Machine gun trigger with select fire

A trigger assembly for a firearm having an operational rod configured to reciprocate longitudinally along a bore axis of the firearm, the trigger assembly comprising:

• a trigger rotatable between a resting position and a pulled position;
• a disconnector pivotable between a first position in which a part of the disconnector is in a path of the operational rod and a second position in which the part of the disconnector is out of the path of the operational rod;
• a sear pivotable between an engaged position and a disengaged position, the sear biased toward the engaged position, wherein in the engaged position a part of the sear is positioned to engage the operational rod;
• a sear link pivotably connected to the trigger, wherein pulling the trigger moves the sear link into contact with the sear to pivot the sear towards the disengaged position, and wherein the sear link is spaced from the sear when the trigger is in the resting position;
• and
• a selector operable between a safe position, a fully automatic fire position, and a semiautomatic fire position.
