Idaho bill simply ensures that Idaho law will not be more restrictive than federal law.

In practical terms, that means:

• If federal law prohibits machine guns, Idaho law prohibits them as well.
• If federal law ever changes, whether through Congress or a court decision, Idaho law automatically allows what federal law allows.

This alignment means Idaho would not be able to restrict machine guns at the state level if federal machine gun laws are ever modified.

Avoiding a Direct Federal Conflict

Some states attempt to challenge federal gun laws directly through legislation. Those efforts often lead to immediate federal litigation, with courts stepping in to determine whether the state law conflicts with federal authority.

RCB204 avoids that confrontation entirely.

Rather than challenging federal law, Idaho is essentially saying:

“If the federal government ever changes the rules, Idaho will not stand in the way.”

This approach allows the state to remain compliant with current federal law while also positioning itself for potential changes in the future.

Quiet Legislation Can Still Be Significant

This type of legislation may not attract the same attention as more dramatic proposals, but it can still be important.

Often, the most meaningful legal developments do not come from sweeping political battles. Instead, they appear in the form of technical statutory language that quietly prepares for future legal changes.

RCB204 appears to fall into that category.

The bill does not attempt to overturn federal law. It simply ensures that if federal machine gun regulations ever change, Idaho’s own statutes will not be the obstacle preventing lawful ownership.

The Bigger Picture

One of the core themes of legal analysis, something lawyers encounter constantly, is that the law is rarely black and white.

Major changes sometimes come from dramatic court decisions. But just as often, they come from smaller legislative adjustments that position a state for whatever legal developments may come next.

In the case of RCB204, Idaho is simply preparing for the possibility that federal machine gun law could change someday.

And if it does, Idaho wants to make sure its own laws do not stand in the way.  Happy shooting.
