What a forced reset trigger does

A forced reset trigger (FRT) is an aftermarket trigger assembly for AR-15 rifles that uses a spring-loaded hammer to reset itself after each shot without requiring the shooter to release the trigger. Instead of the standard mechanical reset that happens when you let the trigger go forward, an FRT resets while your finger is still pulling the trigger, allowing for faster follow-up shots with a single continuous trigger pull.

The mechanism works by storing energy in a spring during the firing cycle. After the hammer strikes the firing pin and the round fires, that spring pushes the hammer back into position to strike again. Because the reset happens independently of trigger finger movement, a shooter can maintain pressure on the trigger and fire multiple rounds in rapid succession — sometimes approaching the rate of a fully automatic weapon.

This design is distinct from a standard AR-15 trigger, where the hammer must physically reset before the trigger can fire again, and that reset requires the trigger to move forward (which happens when you release finger pressure). With an FRT, the trigger never needs to move forward to reset, which is the core difference that has made these devices controversial from a legal and regulatory standpoint.

Key Takeaways

  • Forced reset triggers use a spring mechanism to reset the hammer while the trigger is still being pulled, enabling rapid fire without releasing the trigger.
  • The ATF has issued guidance stating that certain FRT designs may convert a rifle into a machine gun under federal law, making possession illegal without proper registration.
  • Legal status varies depending on the specific FRT model, how it functions, and your state's firearms laws — some states have banned them outright regardless of federal status.
  • If you own an FRT, you should research the current legal status of your specific model and consult local firearms law before using or possessing it.
  • Manufacturers have modified FRT designs in response to ATF guidance, so older and newer versions may have different legal classifications.

Federal law and the ATF position on forced reset triggers

Under federal law, a machine gun is defined as any firearm that fires more than one round per trigger pull, or any firearm that can be converted to do so. The National Firearms Act (NFA) and the Firearm Owners Protection Act (FOPA) regulate machine guns strictly — civilian ownership of machine guns manufactured after 1986 is prohibited, and pre-1986 machine guns require federal registration, a tax stamp, and extensive background checks.

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) has issued multiple letters and guidance documents regarding forced reset triggers. In 2021 and 2022, the ATF determined that certain FRT models — particularly the Forced Reset Trigger (FRT-15) manufactured by Rare Breed Triggers — function in a way that converts an AR-15 into a machine gun because they fire multiple rounds per single trigger pull. The ATF's position is that the continuous spring-driven reset constitutes automatic fire under the legal definition.

However, the ATF's stance has been challenged in court, and the legal landscape remains unsettled. Some FRT manufacturers have modified their designs in response to ATF guidance, arguing that their newer versions do not meet the machine gun definition because they require a separate trigger pull for each round. The distinction hinges on technical details about how the trigger resets and whether that reset is truly independent of trigger finger movement.

State-level restrictions and bans

Beyond federal law, many states have enacted their own restrictions on forced reset triggers. Some states have explicitly banned FRTs by name or by functional description, treating them as prohibited devices regardless of the federal legal debate. States like California, New York, and others with stricter firearms regulations have moved to prohibit FRTs outright through legislation or regulatory action.

Other states have not specifically addressed FRTs but may have laws that prohibit devices designed to increase the rate of fire or convert semi-automatic weapons to automatic function. If you live in a state with strict firearms laws, an FRT may be prohibited even if the federal legal question remains unresolved.

The safest approach is to check your state's current firearms laws and any recent regulatory guidance from your state's attorney general or firearms regulatory body. State law can be more restrictive than federal law, and violating state firearms law can result in criminal charges, confiscation of the device, and loss of firearms rights.

How FRT designs have changed in response to legal pressure

After the ATF's 2021 information that certain FRTs converted rifles to machine guns, manufacturers began releasing modified versions designed to comply with the ATF's interpretation. These newer designs attempt to may support that the trigger must be released and pulled again for each shot, rather than allowing continuous fire with a single trigger pull.

The technical modifications vary by manufacturer. Some designs use different spring tensions or hammer geometry to prevent reset while the trigger is still depressed. Others have altered the relationship between trigger movement and hammer reset to create a more traditional reset cycle that requires trigger finger release.

