Gun Aiming Script Almost Perfect

I have come pretty far with this one script, and it's almost exactly as I want it, however there's one problem.
The script is a sniper rifle scope aiming script and I have the camera field of view lerp into 20 from 100 very smoothly, I love it, but the gun stays floating where it spawns. I have the gun as a child to the main camera which is a child of the first person controller, and I have the script on the gun. When I first start, the gun stays in place, but it smoothly turns to face where I am facing. However, it will not follow my character, and when I press right click, it disappears. I think that the problem is because the locations of Vector3 aren't relative to the character controller, but I don't know how to make it so. Please help a n00b. ^^
HERE IS THE SCRIPT

public var smooth : float;

private var newPosition : Vector3;
private var newFov : float;


function Awake ()
{
newPosition = transform.position;
newFov = Camera.main.fieldOfView;
}

function Update ()
{
PositionChanging();
FovChanging();
}


function PositionChanging ()
{
var positionA : Vector3 = new Vector3(0.5014648, -1.076523, 0.1868896);
var positionB : Vector3 = new Vector3(-0.01593018, -0.7554626, -0.2791138);

if(Input.GetButtonDown("Fire2"))
newPosition = positionB;
if(Input.GetButtonUp ("Fire2"))
newPosition = positionA;

transform.position = Vector3.Lerp(transform.position, newPosition, smooth * Time.deltaTime);

}


function FovChanging ()
{
var fovA : float = 100;
var fovB : float = 20;

if (Input.GetButtonDown("Fire2"))
newFov = fovB;
if (Input.GetButtonUp("Fire2"))
newFov = fovA;

camera.main.fieldOfView = Mathf.Lerp(Camera.main.fieldOfView, newFov, smooth * Time.deltaTime);
}

 

Why would you think it would do ANYTHING differently? You are changing the objects GLOBAL position to one of 2 points, meaning that object will ONLY be in one of those two points regardless of relation to its parents. If you want it to move like a normal child but still need those points as offsets make them adjust the LOCAL position and they will move accordingly.

 

How would I make it local? transform.localPosition?

 

Yeh. though if your weapon starts where you want it relative to the player/camera you are gonna want to return your local position to Vector3.zero and not the other.
