Are Forced Reset Triggers Legal in California? A Deep Dive…

Are FRTs Legal in California?

No, forced reset triggers (FRTs) are illegal in California. The state's definition of a machine gun, found in Penal Code section 16930, includes any part designed to convert a weapon to fire automatically. This broad definition, combined with a similar federal ATF ruling, effectively bans FRTs.

Understanding the Core Technology: What is a Forced Reset Trigger?

A forced reset trigger, or FRT, is a firearm component designed to replace a standard semi-automatic trigger group, most commonly in AR-15 style rifles. Its primary function is to dramatically increase the potential rate of fire. Unlike a standard trigger where the shooter's finger must consciously move forward to reset the trigger for the next shot, an FRT uses the energy from the reciprocating bolt carrier group to mechanically force the trigger to reset.

Here’s how it works: after a round is fired, the bolt carrier group moves rearward and then forward to chamber the next round. During this forward movement, a component of the FRT uses that force to push the trigger forward, resetting it instantly. The shooter's finger essentially acts as a backstop. By maintaining steady rearward pressure on the trigger, the rifle will fire as fast as the bolt carrier group can cycle. This operation is the entire basis for the legal controversy surrounding these devices.

The California Legal Framework: Penal Code 16930

The central piece of legislation governing FRTs in California is Penal Code section 16930. This statute defines what constitutes a 'machinegun' within the state, and its language is intentionally broad. The law states that a machinegun is not just a firearm that shoots automatically, but also includes 'any part designed and intended solely and exclusively, or combination of parts designed and intended, for use in converting a weapon into a machinegun.'

This is the critical phrase. The California Department of Justice interprets FRTs as a 'combination of parts designed and intended' to convert a semi-automatic rifle into a weapon that fires automatically. The state's legal interpretation does not require the weapon to be a machine gun in the traditional, military sense. Instead, it focuses on any device that allows for an automatic rate of fire through a single function of the trigger. Because an FRT enables continuous fire with a single, continuous rearward pressure on the trigger, it falls under this expansive definition, making it illegal to possess, sell, or manufacture in California.

The Federal Overlay: ATF's Position on FRTs

California's strict stance is mirrored at the federal level. The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) has issued open letters clarifying its position on FRTs. The ATF concluded that some FRTs meet the definition of a 'machinegun' under the National Firearms Act (NFA) and Gun Control Act (GCA).

The ATF's reasoning is that a 'single function of the trigger' means a single pull. They argue that with an FRT, the shooter's single act of pulling and holding the trigger results in a continuous firing cycle. The subsequent shots are fired without an additional, separate pull of the trigger by the shooter. Therefore, the device is legally a machine gun. This federal classification is binding on all Federal Firearms Licensees (FFLs) and residents, creating a second, insurmountable legal barrier to owning an FRT in California. The legal situation in other states can be different; for example, the laws for FRTs in Texas also have to contend with this federal ruling.

Even if one were to argue a nuance in California's state law, the ATF's federal classification makes possession illegal everywhere in the U.S. without proper NFA registration, which is not possible for these devices. The process for a legal firearm purchase is already detailed, and adding a prohibited device creates massive legal jeopardy.

FRT vs. Bump Stock: A Legal Comparison in California

It's helpful to compare the legal status of FRTs to that of bump stocks. California explicitly banned bump stocks by name under Senate Bill 880. However, the absence of the specific term 'forced reset trigger' in California law does not make them legal. This is a common and dangerous misconception.

The law operates on definitions, not just named items. While bump stocks are banned by name, FRTs are banned by function. They fall under the pre-existing, broader definition of a machine gun in PC 16930. The legal outcome is the same: possession is a felony. This is a crucial distinction for gun owners to understand. Lawmakers do not need to pass a new law for every new invention; if a device meets an existing legal definition of a prohibited item, it is already illegal.

Consequences of Possession: Felonies and Firearm Rights

The penalties for possessing an unregistered machine gun, which includes a rifle equipped with an FRT, are severe in California. A violation of PC 32625 (possession of a machine gun) is a felony. A conviction can result in imprisonment for 16 months, two, or three years, and substantial fines.

Beyond incarceration and fines, a felony conviction means the permanent loss of your Second Amendment rights. You would be prohibited from owning or possessing any firearms or ammunition for life. This applies even if the FRT is not installed in a firearm. Simply possessing the trigger itself is considered possession of a machine gun part under PC 16930. Given the risks, it's far better to invest in legal high-performance firearms, such as a well-regarded platform like the SIG Sauer MPX, than to experiment with legally dubious parts. Understanding the value of a legal firearm is diminished entirely by an illegal modification.

Gray Areas and Common Misconceptions

A frequent but incorrect argument in favor of FRT legality is the 'one pull, one shot' claim. Proponents argue that since the trigger does technically move forward for each shot, it's not automatic fire. However, both the California DOJ and the federal ATF reject this mechanical distinction. Their legal interpretation focuses on the action of the shooter. Since the shooter's finger remains static after the initial pull, they classify the subsequent shots as part of a single trigger function, thus making it an automatic weapon.

It is also important not to confuse the laws of different states. While some states may have more ambiguous laws, the legal landscape in California is very clear on this matter. The situation is not the same as it is for FRT owners in Florida or other less restrictive states. For California residents, there is no legal gray area to exploit. The combination of a broad state definition of a machine gun and a clear federal ruling makes possession of an FRT a significant legal risk. Anyone looking for firearms should stick to the many legal options available through standard marketplace listings.