The problem for consumers is that the legal status of these modified designs remains uncertain. The ATF has not issued blanket approval of any particular newer design, and courts have not yet definitively ruled on whether the modifications actually solve the machine gun problem or merely create a gray area. If you own an older FRT model, it may be classified differently than a newer version from the same or different manufacturer.

Practical implications for AR-15 owners

If you currently own a forced reset trigger, the practical reality is that you face legal risk depending on your location and the specific model you own. Possession of a device the ATF classifies as converting your rifle to a machine gun is a federal felony, punishable by up to 10 years in prison and substantial fines. State charges can carry additional penalties.

The ATF has not conducted widespread enforcement against individual FRT owners, but that does not mean the legal risk has disappeared. Enforcement could increase, and any interaction with law enforcement involving a rifle with an FRT could result in charges. Additionally, if you use an FRT at a range or in any public context, you expose yourself to potential reporting and investigation.

Many FRT owners have chosen to remove the devices from their rifles or sell them. If you decide to remove an FRT, straightforward replacing it with a standard trigger assembly resolves the legal issue. If you sell an FRT, be aware that selling a device you know or suspect is illegal in your state or under federal law can itself be a crime.

Understanding the technical debate around trigger resets

The legal dispute over FRTs centers on a technical question: does the trigger need to move forward for the firearm to reset, or can the reset happen independently? The ATF's position is that if the reset happens while the trigger is still depressed and the shooter can fire again without releasing the trigger, it constitutes automatic fire.

Manufacturers and some legal experts argue that if the shooter must perform a separate physical action — even if that action is a continued pull rather than a release — then each round represents a separate trigger pull. This interpretation would mean the firearm is not automatic under the legal definition.

The courts have not yet settled this debate definitively. A federal judge in Texas temporarily blocked the ATF's enforcement of its FRT information in 2023, but that ruling was narrow and did not resolve the broader question. Until a higher court issues a definitive ruling or Congress clarifies the law, the legal status of FRTs remains contested.

Alternatives to forced reset triggers for faster shooting

If you want to improve your AR-15's performance or shooting speed without the legal risk of an FRT, several legal alternatives exist. A match-grade trigger with a short, crisp break can improve accuracy and allow faster follow-up shots by reducing the time between trigger pulls. These are standard aftermarket triggers that do not alter the basic reset mechanism.

Improving your shooting technique through practice is another approach. Better trigger control, sight picture management, and muscle memory allow faster, more accurate shooting without any mechanical modification. Many competitive shooters achieve very fast rates of fire with standard triggers through skill alone.

If you are interested in automatic fire, the legal path is to purchase a pre-1986 registered machine gun (where legal), which requires ATF registration, a $200 tax stamp, and a thorough background check. This is expensive and time-consuming, but it is the only legal way to own an automatic firearm in most of the United States.

Frequently Asked Questions

Is it legal to own a forced reset trigger right now?

The answer depends on your state and the specific FRT model. The ATF has determined that certain models convert rifles to machine guns, making them illegal under federal law. Many states have also banned FRTs outright. You should research your state's current laws and consult a firearms attorney before purchasing or possessing an FRT.

What happens if I get caught with an FRT?

Possession of a device the ATF classifies as converting your rifle to a machine gun is a federal felony punishable by up to 10 years in prison and fines. State charges may explore as well. The ATF has not conducted widespread enforcement against individual owners, but that does not eliminate the legal risk.

Can I legally remove an FRT and replace it with a standard trigger?

Yes. Removing an FRT and installing a standard trigger assembly makes your rifle legal under federal law (though state laws may still restrict other aspects of your rifle). straightforward possessing an FRT, even if not installed, may be illegal depending on your state and the ATF's current enforcement posture.

Are newer FRT designs legal?

Manufacturers have released modified FRT designs intended to comply with the ATF's interpretation, but the legal status of these newer versions remains uncertain. The ATF has not issued blanket approval of any particular design, and courts have not ruled definitively on whether the modifications resolve the machine gun issue.

What is the difference between a forced reset trigger and a bump stock?

A bump stock uses recoil to move the rifle forward and backward, allowing the shooter's stationary finger to strike the trigger repeatedly. An FRT uses a spring mechanism to reset the hammer independently of trigger finger movement. Both have been targeted by regulators, but they work through different mechanical principles.
