FRT-RD3 (Ambi) Two-Stage (3-Position) Forced Reset Trigger for the HK MP5, MP5K, SP5 & SP5K The FRT-RD3 (Ambi) Two-Stage (3-Position) Forced Reset Trigger for the HK MP5, MP5K, SP5 & SP5K represents a precision-engineered upgrade from Rare Breed. This trigger system is designed to deliver a distinct shooting experience through a forced-reset mechanism that re-engages the hammer immediately after each shot, allowing the shooter to maintain a rapid cycling rhythm without modifying the firearm’s internal operating system. Built specifically for the HK roller-delayed blowback platform, this unit is a direct drop-in replacement for factory trigger packs in MP5, MP5K, SP5, and SP5K models. Overview Rare Breed has developed the FRT-RD3 to provide a genuine two-stage trigger pull with a third selectable position. This is not a binary trigger or a conversion device; it is a mechanically complete trigger pack that uses a forced-reset sear geometry. The ambidextrous selector allows the shooter to choose between safe, semi-automatic, and the forced-reset mode. Each position is tactile and audible, with no modifications required to the host firearm. The FRT-RD3 (Ambi) Two-Stage (3-Position) Forced Reset Trigger for the HK MP5, MP5K, SP5 & SP5K is manufactured from heat-treated steel and billet aluminum components, with a Mil-Spec hardcoat anodized finish for durability.
