Bullet trying to set object that doesn't even exist

My bullet is trying to set the game object “gun” to a game object that doesn’t even exist in my assets what so ever. 78869-inspector.jpg

Shotgun2 doesn’t even exist in my scene!

It comes up with the error

NullReferenceException: Object reference not set to an instance of an object
BulletScript.Awake () (at Assets/BulletScript.js:23)
UnityEngine.Object:Instantiate(Object, Vector3, Quaternion)

When I double click on the error it sends me here. Highlighting “if(gun.GetComponent(Gun).aiming == true)”

Bullet Script:

#pragma strict

var bulletHole : GameObject;
var floatInFrontOfWall : float = 0.001;
var maxDist : float = 10000000000;
var Enemy : GameObject;
var maxDamage : float = 15;
var minDamage : float = 5;

var gun : GameObject;
var blood : GameObject;

//Accuracy
var minAimAccuracy : float;
var maxAimAccuracy : float;
var minHipAccuracy : float;
var maxHipAccuracy : float;

function Awake () {
    
    gun = GameObject.FindWithTag("Gun");

    if(gun.GetComponent(Gun).aiming == true)
    {
        transform.rotation.eulerAngles.y += Random.Range(minAimAccuracy, maxAimAccuracy);
        transform.rotation.eulerAngles.x += Random.Range(minAimAccuracy, maxAimAccuracy);
    }   
    if(gun.GetComponent(Gun).aiming == false)
    {
        transform.rotation.eulerAngles.y += Random.Range(minHipAccuracy, maxHipAccuracy);
        transform.rotation.eulerAngles.x += Random.Range(minHipAccuracy, maxHipAccuracy);
    }   
}

function Update () {
    var hit : RaycastHit;
    var damage = Random.Range(minDamage, maxDamage);
    if(Physics.Raycast(transform.position, transform.forward,hit, maxDist))
    {
        if(bulletHole && hit.transform.tag == "Terrain")  
            Instantiate(bulletHole, hit.point +(hit.normal * floatInFrontOfWall),Quaternion.LookRotation(hit.normal));
        if(hit.transform.tag == "Enemy")    
        {
            Enemy  = hit.collider.gameObject;

        }
        if(Enemy)
            Enemy.GetComponent(EnemyHealth).currentHealth -= damage;
    }
    Destroy(gameObject);
}

I have other objects in my scene with the tag “Gun” but it doesn’t seem to want to use those
Please help!

Unless that first photo was taken during runtime your Gun object is already set to “Shotgun2(Clone)” set that to none and it should hunt the scene for the object with the tag “Gun”
