Designed to accelerate follow-up shots while remaining within legal parameters, the innovative Forced Reset system resets the trigger after each shot, enabling faster, more consistent firing.

Perfect for competitive shooting, tactical training, or maximizing your HK roller-delayed firearm’s potential.
Crafted from high-quality materials, including 7075 anodized aluminum and heat-treated 4140, the FRT-RD3™ (AMBI) is built to endure heavy use. This robust construction ensures reliability and longevity, allowing you to push your roller locked firearm to its limits with confidence.
The FRT-RD3™ (AMBI) is specifically engineered to operate with the factory semi-automatic bolt carrier used in the HK MP5, MP5K, SP5, and SP5K roller-delayed pattern firearms. For that reason, the FRT-RD3™ (AMBI) is compatible with models containing factory full-auto carrier denial blocks in the receiver with no modifications needed to the firearm. The FRT-RD3™ (AMBI) provides simple plug and play installation. Please note: The FRT-RD3™ (AMBI) is also compatible with all full-auto bolt carrier groups but one is not required.
The HK AMBI grip frame is identified by the modern Pictogram markings (often called the “Navy” style). Instead of letters, it uses bullet icons: a white slashed bullet for Safe, a single red bullet for Semi, and (if applicable) multiple red bullets in a box for Burst or Auto. This configuration uses levers on both sides of the frame. The indicator mark is located on the forward-facing radius of the selector axle rather than a pointing tail.
The FRT-RD3™ (AMBI) is ideal for shooters seeking speed and precision. The FRT-RD3™ (AMBI) was designed from the ground up as a specific HK, roller-delayed trigger. Specific geometry ensures correct, safe timing and function for the roller-delayed platform with no possibility of firearm damage. The FRT-RD3™ (AMBI) provides a clean, crisp 2-stage trigger pull. By mechanically resetting the trigger after each shot, then locking the trigger from being pulled until the BCG returns to battery, this system allows for faster follow-up shots without needing advanced techniques. The forced reset mechanism ensures the trigger returns to the non-firing position after each round, requiring the shooter to pull the trigger again, offering full control over each shot.
If you’re looking to boost your HK roller-delayed firearm’s performance, the FRT-RD3 (AMBI) Forced Reset Trigger is the ultimate upgrade. With its rapid-fire capability, versatile fitment, and seamless compatibility with the HK MP5/SP5 and similar roller-delayed firearm platforms, this trigger provides a superior shooting experience for competition, tactical use, or range drills. Unlock the full potential of your HK MP5, MP5K, SP5, or SP5K with the FRT-RD3™ (AMBI).”
