Innovative Design and Features

3-Position Functionality: The FRT-15L3® (FLAT) features Safe, Semi, and Forced Reset modes, controlled via a 3-position, ambidextrous safety selector. Whether you’re focused on precision shooting or rapid-fire drills, this system adapts to your needs, offering versatility for both left- and right-handed shooters.
Effortless Installation: Designed for easy installation on Mil-Spec AR-15 lowers, the FRT-15L3® (FLAT) includes anti-walk trigger pins, providing secure attachment and preventing unwanted movement during extended use. The ambidextrous safety selector seamlessly integrates into any Mil-Spec lower receiver.
Single-Stage Trigger in Both Operating Modes

Semi-Automatic Mode: In Semi-Automatic mode, the trigger delivers a consistent, smooth 4–4.5 lb pull weight throughout the entire length of travel, from initial pressure to the break. This single-stage design provides a predictable trigger feel that promotes precise control and extremely fast follow-up shots.
Forced Reset (FRT®) Mode: In FRT® mode, the trigger maintains the same single-stage characteristic but with a slightly heavier 5.5–6 lb pull weight throughout the full length of travel.
Durable Construction for Long-Lasting Performance
Crafted from high-quality materials, including 7075 anodized aluminum and heat-treated 4140 steel, the FRT-15L3® (FLAT) is built to endure heavy use. This robust construction ensures reliability and longevity, allowing you to push your AR-15 to its limits with confidence.

AR-15 Compatibility
The FRT-15L3® (FLAT) is compatible with Mil-Spec AR-15 lowers and requires a full-auto-compatible bolt carrier group for proper functionality. For optimal performance, we also recommend using an H2 or H3 buffer, or alternatively, an A5 buffer system. Please note: The FRT-15L3® (FLAT) may not fit in certain Colt models or other lowers with a sear block/shelf.

Unmatched Speed and Control
The FRT-15L3® (FLAT) is ideal for shooters seeking speed and precision. By mechanically resetting the trigger after each shot, then locking the trigger from being pulled until the BCG returns to battery, this system allows for faster follow-up shots without needing advanced techniques. The forced reset mechanism ensures the trigger returns to the non-firing position after each round, requiring the shooter to pull the trigger again, offering full control over each shot.
