What a forced reset trigger does

A forced reset trigger (FRT) is an aftermarket trigger mechanism designed to reset itself automatically after each shot, without requiring the shooter to release the trigger. In a standard AR-15 trigger, the shooter must pull and then fully release the trigger between shots. With an FRT, the trigger resets while still held down, allowing the next round to fire as soon as the bolt cycles forward.

The mechanism works by using a spring-loaded hammer or sear that pushes the trigger forward into firing position after each shot. This happens mechanically during the bolt's return cycle, independent of the shooter's finger movement. The result is a higher rate of fire than a conventional semi-automatic trigger, achieved without the shooter having to manipulate the trigger finger between rounds.

FRTs became commercially available in the mid-2010s and generated when ready controversy because they blur the line between semi-automatic and fully automatic fire. A skilled shooter can fire an FRT-equipped rifle at rates approaching automatic weapons by using a bump-fire technique or straightforward holding steady pressure on the trigger.

Key Takeaways

  • A forced reset trigger resets itself during the bolt cycle, allowing rapid fire while the trigger is held down, which differs fundamentally from how standard semi-automatic triggers work.
  • The ATF has issued conflicting guidance on FRTs over time, initially ruling some legal and later reversing course to classify certain models as machine gun components.
  • As of 2024, the legal status of FRTs remains unsettled, with ongoing litigation and varying enforcement across federal jurisdictions.
  • Possession of an FRT may violate federal law depending on the specific model, your state of residence, and current ATF interpretation, which has changed multiple times.
  • If you own an FRT or are considering one, consulting a firearms attorney in your state is the only reliable way to understand your legal exposure.

How the ATF has classified forced reset triggers

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) has taken multiple positions on FRTs since they entered the market. In 2015, the ATF issued a letter stating that certain FRT designs did not convert a rifle into a machine gun under federal law, because the trigger itself did not cause multiple rounds to fire with a single function of the trigger. This letter was cited by manufacturers and sellers as legal cover for years.

In 2021, the ATF reversed this position. The agency issued a new information stating that certain FRT models—specifically naming the Forced Reset Trigger made by Rare Breed Firearms—functioned as machine gun components because they allowed multiple rounds to fire with a single pull of the trigger. The ATF argued that the automatic reset mechanism, combined with the shooter's ability to hold the trigger down, meant the weapon fired multiple rounds per trigger function.

This reversal created when ready legal conflict. Rare Breed Firearms and other manufacturers sued the ATF, arguing the agency had exceeded its authority and that the trigger still required the shooter to maintain pressure—making it fundamentally different from a machine gun. Federal courts have issued mixed rulings, and as of 2024, the legal status remains contested in different circuits.

Current legal status and ongoing litigation

No single answer applies nationwide. The legal status of FRTs depends on which federal circuit you live in, which specific trigger model you own, and which ATF guidance is currently in effect. Some circuits have temporarily blocked the ATF's ban on certain models pending full litigation. Others have allowed enforcement to proceed.

The core legal question is whether an FRT converts a semi-automatic rifle into a machine gun. Federal law defines a machine gun as a weapon that fires more than one round per single function of the trigger. The ATF argues that holding down an FRT trigger constitutes a single function that results in multiple rounds. Manufacturers argue that each round requires a separate mechanical reset, and the shooter's finger position does not constitute a "function" of the trigger in the legal sense.

Several cases are pending in federal court, and the Supreme Court has not yet ruled on the issue. Until there is a final decision, the legal landscape remains unstable. Some states have also passed their own laws banning FRTs or treating them as machine gun components, regardless of federal ATF guidance.

State-level restrictions on forced reset triggers

Beyond federal law, individual states have taken their own positions. Some states have explicitly banned FRTs through legislation or regulatory action. Others have not addressed them specifically, leaving the federal question to explore. A few states have passed laws that define any device allowing rapid fire as a machine gun component, which would capture FRTs under that definition.

California, New York, and several other states with stricter firearms regulations have moved to ban FRTs outright. Some states have done this through emergency regulations, while others have passed legislation. The specifics vary by state, and some bans explore only to possession, while others also restrict sale and transfer.

If you live in a state that has not explicitly addressed FRTs, the federal legal uncertainty still applies. State law does not override federal law, so even if your state has not banned FRTs, federal charges could still explore if the ATF's position holds up in court.

