Let’s talk about the Rare Breed FRT-15. This isn’t just another trigger. It’s a specific piece of engineering that changes the mechanical operation of your AR-15. If you understand how a standard trigger works—you pull, it fires, you release, it resets—then you know the reset is the limiting factor for speed. The FRT-15 eliminates that limit.

Here’s the straight talk: This is a forced reset trigger (FRT). The recoil energy from your fired round does the work. As your bolt carrier group goes back into battery, it physically pushes the trigger back to the reset position for you. This means the trigger is ready for the next pull the instant the gun is back in battery. The rate of fire is determined by how fast you can pull the trigger and how fast your rifle cycles. It’s a mechanical advantage, pure and simple.

What You Get in the Kit:

• The FRT-15 Trigger Assembly: The complete hammer, trigger, and disconnector system with the forced reset mechanism.
• Three-Position Safety Selector: This is crucial. Position 1 is Safe. Position 2 is Standard Semi-Auto—functions like a normal trigger. Position 3 is Forced Reset Mode. You select the function.
• Anti-Walk Pins: High-quality pins included. With the unique forces at play, you don’t want pins walking. These keep everything locked in tight.
• All Necessary Springs and Hardware: Everything you need for the install is in the box.

Build & Materials (The Important Stuff):

We’ve seen the inside of these. The critical components are cut via wire EDM (Electrical Discharge Machining). This isn’t stamped or MIM (Metal Injection Molded) metal. EDM cutting provides extreme precision and clean, hardened edges that stand up to wear. The housing is 7075-T6 aluminum—the same stuff used for premium upper and lower receivers. The finish is a black nitride QPQ. This isn’t paint; it’s a surface treatment that increases hardness and corrosion resistance. They built this to last.

Installation & Function:

Installation Note: If you’ve installed a drop-in trigger before, you can handle this. It drops into a standard AR-15 lower receiver. The only non-standard part is ensuring the safety selector is correctly oriented for the three positions. The instructions are clear. Use the anti-walk pins. As always, if you’re not comfortable, take it to a competent gunsmith.

How It Feels: In Semi-Auto mode (Selector Position 2), it’s a clean, crisp single-stage pull. When you switch to Forced Reset mode (Selector Position 3), the feel changes. The reset is immediate and positive—you can feel it. It requires a deliberate, full pull and a full release for each shot. This isn’t a “bump fire” stock; it’s a controlled, mechanical rapid fire where you are in command of every shot. Practice and proper technique are required to run it smoothly and safely.

Who This Is For:

This trigger is for the experienced shooter who wants to explore the mechanical limits of their platform. It’s for the individual who values understanding the engineering behind their equipment. It’s built for demanding use where reliability under speed is non-negotiable. If you’re looking for a range toy that also represents a fascinating piece of firearm engineering, this is it.
