US12442608 - Machine gun trigger with select fire

A trigger assembly includes a selector operable between a safe position, a semiautomatic fire position, and an automatic fire position. In one example, the assembly includes a trigger rotatable between a resting position and a pulled position, a disconnector pivotable between a first position where it is in the path of the operational rod, and a second position where it is out of the path of the operational rod. A sear is pivotable between an engaged position and a disengaged position and is biased to the engaged position where it is positioned in the path of the operational rod. A sear link is pivotably connected to the trigger, such that pulling the trigger moves the sear link into contact with the sear to pivot the sear towards the disengaged position. The sear link is spaced from the sear when the trigger is in the resting position.
