Engineered from the ground up for the HK roller-delayed platform, this MP5 FRT trigger pack brings the legendary performance of Rare Breed Triggers to your HK MP5, MP5K, SP5, and SP5K. At Buy Triggers, we are proud to offer this official, 100% American-made trigger system that answers the demand for the best MP5 FRT on the market. Whether you own a full-size SP5 or a compact MP5K, the FRT-RD3™ delivers the forced reset experience you have been waiting for, with drop-in installation and duty-grade construction that sets a new standard for the platform.

MP5 FRT 3 Position Functionality and Design

The MP5 FRT 3 position selector is a standout feature of the FRT-RD3™ (AMBI) system. This true 3-position forced reset trigger offers:

Safe Position: Mechanical safety engaged with white slashed bullet indicator
Semi Position: Standard semi-automatic operation with single red bullet
FRT Position: Forced reset mode activated, allowing dramatically faster follow-up shots

Each trigger pull in FRT mode fires one round while the innovative forced reset mechanism mechanically returns the trigger to the non-firing position after every shot. The system then locks the trigger from being pulled until the bolt carrier group returns to full battery, ensuring correct, safe timing for the roller-delayed platform with no possibility of firearm damage. This MP5 FRT provides a clean, crisp 2-stage trigger pull that enhances both precision and speed.

Compatibility and Installation for HK Platforms

The FRT-RD3™ (AMBI) is specifically engineered to operate with factory semi-automatic bolt carriers used in HK MP5, MP5K, SP5, and SP5K roller-delayed pattern firearms. This MP5 FRT trigger pack is compatible with models containing factory full-auto carrier denial blocks in the receiver—no modifications to your firearm are needed. The kit includes:

1 x FRT-RD3™ Trigger
1 x Ambidextrous Safety Selector (HK AMBI style with Pictogram markings)
1 x 1/16 Allen Key
1 x 2mm Allen Key

The HK AMBI grip frame compatibility means this Rare Breed MP5 FRT works with the modern “Navy” style grip frames featuring bullet icon Pictogram markings. Installation is simple plug-and-play, with the ambidextrous safety selector designed for easy installation in HK AMBI type grip frames.

Built for Duty: Construction and Durability

Crafted from high-quality materials, the FRT-RD3™ (AMBI) features 7075 anodized aluminum components and heat-treated 4140 steel internals. This MP5 FRT is built to endure heavy use, ensuring reliability and longevity that allows you to push your roller-locked firearm to its limits with complete confidence. The specific geometry engineered into this MP5 FRT 3 position system ensures correct, safe timing for the roller-delayed platform, with no possibility of firearm damage even under sustained rapid fire.
