I cant get this to do anything to the enemy

[fierce hearth]

private void RaycastForEnemy()
    {
        RaycastHit hit;
        if (Physics.Raycast(transform.parent.position, transform.parent.forward, out hit, 1 << LayerMask.NameToLayer("Enemy")))
        {
            try
            {
                Debug.Log("Hit an Enemy!");
                Rigidbody rb = hit.transform.GetComponent<Rigidbody>();
                rb.constraints = RigidbodyConstraints.None;
                rb.AddForce(transform.parent.transform.forward * 500);
            }
            catch
            {

            }
        }
    }
