How can I make the gun rotate and shoot like lost control and shooting all around ?

The shooting part I will make later. Now I'm trying to make the rotations part.

The first t$$anonymous$$ng I did is to rotate the gun barrel and t$$anonymous$$s is working fine. The next t$$anonymous$$ng I want to do is to rotate the gun body 360 degrees randomly so when the gun will shoot it will shoot randomly all around like lost control.

T$$anonymous$$s is a screenshot of the gun barrel :

And the gun body :

By rotating the gun body 360 degrees randomly I want to create a lost control effect so it will shoot all around $$anonymous$$tting randomly.

The script is attached to the top parent Drone :

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Rotate : MonoBehaviour
 {
     public Transform[] wings;
     public Transform[] propellers;
     public Transform gunBarrel;
     public Transform gunBody;
     public float propellersSpinSpeed = 50;
     public float wingsSpinSpeed = 50;
     public float gunBarrelSpeed = 50;
 
     private float angle = 360.0f;
 
     // Start is called before the first frame update
     void Start()
     {
 
     }
 
     // Update is called once per frame
     void Update()
     {
         for (int i = 0; i < propellers.Length; i++)
         {
             propellers[i].Rotate(0, propellersSpinSpeed * Time.deltaTime, 0);
         }
 
         for (int i = 0; i < wings.Length; i++)
         {
             wings[i].Rotate(0, wingsSpinSpeed * Time.deltaTime, 0);
         }
 
         gunBarrel.Rotate(0, 30 * gunBarrelSpeed * Time.deltaTime, 0);
 
         gunBody.Rotate(Vector3.zero, angle * Time.deltaTime / 1.0f);
     }
 }

I tried to do :

 gunBody.Rotate(Vector3.zero, angle * Time.deltaTime / 1.0f);

But it does not$$anonymous$$ng not rotating it 360 degrees and I didn't use yet the Random. The gun barrel keep rotating but the lost control shooting all around is not working yet not sure how to do it.
