Rare Breed Triggers FRT-15C3™ Two-Stage Forced Reset Trigger

Price: $451.00

Let’s cut through the noise and talk about what the Rare Breed FRT-15C3 actually is, what it does, and why it’s a serious piece of engineering for the serious shooter. This isn’t magic, it’s mechanics.

How a Forced Reset Trigger Works: The Straight Talk

To get why the FRT is different, you need to know how your standard AR-15 trigger works. In a mil-spec fire control group, you have a disconnector. When you pull the trigger and fire a round, the bolt carrier group cycles. As it comes forward, it trips the disconnector, which catches the hammer and holds it back—even if you’re still holding the trigger down. To fire again, you must release the trigger enough to let the disconnector reset, re-engaging the trigger and sear. Only then can you pull for the next shot. That’s the “reset” you feel.

The FRT-15C3 changes that interaction. Its patented mechanism uses the energy of the bolt carrier group cycling to physically force the trigger forward against your finger, completing that reset for you. The key is this: it does this while the bolt is locking into battery. The trigger is mechanically blocked from being pulled again until the bolt is fully in battery, ensuring one cycle per operation.

The Practical Result: By maintaining steady, constant rearward pressure on the trigger, the firearm will cycle as fast as the bolt can complete its full travel and lock. This allows for a dramatically increased rate of controlled fire. It fires one round per trigger function. You pull, it fires, it forces itself forward against your finger, and your maintained pressure immediately begins the next pull. It requires a consistent, firm hold. Jerk or flinch, and you’ll interrupt the cycle.

FRT-15C3™ Specifications & Features

• 3-Position Selector: Safe | Semi | FRT. Comes with a 3-position ambidextrous safety selector for left or right-handed use.
• Two-Stage Semi Mode: A clean, predictable two-stage pull. Approximately 2.5 lbs take-up, a defined wall, and a 2 lb break for a total of around 4-4.5 lbs. Excellent for precision work.
• FRT Mode: A heavier, consistent single-stage pull weight of 5-5.5 lbs throughout the travel. This weight is by design for control and reliability.
• Duty-Grade Construction: Made in the USA from 7075-T6 aluminum and heat-treated S7 tool steel. This thing is built to last.
• Secure Installation: Includes anti-walk pins to keep the trigger group solidly in place, round after round.
• Drop-In Design: Installs in a mil-spec AR-15 lower with basic tools. No gunsmithing required.

What You NEED for It to Run Right

This isn’t a “plug and play and forget” part. It’s a precision system that requires your rifle to be in spec. Here are the non-negotiable requirements and strong recommendations:

• MIL-SPEC AR-15 Lower Receiver: Must be a standard, mil-spec lower. It will NOT fit Colt-style lowers or others with a sear block/shelf.
• Full-Auto Compatible Bolt Carrier Group: You MUST use a full-auto profile BCG (often called an M16-style BCG). The mechanism interacts with the auto sear trip shelf on the bottom of the carrier. A semi-auto-only carrier will not work.
• Heavier Buffer System (STRONGLY Recommended): To properly time the cycle and ensure reliable function, you need to slow your bolt carrier down. We recommend an H2 or H3 buffer, or an A5 buffer system. Running a standard carbine buffer will likely cause malfunctions and excessive wear.
• Proper Maintenance & Lubrication: A clean, well-lubed rifle is critical for the consistent timing this trigger demands.

Who This Trigger Is For

This is a trigger for experienced shooters who understand their platform. It’s for the guy who wants to shave tenths of a second off drills, who practices dynamic shooting, and who appreciates innovative mechanical design. It’s a phenomenal training tool for practicing trigger control under rapid fire—because if you lose that steady pressure, the shooting stops. It’s also just plain fun for turning money into noise at the range in a controlled, deliberate manner.

Legal Disclaimer: The FRT-15C3 is designed to fire one round per function of the trigger. It is the shooter’s constant pressure that initiates each subsequent function. It is the responsibility of the purchaser to understand and comply with all federal, state, and local laws regarding firearm components. Always use safe firearm handling practices.

Bottom Line

The Rare Breed FRT-15C3 isn’t an incremental upgrade. It’s a fundamental change to the fire control system that offers a unique and highly effective shooting experience. If you’re looking to push the mechanical limits of your AR-15’s rate of fire while maintaining control and compliance, this is the trigger you’ve been hearing about. Built tough, made in America, and engineered without compromise.
