Rare Breed FRT-15L3: The Gold Standard 3-Position Trigger
Take absolute control of your AR-15 with the Rare Breed FRT-15L3. This is the official, duty-grade evolution of the forced-reset platform. Offering a versatile 3-position selector (Safe/Semi/FRT®), the L3 allows you to switch between traditional precision and high-cadence fire at a moment’s notice. 100% manufactured and assembled in the USA, this kit includes everything you need for a rock-solid, professional installation.
Range Performance & Innovation
The FRT-15L3™ is engineered for shooters who demand speed without compromise. By utilizing an innovative mechanical reset, the trigger is actively pushed back to the “set” position as the bolt carrier returns to battery.
The Result: Faster splits, consistent rhythm, and a shooting experience that bridges the gap between semi-auto and high-performance tactical platforms.
Legal Compliance: Every trigger pull fires exactly one round, ensuring the unit remains a semi-automatic component while delivering unparalleled performance.
Key Product Features
3-Position Versatility: Includes a custom ambidextrous safety selector to toggle between Safe, Semi, and Forced Reset modes.
Single-Stage Precision:
Semi Mode: A smooth, predictable 4–4.5 lb pull for precision work.
FRT® Mode: A tactical 5.5–6 lb pull optimized for high-cadence control.
Built for Punishment: Constructed from 7075-T6 anodized aluminum and heat-treated 4140 tool steel to endure high-volume range sessions.
Anti-Walk Hardware: Includes premium anti-walk pins to keep your fire control group secure under the increased vibrations of rapid fire.
Critical Compatibility Requirements
To ensure “out-of-the-box” reliability, your build must meet the following specifications:
BCG: Requires a Full-Auto / M16 Profile Bolt Carrier Group.
Buffer System: Highly recommended to use an H2, H3, or A5 buffer system to prevent bolt bounce and ensure proper timing.
Lower Receiver: Fits most MIL-SPEC lowers. Note: Will not fit Colt models or lowers featuring a sear block/shelf.
Why Upgrade to the FRT-15L3™?
This isn’t just a “range toy”—it’s a precision-engineered upgrade for competitive shooters and tactical enthusiasts. By mechanically locking the trigger until the BCG is in battery, the FRT-15L3™ eliminates the risk of “out-of-battery” malfunctions and allows for incredible follow-up speed without the need for advanced finger techniques.
