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 precision-engineered upgrade to your platform. Manufactured by Rare Breed, this trigger system is designed for shooters who demand consistent forced-reset functionality without compromising on control. Leveraging a flat shoe geometry, the FRT-15L3 reduces finger drag and provides a more predictable pull surface during rapid fire sequences. This is not a binary trigger; it is a forced-reset system that requires the shooter to maintain forward pressure on the trigger shoe to cycle the action. Each unit is built to MIL-SPEC dimensions for drop-in compatibility with standard AR-15 lower receivers.

Overview

Rare Breed has refined its forced-reset design with the FRT-15L3, offering a three-position selector that gives the operator explicit control over fire mode: safe, semi-automatic, and forced-reset. The flat trigger profile is a direct response to competitive shooters and tactical users who prefer a consistent finger placement across the shoe. Unlike curved triggers that can cause off-axis pull, the flat shoe on the FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 ensures linear rearward travel. This trigger is manufactured from heat-treated steel with a corrosion-resistant finish, and it includes all necessary pins and springs for installation. The unit is designed to work with 9mm, .223 Remington, and 5.56 NATO chambered AR-15s, provided the bolt carrier group meets standard weight specifications.

Features & Specs

This forced-reset trigger system is built around three core mechanical attributes. First, the single-stage design eliminates take-up, providing a crisp break point at every cycle. Second, the forced-reset mechanism physically returns the trigger shoe forward after each shot, requiring the shooter to release and reapply pressure. Third, the flat shoe is machined with a serrated face to reduce slippage under rapid manipulation.

• Three-position selector: Safe, Semi-Automatic, Forced Reset. Each position is clearly indexed with positive detent engagement.
• Flat trigger shoe with 0.20-inch width, serrated face, and an overall weight of 2.8 ounces. Pull weight is factory-set between 4.5 and 5.5 pounds.
• Drop-in installation: No gunsmithing required. Includes anti-walk pins, trigger return spring, and hammer spring. Compatible with all standard AR-15 lower receivers.

Additional specifications include a hammer-forged steel construction with a nitride finish for wear resistance. The trigger group is tested to 20,000 cycles with no degradation in forced-reset performance. The FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 is compliant with all federal regulations as of the date of manufacture. Rare Breed provides a limited lifetime warranty against manufacturing defects.

Who It’s For

This trigger system is intended for experienced AR-15 owners who understand the mechanics of forced-reset operation. It is not recommended for first-time builders or shooters unfamiliar with trigger discipline under rapid fire. The FRT-15L3 (Flat) Single-Stage (3-Position) Forced Reset Trigger for the AR-15 is ideal for competitive shooters in limited-class events that permit forced-reset devices, as well as for range enthusiasts who want to train trigger reset speed without modifying bolt carrier groups. Law enforcement armorers and civilian marksmen who prioritize trigger consistency over pull weight reduction will find this unit reliable. It is not designed for fully automatic use and will not function as a machine gun conversion device.

• Competitive shooters: Suitable for USPSA, 2-Gun, and 3-Gun divisions that allow forced-reset triggers. Flat shoe aids in indexed finger placement during stage transitions.
• Tactical trainers: Maintains semi-automatic functionality in position 2, allowing for standard fire mode training with forced-reset option for reset practice.
• Experienced builders: Requires proper buffer weight and spring selection. Recommended for carbine-length gas systems with H2 or heavier buffers for consistent cycling.
