About this product

The FRT-15L3 is Rare Breed Triggers' drop-in, duty-grade forced reset trigger for the AR-15 platform, available in curved or flat trigger shoe versions at the same price. Before anything else: the legal status of forced reset triggers has been the subject of active federal litigation and regulatory action, and California has separately restricted this category of device under state law — read the compliance section below carefully before purchasing.

What does a forced reset trigger actually do?

A forced reset trigger is designed to mechanically reset the trigger to its forward position after each shot using the bolt carrier's rearward movement, rather than relying on the shooter's finger to fully release the trigger between shots. Rare Breed markets the FRT-15L3 as a single-stage, 3-position (Safe/Semi/FRT) trigger that still fires one round per trigger pull, with a pull weight of about 4 to 4.5 pounds in standard semi-automatic mode and roughly 5.5 to 6 pounds in forced-reset mode.

What is the FRT-15L3 built from, and what does it require?

The trigger housing uses 7075 anodized aluminum with heat-treated 4140 steel internals, and it includes a 3-position ambidextrous safety selector and anti-walk pins for installation. Rare Breed states it requires a full-auto-compatible bolt carrier group to function as designed, along with an H2 or H3 buffer recommended for carbine-length builds — this is not a simple drop-in for every AR-15 build without checking compatible components first.

Is the FRT-15L3 legal to own?

This is the single most important question to answer before buying. Forced reset triggers, including Rare Breed's FRT-15 line, have been the subject of ongoing federal legal disputes over whether the ATF can classify them as machine guns, and the regulatory and legal status has shifted multiple times through litigation. Separately, California has enacted its own state-level restrictions on multi-burst trigger activators and forced reset trigger devices, which may make possession of this product illegal for California residents regardless of the outcome of federal litigation. Do not purchase or install this product until you have independently confirmed its current legal status under both federal law and California law — including consulting a firearms attorney if there is any doubt — since owning a prohibited device can carry serious legal consequences.

Does this ship directly to me?

As a trigger component rather than a complete firearm, this product is typically sold direct-to-consumer without an FFL transfer. That distribution model does not change its legal status where it is separately restricted or prohibited — buyers remain fully responsible for confirming legality in their own state before ordering or installing it.

Who should consider this product?

Given the unsettled legal landscape, this is a product that requires buyers to do their own independent legal research before purchasing, particularly California residents. We are not able to advise on the legality of this specific device in your jurisdiction — confirm current status with a qualified firearms attorney or your local ATF field office before ordering.

What should California residents specifically know?

California has enacted its own statutory restrictions on multi-burst trigger activators and forced reset trigger devices that operate independently of whatever the federal courts eventually decide about ATF's machine-gun classification. That means a favorable outcome in federal litigation would not automatically make this device legal to own in California if a separate state prohibition remains in effect. California buyers in particular should treat this as a jurisdiction where the answer may simply be no, and should confirm that directly with a firearms attorney rather than relying on this listing or general online discussion.

Given the seriousness of the compliance questions involved, treat this listing as informational and verify current legal status thoroughly before purchasing.

Not available in California

California classifies forced-reset triggers as multiburst trigger activators under Penal Code sections 16930 and 32900. They cannot be sold, shipped or possessed in California, and this remains the case regardless of the current federal position. We cannot ship this item to a California address. Buyers in other states are responsible for confirming their own state and local law before ordering.
