Unity Aim Down Sights Animation While Shooting

I am making an FPS Game and am using an animation for the shooting. I have made it so i can aim in by changing the Guns position. I have used the same animation for shooting, but have positioned it the same place as i would be scoped so it does the shooting animation while i am scoped. The problem is with my code, if i let go of my right arrow key(aim) while the animation for the shooting while aiming, it just stopped the animation and doesn't go back to original position.

 using UnityEngine;
 using System.Collections;
 
 public class aimDownScope : MonoBehaviour {
 
 
     public Vector3 aimDownSight;
     public Vector3 hipFire;
 
     // Update is called once per frame
     void Update()
     {
         if (Input.GetMouseButton(1))
         {
             transform.localPosition = Vector3.Slerp(transform.localPosition, aimDownSight, 15 * Time.deltaTime); //Aim In
         }
         if (Input.GetMouseButtonDown(0))
         {
             GetComponent<Animation>().CrossFade("fire"); //Play shooting animation for Gun
         }
         if (Input.GetMouseButton(1) && (Input.GetMouseButton(0)))
         {
             GetComponent<Animation>().CrossFade("fireaim"); //If aiming and press the shoot button, play shooting animation while ads
         }
         else if (Input.GetMouseButtonUp(1))
         {
             transform.localPosition = hipFire; // if you let go of right click (to aim) go back to origional position
         }
     }
 }
