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

Rare Breed FRT-15L3: The Ultimate 3-Position Forced Reset Upgrade

The standard has been elevated. If you want to maximize your AR-15’s potential for competitive shooting, intense tactical training, or rapid-fire range drills, the Rare Breed FRT-15L3 is the definitive choice. Unlike older legacy iterations, the FRT-15L3™ features a true, robust 3-position ambidextrous safety selector, giving operators total tactical control over their firing schedule. Switch cleanly from a locked safe position to a crisp, predictable standard semi-auto pull, or click into high-speed Forced Reset mode to experience unparalleled speed and control.

True Single-Stage Crispness in Every Mode

Rare Breed Triggers designed the Rare Breed FRT-15L3 to operate with consistent, predictable single-stage characteristics across both active firing options:

• Semi-Automatic Mode: Delivers a smooth, highly precise 4 to 4.5 lb pull from the initial wall straight through to a clean break. This predictable behavior is optimized for precision shot placement and fast, traditional tracking.

• Forced Reset (FRT®) Mode: Maintains the identical crisp, single-stage geometry but elevates to a firmer 5.5 to 6.0 lb pull weight. This intentionally robust resistance ensures distinct mechanical separation for every cycle under high-speed operation.

Innovative High-Speed Mechanical Geometry

How does the FRT-15L3 achieve its legendary cyclic rates? The system utilizes the rearward kinetic energy of your rifle’s bolt carrier group (BCG) to physically and mechanically force the trigger forward against your finger as the action cycles.

By instantly pushing the trigger into a reset position the exact millisecond the next round chambers—and mechanically locking it from breaking until the BCG fully returns to battery—you can squeeze off follow-up shots at incredible speeds without relying on complex bump-firing or advanced finger techniques. Every round fired requires its own separate, intentional pull of the trigger, keeping the unit firmly within compliant semi-automatic operating parameters.

Built for the Hardest Duty Schedules

Cheap alternatives cannot survive the intense cyclic pressure of forced reset mechanics. That is why the Rare Breed FRT-15L3 is built from an elite combination of a rugged 7075 anodized aluminum housing and core components machined out of heat-treated 4140 steel. To prevent the pins from backing out or egging your lower receiver holes under sustained fire, the unit comes standard with premium anti-rotation, anti-walk trigger pins for absolute security.

Critical Platform Compatibility Notes

The Rare Breed FRT-15L3 is a true drop-in fire control group designed to slide seamlessly into standard MIL-SPEC AR-15 lower receivers. To ensure flawless timing and prevent short-cycling or dead triggers, please verify your rifle meets these technical guidelines:

1. Bolt Carrier Group: You must run an unrestricted, full-auto profile (M16 style) BCG so the bottom shroud can properly trip the internal reset mechanical bar.

2. Buffer Weights: Due to the elevated cycling speed, we highly recommend tuning your lower receiver with an H2 or H3 heavy buffer, or a premium A5 buffer system.

3. Receiver Caveat: Will not drop into proprietary Colt lower receivers or non-standard lowers that feature an integrated sear block or shelf.
