ActionScript 3.0 :: Double Barrel Rotating Turret?

i am trying to make a "double-barrel" firing cannon in AS3..below is a crappy drawing of what im trying to acheive...im having trouble making the two bullets come out where they should (1 on the left barrel, 1 on the right barrel). prior to this, i already successfully created a standard "one-barrel" turret that rotates depending on the mouse location and fires 1 bullet per shot.. what i'm trying to do now is (like i said above) to create a double-barrel turret that would fire 2 bullets per shot (1 on the gun1 and 1 on gun2)..below is the code i used for the single-barrel turret: on the timeline:

ActionScript Code:
stage.addEventListener(Event.ENTER_FRAME, followMouse);
stage.addEventListener(KeyboardEvent.KEY_DOWN, fireBullet);
var radians:Number;

[code]....
