Enhanced Reset Trigger – Rare Breed FRT 15 E3

The Rare Breed FRT-15 E3 represents a significant evolution in forced-reset trigger technology. This enhanced reset trigger – Rare Breed FRT 15 E3 is engineered for shooters who demand reliable, high-speed cyclic function without the complexity of full-automatic systems. Built from billet 4140 steel and tested over thousands of rounds, this trigger delivers a consistent, repeatable forced-reset action that resets the trigger shoe forward under spring tension as the bolt cycles. The result is a rapid, controlled firing sequence that remains compliant with ATF guidelines as a semi-automatic component when installed in a legal configuration.

Overview

The Rare Breed FRT-15 E3 is a drop-in trigger system designed for AR-15 pattern rifles chambered in 5.56 NATO. It operates on a mechanical forced-reset principle: the trigger shoe is physically pushed forward by the hammer during the carrier cycle, allowing the shooter to maintain trigger pressure while the mechanism resets automatically. This enhanced reset trigger – Rare Breed FRT 15 E3 uses a three-position selector (safe, semi, forced-reset) and requires no modification to the lower receiver. The E3 revision improves the sear engagement geometry and adds a hardened steel trip bar for increased durability over the original FRT-15 model. Each unit is assembled and function-tested at the Rare Breed facility in Florida.

Features & Specs

The FRT-15 E3 is precision-machined from certified 4140 steel with a QPQ corrosion-resistant finish. The trigger pull weight is factory set at approximately 5.5 pounds with a crisp break and minimal overtravel. The forced-reset mechanism engages only when the selector is in the FRT position, allowing standard semi-automatic operation in the safe and semi positions. Key specifications include:

• Three-position selector: Safe / Semi-Automatic / Forced-Reset (FRT) – compliant with ATF classification as a semi-automatic trigger component.
• Drop-in installation: No pins, springs, or jigs required. Fits standard mil-spec lower receivers with no modifications to the fire control pocket.
• Material: 4140 steel hammer, trigger, and disconnector. Trip bar is hardened to Rockwell 48-52 HRC for wear resistance.

Additional manufacturing details include a phosphate-coated hammer and a nitrided trigger shoe. The E3 revision incorporates a redesigned disconnector spring that reduces trigger slap and improves reset consistency across varying temperatures. Each unit ships with a stainless steel anti-walk trigger pin set to prevent lateral movement under high-vibration firing schedules. This enhanced reset trigger – Rare Breed FRT 15 E3 is compatible with all standard AR-15 bolt carrier groups and buffer systems.

• Reset cycle: Mechanical forced-reset via hammer-trip bar interface. No springs or gas systems involved in the reset function.
• Operating temperature range: -20°F to 160°F. Tested with full-auto rated bolts and heavy buffers.
• Weight: 3.4 ounces (complete trigger assembly including pins and selector).

Who It’s For

This trigger is intended for competitive shooters, firearms enthusiasts, and professional trainers who require a high-speed shooting capability within a legal semi-automatic platform. The forced-reset action allows the shooter to maintain a consistent grip and sight picture while achieving rapid follow-up shots. It is not a binary trigger, nor does it convert the firearm to full-automatic function. The enhanced reset trigger – Rare Breed FRT 15 E3 is best suited for experienced shooters who understand trigger discipline and the mechanical operation of forced-reset systems. It is not recommended for new shooters or for use in hunting applications where single-shot precision is required. The trigger is compatible with all standard AR-15 pattern rifles that accept drop-in trigger cassettes, including those with ambidextrous safeties and aftermarket fire control groups.
