FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15

The FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 represents a refined evolution in trigger design from Rare Breed. If you have handled earlier forced reset triggers, you will notice the difference immediately. The flat shoe offers a consistent, neutral finger placement that reduces pull variation, especially during rapid strings. This is a single-stage, three-position unit: safe, semi-automatic, and forced reset. The forced reset position delivers a distinct mechanical cycle that returns the trigger forward after each shot, requiring you to reset it manually. It is not a binary trigger and does not modify the firearm’s semi-automatic classification, but the tactile feedback is unique and demands a deliberate shooting rhythm.

Overview

Rare Breed designed the FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 for shooters who want a responsive, predictable trigger without the mushiness of a standard mil-spec unit. The flat face reduces over-travel and keeps your finger indexed consistently. The forced reset function is mechanically straightforward: after each hammer fall, the trigger is pushed forward by the bolt carrier group, requiring you to release and re-press for the next shot. This creates a faster split time potential, but it demands proper technique. It is compatible with standard AR-15 lower receivers and does not require permanent modification to the firearm.

Features & Specs

This trigger is built to handle extended range sessions and varied ammunition types. The components are machined from billet steel and treated with a corrosion-resistant finish. The flat shoe is contoured for gloved or bare-hand use. Below are the key specifications:

• Manufacturer: Rare Breed. Category: Triggers. Single-stage, three-position selector (Safe, Semi, Forced Reset).
• Flat trigger shoe with a wide, serrated face for consistent finger placement and reduced slip.
• Drop-in design using factory-style pins; no proprietary tools or permanent lower modification required.

Additional features worth noting:

• Hammer and trigger are heat-treated to military-grade hardness specifications for long service life.
• The forced reset function relies on the bolt carrier’s forward motion to reset the trigger, which is a purely mechanical interface.
• Includes anti-walk pins to prevent trigger movement during high-round-count sessions.

For those who have not used a forced reset trigger before, understand that the FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 requires a slightly different grip and trigger finger discipline compared to a standard trigger. The learning curve is short, but it is real.

Who It’s For

This trigger is for the shooter who has already mastered basic AR-15 operation and wants to push their split times without switching to a binary or full-auto setup. It is ideal for competitive shooters in divisions that allow three-position selectors, or for hobbyists who enjoy mechanical precision and want a more engaging range experience. If you are a first-time AR builder or prefer a traditional two-stage trigger, this may not be the right choice. But if you understand the mechanics and want a trigger that rewards consistent technique, this is a solid option. The forced reset action is not for everyone, but it is a legitimate tool for shooters who train deliberately.

Shipping & FFL

This trigger ships directly to your door. No FFL transfer is required because it is not a firearm or a firearm receiver. It is a drop-in trigger assembly and is treated as a firearm component under federal law. However, we recommend checking your state and local regulations before ordering, as some jurisdictions have restrictions on forced reset triggers or select-fire components. Rare Breed explicitly states that this trigger is designed for semi-automatic AR-15s and does not convert the firearm to full-auto.
