The Rare Breed FRT-MR3 is a forced reset trigger designed specifically for the HK MR556 and MR223 rifle platforms. It uses the same patented mechanical reset principle as the FRT-15 — the bolt carrier's forward stroke resets the trigger — adapted for the HK roller-delayed operating system.

The FRT-MR3 is compatible with the 3-position selector configuration and ships ready for installation in standard MR556/MR223 trigger groups.
