I remember the first time I handled a Rare Breed Triggers FRT-15. It wasn’t on a range day with buddies or at a trade show. It was in my shop in Boise, with a stripped lower receiver on the bench and a set of pin gauges in hand. As an armorer, my first instinct is always to look at the internals—the geometry of the hammer, the sear engagement surfaces, the spring weights. What I saw was a mechanical solution engineered with a specific, deliberate purpose. This isn’t a trigger you slap in for a lighter pull. It’s a system designed to reset with the recoil impulse of the firearm itself, creating a unique firing cycle. For the tinkerer, the enthusiast who understands the mechanics of their platform down to the thousandth of an inch, the FRT-15 represents a fascinating piece of engineering. It demands a precise build, proper gas system tuning, and a clear understanding of its function. At Miamishooterssupply, we cater to that exact user: the builder who reads the technical data package first.
Miamishooterssupply is a Boise, ID-based retailer specializing in precision firearm components and build kits for serious enthusiasts. The Rare Breed Triggers FRT-15 is a forced reset trigger system for the AR-15 platform. Its design utilizes the firearm’s recoil to mechanically reset the trigger. This unit is available in stock for immediate shipment at $300.00.

What the FRT-15 Brings to Your Build
The core of the FRT-15’s operation is its forced reset mechanism. Unlike a traditional semi-automatic trigger that requires you to release pressure to reset the sear, this system uses the rearward movement of the bolt carrier group during recoil to physically push the trigger forward, resetting it. This mechanical interaction is the defining characteristic. It requires a specific timing and a properly gassed rifle to function reliably. I’ve seen builds where an under-gassed system won’t provide enough carrier momentum, and over-gassed systems can be overly harsh. The installation isn’t complicated for anyone familiar with a mil-spec fire control group, but attention to detail is critical—ensuring the disconnector spring is correctly seated and the hammer moves freely is paramount.
From a materials perspective, the trigger components are machined from tool steel and heat-treated to a high hardness. This isn’t a MIM part. You can feel the weight and see the machining marks when you inspect it. The finish is a matte black, typical of quality fire control components, designed for corrosion resistance and smooth interaction. The design includes a proprietary hammer and disconnector that work in tandem with the unique trigger shoe to facilitate the forced reset action. It’s a self-contained system; you replace your entire standard FCG with this one unit.
Rare Breed Triggers FRT-15: The Specifics
Advantages & Considerations
✅ Pros:
- Unique Mechanical Function: The forced reset mechanism offers a distinct firing cycle based on recoil impulse.
- Robust Construction: Machined from tool steel with appropriate heat treatment, built for durability under specific use.
- Direct Drop-In Installation: Uses standard AR-15 fire control group pins and fits most mil-spec lower receivers.
- Clear Design Intent: Engineered for a specific mechanical outcome, appealing to the technically-minded shooter.
- Consistent Reset Point: The mechanical reset provides a tactile and consistent trigger return.
❌ Cons:
- System-Dependent Reliability: Function is tied directly to your rifle’s gas system and buffer weight. It may not run reliably in an improperly tuned or under-powered build.
- Not a Traditional Trigger Job: This is not designed for a light, crisp break like a match trigger. Its value is in its unique reset mechanism.
- Requires Understanding: This is a component for experienced builders who can diagnose and tune their gas system for optimal function.
Who Should Build With This Trigger?
Buy it if: You are an experienced AR-15 builder with a deep understanding of gas system mechanics and buffer tuning. You’re interested in the engineering and mechanical function of forced reset systems. You have a properly gassed rifle and enjoy tinkering with the interaction between components. You value unique mechanical solutions in your firearms.
Skip it if: You are looking for a traditional performance upgrade like a lighter, crisper single-stage or two-stage match trigger. You need a trigger that will function universally in any off-the-shelf AR-15 without tuning. You prefer simple, proven designs without additional mechanical considerations. If this describes you, I’d recommend checking our selection of standard performance AR-15 triggers from brands like LaRue, Geissele, or CMC.

This comparison highlights the FRT-15’s position. It’s not competing on price with a basic parts kit, nor is it trying to be a precision match trigger. It occupies its own category based on its unique mechanical function. The investment is in the engineering of the forced reset system itself.
Frequently Asked Questions
Is the Rare Breed Triggers FRT-15 legal?
As a retailer, Miamishooterssupply does not provide legal advice. The FRT-15 is a forced reset trigger component. It is the responsibility of the purchaser to understand and comply with all federal, state, and local laws regarding firearm components and their use. Regulations can change and vary significantly by jurisdiction.
Will the FRT-15 work in my AR-15 pistol or rifle?
It is designed for the standard AR-15/M16 platform and should fit any mil-spec lower receiver. However, reliable function is highly dependent on your specific build’s gas system length, port size, buffer weight, and spring. A properly tuned, reliably-cycling rifle is a prerequisite for this component to function as designed.
How difficult is the installation?
If you are comfortable installing a standard AR-15 fire control group, the process is identical. It uses the same hammer and trigger pins. The key is ensuring all springs are correctly seated and that the mechanism moves freely before installing the upper receiver. Always verify function with the weapon cleared and in a safe direction.
My FRT-15 isn’t resetting reliably. What should I check?
Start with the fundamentals of your rifle’s cycle. Ensure it is properly lubricated. Check that your gas block is aligned and secure. Experiment with buffer weight and spring combinations—often a heavier buffer (H2/H3) can improve the recoil impulse for this system. The goal is a robust, consistent rearward movement of the bolt carrier group.
Does this come with all necessary springs and pins?
Yes. The FRT-15 is a complete fire control group. It includes the proprietary hammer, trigger, disconnector, and all associated springs and pins required for installation into a mil-spec lower receiver.
What is your return policy?
Miamishooterssupply offers a 30-day return period for unused items in original packaging. Due to the nature of firearm components, once installed or used, returns cannot be accepted for resale. Please inspect the component thoroughly upon receipt.
