Are Forced Reset Triggers Legal in Idaho? 2026

Are Forced Reset Triggers Legal in Idaho?

No. Forced reset triggers (FRTs) are considered machine guns under federal law per a Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) ruling. While Idaho has no specific state law banning FRTs, federal law applies within the state, making possession a potential felony. Ownership is illegal without NFA registration.

The Federal Stance vs. Idaho's Gun Culture

The question of forced reset trigger legality in Idaho isn't straightforward. On one hand, you have the federal government's clear classification. In 2022, the ATF issued an open letter stating that triggers marketed as FRTs are, in fact, machine guns as defined by the National Firearms Act (NFA) and Gun Control Act (GCA). This isn't a new law passed by Congress; it's the ATF's interpretation of existing statutes. This single ruling effectively made possession of these devices a federal crime overnight for individuals who didn't have them properly registered as machine guns, which was impossible for newly manufactured items.

On the other hand, you have Idaho. The Gem State has a well-earned reputation for its robust Second Amendment protections and a general legislative skepticism toward federal overreach in firearms regulation. Idaho has no state-level law that specifically names or bans forced reset triggers. This creates a confusing and high-stakes environment for gun owners. While state and local police might not be focused on FRT possession, federal agencies like the ATF operate within Idaho and can and do enforce federal law. The situation is complicated, similar to the legal questions gun owners face regarding forced reset trigger legality in Colorado, though the political climate in Idaho is vastly different.

This article will dissect the federal rule, examine Idaho's specific statutes, explain the mechanics of how these triggers work, and outline the very real legal risks Idahoans face by possessing an FRT.

ATF's Reclassification: The 'Single Function' Doctrine

To understand the federal ban, you have to look at the precise wording of the law. The NFA defines a machine gun as any weapon which shoots, is designed to shoot, or can be readily restored to shoot, automatically more than one shot, without manual reloading, by a single function of the trigger. For decades, this was understood to mean a continuous stream of fire as long as the trigger was held down. Devices like bump stocks and FRTs challenged that interpretation.

The ATF's argument is that an FRT-equipped firearm fires more than one shot with a single, continuous, and rearward pull of the trigger by the shooter. They argue that the shooter simply maintains pressure while the trigger itself is forcibly reset by the firearm's action. Because the shooter's finger doesn't need to consciously release the trigger to fire the next round, the ATF considers the entire firing sequence to be the result of one 'function' of the trigger initiated by the shooter. This interpretation is highly contested and is the subject of ongoing legal battles across the country.

This contrasts with how semi-automatic firearms work, where the trigger must be released to reset the sear before the next shot can be fired. This release and subsequent pull is considered a separate function for each shot. The debate hinges on whether the shooter's constant rearward pressure on an FRT constitutes a single action, a distinction that has landed many gun owners in legal jeopardy.

Analyzing Idaho State Law

Idaho's state code addresses machine guns, but it largely mirrors the federal definition. Idaho Code § 18-3315, for example, restricts the possession of unregistered machine guns. The key here is that the state definition of a machine gun is effectively the same as the federal one. So, if a device is deemed a machine gun by federal authorities, it is also considered a machine gun under Idaho law. There is no special carve-out or protection for FRTs in the state's statutes.

Some might point to Idaho's Second Amendment Preservation Act as a potential shield. This law is designed to prevent state and local officials from enforcing federal gun control measures that are not mirrored in state law. However, this act does not and cannot stop federal agents from enforcing federal law within Idaho's borders. It also doesn't prevent state officials from cooperating with federal investigations in many cases. Relying on such a law as legal protection against a federal felony charge is an extremely risky proposition. The legal landscape for firearm accessories is constantly shifting, a reality seen in debates over binary triggers in Utah and other nearby states.

The practical reality for an Idaho gun owner is that possessing an FRT is a federal offense. While the chances of a local sheriff knocking on your door about it might be low, the risk of a federal inquiry is not zero. This is especially true if the firearm is brought to a public range or is involved in any incident that attracts law enforcement attention.

Technical Breakdown: FRT vs. Binary vs. Standard Triggers

The controversy surrounding FRTs is rooted in their unique mechanical function. A standard semi-automatic trigger requires a pull to fire and a release to reset. A binary trigger fires once on the pull and once on the release, requiring two distinct movements from the shooter's finger for the two shots. An FRT is different.

In an FRT-equipped firearm, the bolt carrier group's rearward motion after firing a round physically forces the trigger to reset. The shooter's job is simply to maintain rearward pressure on the trigger. As soon as the bolt is in battery, the reset trigger can be pressed again. Because this reset is nearly instantaneous, it allows for a rate of fire that can approach that of a fully automatic weapon. This rapid fire capability is precisely why the ATF has classified them as machine guns.

The distinction is subtle but critical. With a binary trigger, the shooter is still performing two voluntary actions (pull and release) for two shots. With an FRT, the ATF says the shooter performs one voluntary action (maintaining pressure) for a continuous, albeit interrupted, string of shots. This mechanical difference is the entire basis for the federal government's legal position.

Legal Risks and Practical Advice for Idahoans

The consequences of being caught with an unregistered FRT are severe. A conviction for possessing an unregistered machine gun is a federal felony that can result in up to 10 years in prison and fines of up to $250,000. It is a life-altering charge that strips an individual of their right to own firearms in the future.

Given the ATF's clear stance, possessing an FRT in Idaho is a significant legal gamble. While some owners may believe they are safe due to the state's pro-gun politics, federal law is the supreme law of the land in this matter. Ongoing lawsuits may eventually overturn the ATF's rule, but until a final decision is reached by the Supreme Court, the rule stands. Gun owners in other pro-gun states like Wyoming face the same dilemma, as detailed in the analysis of Wyoming's FRT laws.

For residents of Idaho, the safest course of action is to assume FRTs are illegal to possess. If you are considering acquiring any non-standard firearm component, it is essential to understand the process of how to buy a gun legally and ensure all parts comply with both state and federal regulations. Similarly, anyone looking to offload such a device must be aware that the process for how to sell a gun legally becomes much more complicated with NFA-regulated items. Do not attempt to buy, sell, or transfer these triggers through standard means. Consulting with a qualified firearms attorney is the only way to get reliable legal advice tailored to your specific situation.
