Gun Scope Not Centered

I'm having the most annoying issue with my gun scope. When I Use it, It's not centered. Here is a picture of what happends:

I Understand I Have to have my sights lined up to the centre of the gun, But when I Do that, This is what happends:

My Gun is really low to the ground. This is my current Scope script:

 var cameraObject : GameObject;
 @HideInInspector
 var targetXRotation : float;
 @HideInInspector
 var targetYRotation : float;
 @HideInInspector
 var targetXRotationV : float;
 @HideInInspector
 var targetYRotationV : float;

 var rotateSpeed : float = 0.3;

 var holdHeight : float = -0.5;
 var holdSide : float = 0.5;
 var racioHipHold : float = 1;
 var hipToAimSpeed : float = 0.1;
 @HideInInspector
 var racioHipHoldV : float;

 function Update () 
 {
    if (Input.GetButton("Fire2"))
        racioHipHold = Mathf.SmoothDamp(racioHipHold, 0, racioHipHoldV, hipToAimSpeed);
    if (Input.GetButton("Fire2") == false)
        racioHipHold = Mathf.SmoothDamp(racioHipHold, 1, racioHipHoldV, hipToAimSpeed);
  

    transform.position = cameraObject.transform.position + (Quaternion.Euler(0,targetYRotation,0) * Vector3(holdSide * racioHipHold, holdHeight * racioHipHold, 0));
 
    targetXRotation = Mathf.SmoothDamp( targetXRotation, cameraObject.GetComponent(FPSMouseLook).xRotation, targetXRotationV, rotateSpeed);
    targetYRotation = Mathf.SmoothDamp( targetYRotation, cameraObject.GetComponent(FPSMouseLook).yRotation, targetYRotationV, rotateSpeed);
 
    transform.rotation = Quaternion.Euler(targetXRotation, targetYRotation, 0);
  }

If you know how to fix this, Please leave a comment below! Thanks in Advance!
