Are Forced Reset Triggers Legal in South Carolina? 2026

Are FRTs Legal in South Carolina?

No. While South Carolina state law does not explicitly ban forced reset triggers, they are illegal to possess under federal law. The ATF classifies FRTs as machine guns, making their possession without proper NFA registration a federal felony. This federal ruling effectively makes FRTs illegal in South Carolina.

The Federal Mandate: ATF Rule 2021R-05F

The central issue concerning forced reset triggers (FRTs) in South Carolina, and indeed the entire country, stems from federal regulations, not state-level legislation. The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) issued a ruling, often cited in conjunction with an open letter from March 2022, clarifying its position on these devices. The agency determined that FRTs fall under the definition of a 'machinegun' as defined by the National Firearms Act (NFA) of 1934 and the Gun Control Act (GCA) of 1968.

According to the ATF, a machine gun is 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. The ATF's interpretation hinges on the phrase 'single function of the trigger.' With an FRT, the shooter depresses the trigger, and the bolt carrier group's forward motion forces the trigger to reset. The ATF argues that this entire cycle—the initial pull and the forced reset—constitutes a single function, allowing for continuous fire as long as the shooter maintains pressure. Therefore, in the eyes of the federal government, these devices are not semi-automatic accessories but machine gun conversion devices.

This federal classification is the most critical piece of the puzzle. It means that regardless of what South Carolina's state statutes say or do not say, the possession, sale, or transfer of an FRT is treated as an unregistered machine gun, a serious federal offense. This federal oversight effectively creates a nationwide ban for the average citizen.

Dissecting South Carolina's State Firearms Laws

When examining the South Carolina Code of Laws, one finds no specific mention of 'forced reset triggers.' The state legislature has not passed a bill explicitly outlawing these devices by name. The relevant section to consult is Title 16, Chapter 23, which covers offenses involving weapons. Specifically, S.C. Code § 16-23-210 provides the state's definition of a 'machine gun.'

The South Carolina definition is very similar to the federal one, stating a machine gun is '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.' It also includes the frame, receiver, and any part designed for converting a weapon into a machine gun. While the state's definition is parallel to the federal one, South Carolina law enforcement and prosecutors typically defer to ATF classifications on matters of firearm mechanics and function.

This means that while a local prosecutor wouldn't find a state law called the 'Forced Reset Trigger Ban,' they would likely prosecute under the existing state machine gun statute by citing the ATF's technical determination. The federal ruling provides the legal and technical basis for considering an FRT a machine gun part.

How a Forced Reset Trigger Actually Works

To understand the legal controversy, it's essential to grasp the mechanics of an FRT. A standard semi-automatic trigger, like a mil-spec AR-15 trigger, requires the shooter to pull the trigger to fire a round. To fire the next round, the shooter must consciously release the trigger to allow it to reset before it can be pulled again. The speed of fire is limited by how quickly the shooter can perform this pull-release-pull sequence.

A forced reset trigger fundamentally alters this process. An FRT uses a mechanism that harnesses the energy of the recoiling bolt carrier group (BCG). When the shooter pulls the trigger, a round is fired and the BCG cycles to the rear. As the BCG returns forward to chamber the next round, a component of the FRT uses this forward momentum to physically and audibly push the trigger forward, resetting it. The shooter's finger is pushed forward along with it. This allows for an extremely rapid rate of fire because the reset is nearly instantaneous and is performed by the firearm's action, not the shooter's finger muscles.

The legal debate centers on whether the shooter's constant rearward pressure on the trigger, while the trigger itself is being forced forward and back, constitutes a 'single function' for multiple shots. Proponents argue it's still one shot per trigger movement, while the ATF contends it's one continuous action by the shooter resulting in automatic fire. Understanding these mechanics is crucial for anyone looking into customizing their firearm, a key step in the process of how to buy a gun that fits their needs.

Legal Challenges and the Current Landscape

The ATF's classification of FRTs has not gone unchallenged. Manufacturers, most notably Rare Breed Triggers and Wide-Open Triggers, have been embroiled in extensive legal battles with the federal government. These companies argue that the ATF overstepped its authority by reclassifying a legal accessory as a machine gun without any change in the underlying law passed by Congress. They maintain their products are mechanically semi-automatic, as the trigger does reset and must be actuated for each shot.

These court cases have seen mixed results, with different courts issuing conflicting injunctions and rulings. The legal situation is reminiscent of the battle over bump stocks, which culminated in the Supreme Court case *Garland v. Cargill*. While that case dealt with a different device, the core legal question about an agency's power to interpret statutory definitions like 'machine gun' is highly relevant. As of now, the ATF's rule remains in effect and is being enforced across the country.

For a gun owner in South Carolina, this means the legal environment is defined by federal enforcement priorities and the ongoing, unresolved court battles. This federal-level scrutiny isn't unique to South Carolina; gun owners in other states are facing similar legal questions, as seen in the debate over forced reset triggers in Wisconsin. Until federal courts or the Supreme Court issue a definitive, final ruling, the ATF's classification stands as the prevailing law.

Risks and Penalties for Possession in South Carolina

The consequences of possessing an FRT in South Carolina are severe due to its federal status as an unregistered machine gun. A violation of the National Firearms Act is a felony. A conviction can result in up to 10 years in federal prison, fines of up to $250,000, and the permanent loss of firearm rights. These are not minor infractions; they are life-altering penalties.

It is crucial for firearm owners to understand that ignorance of the ATF's ruling is not a valid legal defense. Federal law enforcement agencies are actively investigating and prosecuting individuals and companies involved in the sale and possession of these devices. These harsh penalties underscore the importance of understanding the law before you list a firearm or accessory for sale, to avoid inadvertent federal violations.

Because the device itself is considered the machine gun, simply owning one, even if it is not installed in a firearm, constitutes possession of an unregistered NFA item. There was no amnesty or registration period offered for FRTs, so any device in civilian hands is, by definition, contraband in the eyes of the ATF. Navigating the different types of firearms and accessories available requires staying informed about current regulations, which is why it's wise to regularly browse all gun listings to see what is legally being traded.

Given the clear federal prohibition and the severe penalties involved, the legal consensus is that possessing a forced reset trigger in South Carolina is an unacceptable risk. While the state may not have a specific law on the books, federal law is clear and actively enforced.
