Problem with firing laser in direction of camera

I'm working on a FPS assignment for school and need to create a gun that shoots lasers. I have a two scripts; one for shooting the laser and one for moving it. The problem I'm having is that the laser only ever moves in the positive Z direction. Here's my code for the update functions in the Shooting and LaserMove classes. I've tried Googling my question but haven't had much luck.

Also, I'm using the First Person Controller from the Character Controller package in Unity.

Any and all help towards making the laser shoot in the direction of the camera would be greatly appreciated.

Shoot:

public GameObject laser = null; public Transform gunPos;

void Update () { if(Input.GetMouseButtonDown(0)) { Instantiate(laser, gunPos.position, Quaternion.identity); } }

LaserMove:

public GameObject laser = null; public Transform gunPos;

void Update () {
transform.localPosition += transform.forward*speed*Time.deltaTime;

 if(laser.transform.position.x >= 40 || laser.transform.position.x <= -40)
 {
     Destroy(gameObject);
 }
 else if(laser.transform.position.y >= 40 || laser.transform.position.y <= -40)
 {
     Destroy(gameObject);
 }
 else if(laser.transform.position.z >= 40 || laser.transform.position.z <= -40)
 {
     Destroy(gameObject);
 }

}
