Binary Triggers by State: Where They Are Legal

The federal position

Binary triggers are lawful under federal law. They are not machine guns under 26 U.S.C. section 5845(b), because the ATF treats the trigger pull and the trigger release as two separate functions of the trigger. One round fires per function, which is the semi-automatic definition.

That reasoning is worth understanding because it is different from the forced reset analysis, even though both end up in the same place federally.

The states that ban them

As of our latest check, twelve states have active bans: California, Connecticut, Delaware, Hawaii, Illinois, Maryland, Massachusetts, New Jersey, New York, Oregon, Rhode Island and Washington.

Florida and the District of Columbia are described as legally unsettled, which is a category worth respecting rather than treating as permissive.

Treat that as a starting point for verification rather than a conclusion.

The list is not the same, and that matters

This is the single most important thing on this page.

The states restricting forced reset devices and the states banning binary triggers overlap heavily and are not identical. Colorado and Nevada appear on the forced reset list and not on this one. Minnesota appeared on both until recently.

Minnesota changed in 2026

Worth knowing both for itself and as an illustration of how these things move.

In May 2026 the Minnesota Court of Appeals struck down that state's binary trigger ban, holding that the legislature violated the state constitution's single-subject clause by burying the restriction inside a 2024 omnibus tax and spending bill.

Binary triggers are lawful in Minnesota as a result.

Note what that turned on: not the Second Amendment, but a procedural defect in how the law was passed. That is a reminder that these outcomes often hinge on technical grounds nobody was arguing about publicly, and that they can reverse if a legislature simply passes the same restriction properly.

Why the wording matters again

As with forced reset devices, state statutes rarely say "binary trigger." They tend to prohibit devices that increase the rate of fire, sometimes phrased as trigger activators or multiburst trigger activators.

Search your state code for that language rather than the product name. A statute that never mentions binary triggers can still prohibit them comfortably.

Where wording is broad, the scope can be genuinely ambiguous, which is a good reason to get advice rather than reason from the device category yourself.

What this means practically

In a permissive state, the practical questions are the ones our binary trigger guide covers: selector behaviour, platform fit, and the release-shot discipline that people underestimate.

In a banned state, do not buy one, and do not travel with one into that state. There is generally no grandfathering for someone relocating with prohibited hardware.

In Florida or DC, where status is described as unsettled, treat that as a reason for legal advice rather than an opportunity.

Buying across a state line

The most common practical question is whether you can buy one in a permissive state and bring it home, and the answer is no.

The relevant law is the law where the device ends up, not where the transaction happened. Buying lawfully in one state and transporting into a state that prohibits the device is an offence in the destination state, and the purchase being lawful where it occurred is not a defence.

The same applies to online ordering. A retailer shipping to you is generally checking their own obligations, and some are better than others at screening destinations. Do not treat a completed order as confirmation that the device is lawful where you live.

This also catches people driving through. If your route passes through a restricting state, that transit has its own rules, and they are not always the same as the rules for residents.

If you want the capability and your state says no

There is no clean workaround, and you should be suspicious of anyone offering one.

What there is, in most restricted states, is the ordinary route: a good single-stage or two-stage trigger, a rifle that is set up properly, and practice. A competent shooter with a conventional trigger shoots faster than most people expect, and it is legal everywhere.

What we would do

Check the specific category, in your specific state, using trigger activator wording rather than the product name. If you find a provision, stop. If you do not, it is still worth a short conversation with an attorney before spending money in a category this politically active.

And check again if you move. That is where people get caught.
