Forced Reset Triggers Explained: How They Work and Are They Legal?

Short answer (checked 11 October 2026): a forced reset trigger (FRT) is a semi-automatic AR-15 trigger that mechanically pushes the trigger forward after each shot, so you can fire quickly while keeping rearward pressure on it. Under current federal law it is not a machinegun: the Supreme Court's 2024 Cargill decision and a July 2024 Texas federal ruling led the Department of Justice to settle with Rare Breed Triggers on May 16, 2025. It is still banned in some states, the legal reasoning can be revisited, and real machinegun conversion devices (auto sears, "switches") remain illegal federal machineguns.

What is a forced reset trigger?

In an ordinary semi-automatic trigger you pull, the gun fires once, and you let the trigger come forward before pulling again. A forced reset trigger uses the energy of the gun cycling to push the trigger forward for you, so a shooter who keeps pressing rearward fires again as soon as it resets. Whether each shot takes its own function of the trigger is the question the courts applied. It is not a binary trigger, which fires on the pull and again on the release (see our best AR-15 triggers and trigger comparison).

Why is a forced reset trigger not a machinegun?

The federal definition (26 U.S.C. 5845(b)) covers a weapon that shoots, or can be readily restored to shoot, "automatically more than one shot, without manual reloading, by a single function of the trigger," plus parts designed and intended solely and exclusively to convert a weapon into one. In Garland v. Cargill (June 14, 2024, 6-3) the Supreme Court held that a bump stock cannot fire more than one shot "by a single function of the trigger," so ATF exceeded its authority by classifying bump stocks as machineguns. A month later the Northern District of Texas applied that reasoning to forced reset triggers and concluded they cannot be classified as machineguns either. The Justice Department then settled instead of continuing its appeals.

The federal timeline

Timeline of federal actions on forced reset triggers: Cargill in June 2024, the Texas ruling in July 2024, the DOJ settlement in May 2025, sixteen states suing in June 2025 and dropping the suit in April 2026, and ATF's October 2026 NFA letter

What still matters before you buy

  • State law. Several states ban or restrict forced reset triggers, binary triggers or "trigger activators". A federal ruling does not override a state ban. Check your state and any city rules.
  • Machinegun conversion devices are different. An auto sear, "switch" or other part that makes a rifle fire automatically is a machinegun under the NFA, and possessing or transferring one is a federal crime. The ruling and settlement concern forced reset triggers, not those parts.
  • The settlement is about Rare Breed's products. The Texas ruling and DOJ release name Rare Breed's devices; another maker's design is not named in them.
  • It can change. A court ruling and a settlement are not a statute. Future courts, future administrations or Congress can revisit the question, and ATF's 2026 policy shifts show how quickly guidance moves. Keep your purchase records.
  • Prohibited persons may not possess firearms.

Forced reset triggers and selectors we track

Two kinds of product use the forced reset idea. A drop-in forced reset trigger replaces the trigger group. A forced reset selector (or "forced reset safety") replaces the safety selector and works with a standard trigger group; AS Designs (ARC-Fire) and Atrius Development make them, and Atrius calls its selector an alternative to a forced reset trigger. The 2024 ruling and the 2025 settlement name Rare Breed's devices; the products below are other makers' designs, so read the state-law and federal notes above first. Prices from OpticsPlanet today:

Frequently asked questions

What is a forced reset trigger?

A semi-automatic AR-15 trigger that uses the gun's cycling to push the trigger forward after each shot, so it resets without you releasing it.

Are forced reset triggers legal?

Federally, yes: in July 2024 a Texas federal court held they cannot be classified as machineguns, and the Justice Department settled with Rare Breed Triggers on May 16, 2025. Some states ban them, so check yours.

Is a forced reset trigger a machinegun?

Not under current federal law. The Supreme Court held in Cargill that firing more than one shot requires more than one function of the trigger, and the Texas court applied that to FRTs. Auto sears and "switches" are machineguns.

What did the Rare Breed settlement do?

It resolved the government's lawsuits and appeals over Rare Breed's triggers. Rare Breed agreed not to design FRTs for pistols and to enforce its patents.

How is an FRT different from a binary trigger?

A binary trigger fires once when you pull and again when you release. An FRT resets the trigger for you so you can fire again by keeping pressure on it.

Could the law change?

Yes. A court ruling and a settlement are not a statute, and states set their own rules.

Where can I buy a forced reset trigger?

From firearm parts retailers. We list drop-in forced reset triggers and forced reset selectors from OpticsPlanet with today's prices. Check your state's law first, because some states ban them and a retailer may not ship there.
