1. In a firearm; an operating rod disposed for reciprocation between a breech closed position and a recoil position in response to the cyclic rate of the firearm; sear means spring biased into a holding position for retaining said operating rod in a cocked position; trigger means pivotable into a firing position to release said sear from said holding position; counter cam means having a cam surface rotatably mounted in said firearm in a position to be rotated by said operating rod; a trigger bar mounted in said firearm for movement into one of three preselected positions, said preselected positions including an automatic position, a semi-automatic position, and a controlled burst fire position; selector means for moving said trigger bar into said preselected positions; said trigger bar in said semi-automatic position being out of contact with said sear means and engageable with said counter cam to prevent said counter cam from being rotated whereby a single round is fired with each pivot of said trigger means, in said automatic position being engageable with said counter cam to prevent rotation thereof and operable to be moved by said trigger means upon pivoting thereof to a position to cam said sear and prevent said sear from retaining said operating rod in a cocked position whereby rounds are continuously fired as long as said trigger means remains pivoted, in said controlled burst fire position being engageable with said cam surface of said counter cam to be moved upon rotation of said counter cam into a position to cam said sear and prevent said sear from retaining said operating rod in a cocked position whereby a predetermined number of rounds are fired upon pivoting said trigger means.
