The Rare Breed FRT-RD3 (AMBI) is a forced reset trigger designed from the ground up for HK roller-delayed firearms: the MP5, MP5K, SP5 and SP5K. This version is for ambidextrous (“Navy” style) grip frames, which use pictogram markings and have selector levers on both sides. It works with the factory semi-auto bolt carrier and receivers with the factory carrier block, with no changes to the firearm, and gives a two-stage pull. Every shot still requires its own separate pull of the trigger.
