ABSTRACT:
A crossbow trigger whose features include only a unitary leaf spring, without the help of coiled springs, whose four end portions clamp a crossbow bolt on a crossbow stock, bias the crossbow's sight, bias the crossbow's finger lever, and prevent accidental disengagement of the crossbow's trigger safety. A stop plate is provided on the crossbow trigger's sear to automatically provide a proper space between the rear end of a crossbow bolt and the portion of the bowstring held by the cocked trigger.
