Rotate weapon with the crossair and cursor lock

So i have 3 scripts the first one is

 public class PlayerCrosshairs : MonoBehaviour
 {
     public Transform anchor;
     public float maxMoveRadius;
     public float sensitivity = 1f;
     Vector3 position = Vector2.zero;
 
     private void Update()
     {
         CrossairLocation();
     }
 
     public void CrossairLocation()
     {
         Vector3 moveDelta = new Vector3(Input.GetAxis("Mouse X"), Input.GetAxis("Mouse Y"), 0);
         position = Vector3.ClampMagnitude(position + moveDelta * sensitivity, maxMoveRadius);
         transform.position = anchor.position + position;
     }
 }

I assign in the inspector the "crossair" the max range and the anchor and it is working fine.

my second script is

 public class CursorManager : MonoBehaviour
 {
     public static bool isLocked;
 
     private void Start()
     {
         Cursor.lockState = CursorLockMode.Locked;
         Cursor.visible = false;
     }
 
     public void CursorLocked(bool isLocked)
     {
         if (isLocked)
         {
             Cursor.visible = false;
             Cursor.lockState = CursorLockMode.Locked;
         }
         if (!isLocked)
         {
             Cursor.visible = true;
             Cursor.lockState = CursorLockMode.None;
         }
     }
 }

Who is also working fine, it lock the cursor so i only see the crossair in the first script. the probleme is in the next script

i want the weapon of my 2d sprite to also follow the crossair (a gun) but i cannot seem to find how to use the crossair.rotation to follow the weapon.rotation (i have try several thing and none of them is working

 public class PlayerWeaponManager : MonoBehaviour
 {
     PlayerCrosshairs thePlayerCrosshairs;
     private float rotate;
 
     private void Start()
     {
         rotate = transform.position.z;
     }
     // Update is called once per frame
     void Update()
     {
       // rotate = transform.position.z;
       // rotate  = thePlayerCrosshairs.CrosshairLocation();
     }
 }

sorry for my bad english im french.
