What Is a Forced Reset Trigger? An FRT Guide
Jun
A forced reset trigger (FRT) is an AR-15 trigger that uses the rifle’s own cycling action to push the trigger forward after every shot. That forced reset shortens the gap between rounds, so your follow-up shots come faster — but you still fire one round per trigger pull, which keeps the rifle semi-automatic. This guide explains what an FRT is, how it differs from other triggers, and what you need to run one.
At FRT Triggers USA, forced reset triggers are what we do, so here’s the plain-English version without the hype.

What is a forced reset trigger?
A forced reset trigger is a replacement fire-control system for AR-15-pattern rifles. The key word is forced: instead of relying on your finger to release and reset the trigger, the mechanism uses energy from the cycling bolt carrier to drive the trigger forward for you. Most modern FRTs are sold as a complete drop-in cassette, while selector-based designs (often called super safeties) achieve a similar effect through the safety selector.
How a forced reset trigger works
When you fire, the bolt carrier group travels rearward and then forward. In an FRT, that motion drives a cam or locking bar that forces the trigger to reset forward while you hold pressure on it. You then pull again for the next round. The result is a very short, consistent reset that lets a trained shooter fire quickly. For the full mechanical breakdown, see our guide on how a forced reset trigger works.
FRT vs standard, binary, and full-auto
| Trigger type | Rounds per action | Classification |
|---|---|---|
| Standard semi-auto | One per pull | Semi-automatic |
| Forced reset (FRT) | One per pull (faster reset) | Semi-automatic |
| Binary | One on pull, one on release | Semi-automatic |
| Machine gun | Multiple per single function | NFA / restricted |
The important distinction: an FRT still fires one round per trigger pull. That’s what separates it from a machine gun. If you want a head-to-head with binary triggers, read our forced reset trigger vs binary trigger comparison.
What you need to run a forced reset trigger
- A compatible mil-spec AR-15 lower (some selector-based systems need an FA pocket or low shelf).
- A full-auto bolt carrier group for consistent cycling.
- A heavier buffer — H2 at minimum, H3 recommended — for carbine builds.
- Anti-walk pins are a good idea to keep the assembly secure.
Get the support parts right and an FRT runs smoothly. Skimp on the buffer or carrier and you’ll chase reset problems.
Are forced reset triggers legal?
Under federal law in 2026, yes — after the May 2025 DOJ settlement with Rare Breed Triggers, FRTs are not classified as machine guns. Several states still restrict them, so confirm your own state and local law and check the ATF’s official guidance first. We cover this fully in are forced reset triggers legal?

Frequently asked questions
Is a forced reset trigger a machine gun?
No. It fires one round per trigger pull, which is the legal definition of semi-automatic. A machine gun fires more than one round per single function of the trigger.
How fast can you shoot with an FRT?
Faster than a standard trigger, because the reset is forced and very short. Your actual speed still depends on your technique and how well your build is set up.
What rifles accept a forced reset trigger?
Most are built for mil-spec AR-15 platforms. Some systems support additional platforms with a specific kit — always check compatibility for your build.
