Overview

The FRT-MR3™ Single-Stage (3-Position) Forced Reset Trigger for the HK MR223 & HK MR556 represents a precision-engineered upgrade from Rare Breed, designed specifically for the HK MR223 and MR556 platform. This drop-in trigger assembly introduces a three-position selector that delivers a distinct forced-reset cycling mechanism, allowing the shooter to manually reset the trigger forward after each shot without relying on standard spring return. The FRT-MR3™ Single-Stage (3-Position) Forced Reset Trigger for the HK MR223 & HK MR556 is built for operators and enthusiasts who demand a tactile, controlled shooting experience. Rare Breed has optimized this unit to mate directly with the MR223/MR556 lower receiver, ensuring no permanent modifications are required.

Features & Specs

• Three-position selector: safe, semi-automatic, and forced-reset mode. The third position enables the trigger to reset only after the shooter fully releases and re-engages the trigger shoe.
• Single-stage design with a consistent 4.5-5.5 lb pull weight, providing a crisp break and a short, defined reset travel.
• Drop-in installation: no gunsmithing needed. Includes all necessary pins and springs for direct replacement of the factory trigger group.
• Manufactured by Rare Breed, a trusted name in aftermarket trigger systems, and categorized under triggers for the MR223/MR556 platform.
• Constructed from hardened steel and aircraft-grade aluminum with a corrosion-resistant coating, rated for sustained use in demanding conditions.

Who It’s For

The FRT-MR3™ Single-Stage (3-Position) Forced Reset Trigger for the HK MR223 & HK MR556 is intended for experienced shooters, competitive marksmen, and professionals who train with the MR223 or MR556 rifle. This trigger suits those who want to increase their cyclic rate through manual reset technique without converting to a fully automatic system. It is also appropriate for collectors and enthusiasts who appreciate Rare Breed’s engineering and want a dedicated upgrade for their HK platform. This product is not designed for casual plinking; it requires the user to understand the forced-reset method and to practice safe, controlled manipulation of the trigger.
