Rare Breed Triggers FRT-15C3™ Forced Reset Trigger

Price: $451.00

Let’s cut through the noise and talk about what the Rare Breed FRT-15C3 actually is and what it does for your AR-15. This isn’t magic, it’s smart mechanical engineering. We’ll give you the straight facts so you know exactly what you’re getting.

How a Forced Reset Trigger Works: The Practical Explanation

You need to understand the basics of your standard AR-15 trigger first. In a normal semi-auto, the trigger and the sear (the part that holds the hammer) are connected by a disconnector. You pull the trigger, it fires. When the bolt cycles back, it catches on that disconnector. You must release the trigger to reset that disconnector before you can fire again. That’s the “reset” you feel.

A Forced Reset Trigger changes that equation. The FRT-15C3 uses the energy from the cycling bolt carrier group to physically push the trigger forward and reset it for you, automatically. You don’t release pressure; the gun does it. The result? If you maintain steady rearward pressure on the trigger, it will fire, be forced to reset, and fire again the instant the bolt is back in battery. One trigger pull still equals one round fired, but the reset is mechanical and instantaneous.

FRT-15C3™ Features & Specifications

This is a complete, drop-in trigger pack. You get the trigger, hammer, disconnector, a 3-position ambidextrous safety selector, and anti-walk pins. It’s built here in the USA from 7075 aluminum and heat-treated S7 tool steel. This is a duty-grade component, not a range toy.

• 3-Position Selector: Safe, Semi-Auto, and FRT. The ambi safety is included.
• Semi-Auto Mode: A clean, two-stage trigger. About 2.5 lbs of take-up, a crisp wall, then a 2 lb break. Total around 4.5 lbs. It’s a very good combat-style trigger on its own.
• FRT Mode: A single-stage, heavier pull weight of 5-5.5 lbs throughout the travel. This is the forced reset function.
• Installation: Drops into a standard MIL-SPEC AR-15 lower. The anti-walk pins ensure nothing shifts during use. Installation is straightforward if you know how to assemble a lower receiver.

What This Means on the Range

In FRT mode, you achieve a drastically increased rate of controlled fire through mechanical consistency, not finger speed. The trigger’s reset is faster and more positive than any human finger movement. This allows for rapid, controlled pairs or strings of fire while maintaining a solid, consistent grip. It’s a significant advantage in competitive shooting drills and enhances tactical training muscle memory for follow-up shots. The key word is control; you are not at the mercy of a binary or uncontrolled system. You stop applying rearward pressure, firing stops immediately.

Critical Compatibility & Installation Notes (Read This)

This isn’t a “plug and play and forget” part. For reliable function, your rifle needs to be set up correctly. We will not sell you this if you aren’t prepared to handle these details.

• Bolt Carrier Group (BCG): You MUST use a full-auto profile (M16) bolt carrier. A semi-auto only carrier will not work. The auto-sear trip shelf on the full-auto carrier is what engages the forced reset mechanism.
• Buffer System: Your rifle needs to be properly gassed and buffered. We strongly recommend an H2 or H3 heavy buffer, or an A5 buffer system. A standard carbine buffer will often cause malfunctions due to excessive bolt speed. This is non-negotiable for reliability.
• Lower Receiver Compatibility: Fits standard MIL-SPEC lowers. It will NOT fit Colt-style lowers or any lower with an integrated sear block (often called a “shelf” or “block”). Check your lower receiver before purchasing.
• Ammunition: Use full-power, brass-cased ammunition. Underpowered steel-case or pistol-caliber carbine ammo may not provide enough energy to cycle the action reliably with the FRT mechanism.

Who This Trigger Is For

This trigger is for the experienced shooter who understands their AR-15 platform inside and out. It’s for the competitor looking for a mechanical edge in timed events. It’s for the serious enthusiast who values innovative engineering and wants to explore the functional limits of their rifle with a system that demands proper setup and maintenance. It is a precision tool for skilled users.

Legal Disclaimer & Final Point

The FRT-15C3 is designed as a forced reset trigger. It fires one round per function of the trigger. The trigger must be pulled rearward for each shot. It is the user’s responsibility to understand and comply with all federal, state, and local laws regarding firearm components. This product is protected by U.S. Patents, including Nos. 12,038,247 and 12,578,159.

Bottom line: The Rare Breed FRT-15C3 is a sophisticated, robust, and uniquely functional trigger system. It requires knowledge to install and tune but offers a shooting experience unlike any other traditional trigger. If you have the know-how and a properly configured rifle, it’s a serious upgrade.

Manufactured and Assembled in the USA.
