FRT-MR3™ Single-Stage (3-Position) Forced Reset Trigger for the HK MR223 & HK MR556

Overview

The FRT-MR3™ Single-Stage (3-Position) Forced Reset Trigger for the HK MR223 & HK MR556 represents a precision-engineered drop-in trigger system developed by Rare Breed. Designed specifically for the HK MR223 and HK MR556 platform, this trigger utilizes forced reset technology to deliver a unique trigger cycling mechanism. The FRT-MR3™ offers three distinct selector positions, providing the operator with a single-stage trigger pull that resets via the bolt carrier group’s forward motion. This trigger system is machined from hardened steel components and finished with a corrosion-resistant coating suitable for high-use environments. Rare Breed has engineered this unit to maintain factory-spec hammer and sear engagement tolerances while incorporating the forced reset function that distinguishes it from standard single-stage triggers.
