The FRT-MR3 brings Rare Breed's forced reset trigger to the Heckler & Koch MR223 / MR556 platform. It is a semi-automatic trigger — one round per function — with the same forced-reset feel FRT owners expect, engineered for the HK fire-control geometry rather than a standard AR-15.
Genuine Rare Breed Triggers®. Because HK platforms differ from a mil-spec AR-15, confirm your model before ordering; our team can help. This is the curved-face MR3; a flat version is also offered.