What happens if you own an FRT now

If you currently own a rifle with an FRT installed, your legal exposure depends on several factors: which specific trigger model you own, which state you live in, whether your state has banned FRTs, and whether the ATF is actively enforcing its ban in your area. The ATF has not conducted widespread raids or arrests specifically for FRT possession, but enforcement could change.

The safest course is to remove the FRT and replace it with a standard trigger. This eliminates federal legal risk and any state-level risk. If you are uncertain whether your trigger qualifies as an FRT under current law, a firearms attorney can review your specific device and give you an informed opinion based on your state and current case law.

Some owners have chosen to keep their FRTs and monitor litigation, betting that courts will ultimately rule in favor of manufacturers. This approach carries legal risk if enforcement accelerates or if courts rule against them. Others have sold their FRTs or stored them, treating the legal uncertainty as reason enough to avoid possession.

Alternatives to forced reset triggers

If you want a faster trigger response without the legal uncertainty, several alternatives exist. A standard match-grade trigger or a quality aftermarket semi-automatic trigger can improve accuracy and reduce trigger pull weight without changing the fundamental firing mechanism. These remain clearly legal and do not raise machine gun concerns.

Binary triggers, which fire on both the pull and the release of the trigger, occupy a different legal space. The ATF has generally treated binary triggers as legal, though some states have banned them. A binary trigger still requires two separate trigger functions (pull and release) to fire two rounds, which is why the ATF has been more hesitant to classify them as machine guns. However, binary triggers are also controversial and their legal status could change.

Bump stocks, which use recoil to cycle the trigger, were banned federally in 2019 after the ATF reclassified them as machine gun components. That ban has survived legal challenges, so bump stocks are no longer a legal option. The FRT controversy is partly a repeat of the bump stock debate, with manufacturers and owners arguing the device is legal while the ATF argues it functions as a machine gun.

How to research your specific trigger model

If you own an FRT or are considering buying one, start by identifying the exact model and manufacturer. Different triggers have been treated differently by the ATF. The Rare Breed Firearms FRT was specifically named in the 2021 ATF information, but other models may not have been formally addressed.

Check the ATF's website for any letters or determinations related to your specific trigger model. These letters are public record and can be found through the ATF's firearms technology branch. If your model has not been formally addressed, that does not mean it is legal—it means the ATF has not yet issued a public ruling on it.

Next, research whether your state has passed any laws or regulations addressing FRTs. Your state attorney general's office or a local firearms attorney can tell you whether your state has taken a position. Finally, consult a firearms attorney licensed in your state. They can review your specific situation, your trigger model, current case law in your circuit, and give you an informed assessment of your legal risk.

Frequently Asked Questions

Is a forced reset trigger the same as a bump stock?

No. A bump stock uses recoil to cycle the trigger back and forth, while an FRT uses a spring-loaded mechanism to reset the trigger automatically during the bolt cycle. Bump stocks were banned federally in 2019. FRTs remain legal in some jurisdictions and illegal in others, with ongoing litigation.

Can I legally own an FRT if I live in a state that has not banned them?

State law does not override federal law. Even if your state has not banned FRTs, federal law may still prohibit them if the ATF's classification holds up in court. The safest assumption is that FRTs carry legal risk in all jurisdictions until the courts issue a final ruling.

What should I do if I already bought an FRT?

The safest option is to remove it and replace it with a standard trigger. If you want to keep it, consult a firearms attorney in your state who can review your specific trigger model and current case law in your circuit. They can give you an informed opinion on your legal exposure.

Will the Supreme Court rule on forced reset triggers?

The Supreme Court has not yet taken a case on FRTs. Several cases are pending in federal courts, and a ruling could eventually reach the Supreme Court, but there is no timeline for that. Until then, the legal status remains unsettled and varies by circuit.

Are there legal triggers that fire faster than standard triggers?

Yes. Match-grade triggers and quality aftermarket semi-automatic triggers can reduce trigger pull weight and improve response time without changing the firing mechanism. Binary triggers, which fire on both pull and release, occupy a different legal space and are legal in most jurisdictions, though some states have banned them. Both options avoid the legal uncertainty surrounding FRTs.
