Let’s talk about the Rare Breed FRT-15 E3. This isn’t a trigger you buy on a whim. It’s a purpose-built piece of engineering for shooters who understand the mechanics of their rifle and want a specific, tangible performance difference. We stock it because it represents a significant piece of modern firearm design, and we believe in providing access to innovative components for knowledgeable builders.

Core Function: The FRT-15 is a forced-reset trigger (FRT). This is a mechanical function, not an electronic one. It uses the energy from your rifle’s recoil—specifically, the bolt carrier group moving forward into battery—to physically push the trigger back to the reset position. This mechanical interaction allows for a substantially faster shooting cycle compared to a standard semi-auto trigger, where your finger alone does all the work of release and reset.

Important Legal Disclaimer: The legal status of forced-reset triggers has been and continues to be subject to regulatory review and change. It is YOUR SOLE RESPONSIBILITY to understand and comply with all federal, state, and local laws regarding firearm components before purchasing. We cannot offer legal advice. By purchasing this item, you confirm you are of legal age, and that this component is legal to own and install in your jurisdiction.

What You Need to Know About This Trigger

Forget marketing hype. Here’s the straight talk on what the FRT-15 E3 is, what it does, and what it requires.

• It’s a Mechanical Marvel: The trigger group is machined from 7075-T6 aluminum billet. Internal components are wire-EDM cut and treated with a black nitride QPQ finish for hardness and corrosion resistance. This is a robust, precision-machined assembly, not a stamped-metal part.
• Three-Position Selector is Key: It comes with a proprietary safety selector. Positions are: SAFE, SEMI (functions like a standard semi-auto trigger), and HARD RESET (engages the forced-reset mechanism). You choose the mode for your needs.
• Demands a Properly Tuned Rifle: This trigger is not a magic box. To run reliably, your AR-15 needs to be in spec. This includes correct gas system pressure, a properly functioning bolt carrier group, and a buffer system that isn’t under or over-sprung. It works best with a carbine-length gas system and standard carbine buffer weight. Over-gassed or under-gassed rifles will cause malfunctions.
• Installation Matters: While it drops into a standard AR-15 lower receiver, alignment and pin fit are critical. The included anti-walk pins are mandatory for use. We strongly recommend installation by or final inspection from a competent gunsmith to ensure proper sear engagement and function.
• What It Is Not: It is not a “auto-sear” or a “lightning link.” It does not convert your rifle into a machine gun. Its operation is dependent on a specific, continuous mechanical interaction between the shooter’s maintained pressure and the rifle’s cycle. Releasing finger pressure stops the cycle.

Who This Is For (And Who It Isn’t)

Consider this trigger if: You are an experienced shooter with a deep understanding of AR-15 mechanics. You have a well-tuned, reliable rifle and want to explore the mechanical limits of the platform. You appreciate innovative engineering and are willing to ensure your firearm is set up correctly to match the component.

Look elsewhere if: You are a novice builder, your rifle isn’t 100% reliable with a standard trigger, or you’re looking for a simple “plug-and-play” upgrade without any tuning or learning curve. This is not a beginner’s part.

Frequently Asked Questions

Q: Is this a binary trigger?
A: No. A binary trigger fires on pull and release. The FRT-15 is a forced-reset trigger. It fires on pull, and the rifle’s action physically resets the trigger while your finger maintains rearward pressure. Releasing your finger stops the action.

Q: Will this work in my pistol-caliber AR (9mm, .45 ACP) or .308 AR?
A: Generally, no. These platforms often have different bolt carrier group weights and cycling characteristics that are not compatible with the F
