Question Weapon Sway with FPS arms

I am looking to add weapon sway to my Set up. I watched a couple of tutorials and found a simple one that works. Code below:

Code (CSharp):

1. {
2.     public float smooth;
3.     public float swayAmount;
4.  
5.     // Update is called once per frame
6.     void Update()
7.     {
8.        float mouseX = -Input.GetAxisRaw("Mouse X") * swayAmount;
9.        float mouseY = Input.GetAxisRaw("Mouse Y") * swayAmount;
10.  
11.        Quaternion rotationX = Quaternion.AngleAxis(mouseY, Vector3.right);
12.        Quaternion rotationY = Quaternion.AngleAxis(-mouseX, Vector3.up);
13.  
14.        Quaternion targetRotation = rotationX * rotationY;
15.  
16.        transform.localRotation = Quaternion.Slerp(transform.localRotation, targetRotation, smooth * Time.deltaTime);
17.     }

The thing is, whenever attached to anything except the gun, the object gets turned around. I currently have it attached to just the guns, and it looks good. However my arms do not move with the sway. I tried adding it to the arms, and it forces the arms to do a 180 (facing behind me). I attached a screen shot of the hierarchy that shows the order of where everything is stored.
Right now I am just testing this out on the AKM. When picking up the weapon, it becomes a child object of the AKMHoldLocation. I think that it has something to do with the fact that I cannot get the arms to face the same direction as the camera unless I rotate it 180 Degrees. so it starts with that rotation on it. Would love feedback on A.) if there is a better way to set the hierarchy up, and B.) what is causing the arms to turn 180 when the script is activated(turns on when weapon is picked up). I am still shaky with camera rotation and things related, so anything helps. Thank you. Mouse Look Script Below:

Code (CSharp):

1. {
2.     public float mouseSensitivity = 100f;
3.  
4.     public Transform playerBody;
5.  
6.     float xRotation = 0f;
7.  
8.     // Start is called before the first frame update
9.     void Start()
10.     {
11.         Cursor.lockState = CursorLockMode.Locked;
12.    
13.     }
14.  
15.     // Update is called once per frame
16.     void Update()
17.     {
18.        
19.        
20.             float mouseX = Input.GetAxis ("Mouse X") * mouseSensitivity * Time.deltaTime;
21.         float mouseY = Input.GetAxis ("Mouse Y") * mouseSensitivity * Time.deltaTime;
22.  
23.         xRotation -= mouseY;
24.         xRotation = Mathf.Clamp(xRotation, -90f, 90f);
25.  
26.         transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
27.  
28.  
29.         playerBody.Rotate(Vector3.up * mouseX);
30.  
31.     }

 

Try attaching it to the parent of the gun
