"e. When the weapon's selector is set at semiautomatic (fig 64), the trigger bar is moved from its normal off-side location in the receiver to a central position. When the trigger is pressed, the trigger action is as described in paragraph b above; however, a cam on the bottom of the rear of the bolt acts on an extension of the trigger bar and forces the trigger bar out of engagement with the sear. The sear then returns to its normal position and intercepts the bolt so that only one shot is fired. "
