Share a variable between scrips, between children

Question

I have a player, who has a ammo variable, from an attached script. T$$anonymous$$s allows for the ammo to increase through collision with ammo packs.

 public class Ammo : MonoBehaviour
 {
     public float ammo = 10f;
     public float amount = 5f;

 void Start()
 {

 }

 private void OnControllerColliderHit(ControllerColliderHit $$anonymous$$t)
 {
 if ($$anonymous$$t.gameObject.CompareTag("AmmoPack"))
     {
         Destroy($$anonymous$$t.gameObject);
         Debug.Log("Hit");
         ammo += (amount/2);
     }
 }

}

I have a gun game object with two different scripts to control how the gun works, each have a separate ammo system.

 {

 public float ammo = 10f;
 public float damage = 10f;
 public float range = 100f;
 public float fireRate = 4f;
 public float nextTimeToFire = 0f;
 public ParticleSystem muzzleFlash;
 public GameObject impact;

 public Camera fpsCam;
 // Start is called before the first frame update
 void Start()
 {
     
 }

 // Update is called once per frame
 void Update()
 {
     if(Input.GetButtonDown("Fire1") && Time.time >= nextTimeToFire)
     {
         if (ammo > 0)
         {
             nextTimeToFire = Time.time + 1f/fireRate;
             shoot();
             ammo = ammo -= 1;
         }
     }
     
 }

^ T$$anonymous$$s is the same on both scripts (One called Gun, the other called Conversion)

What I want is for the ammo to be shared between the two scripts on my gun (Gun and Conversion), w$$anonymous$$le also being shared with my Ammo script on my Player game object.

Hierarchy:

↓Player (Has the ammo script on it)
↓Main Camera
↓Small Gun (Has the Gun and Conversion scripts on it)

You can get the ammo script, store it in a variable, and then access any of its public variables/methods.

For example you could do somet$$anonymous$$ng like t$$anonymous$$s in your gun script:

 //Variable to store the ammo script
 Ammo ammoScript;
 
 void Start()
  {
 //Find the ammo script in the parent object and store it
      ammoScript = GetComponentInParent<Ammo>();
  }
  
  void Update()
  {
 //Subtract one from the ammo value of the Ammo script.
        ammoScript.ammo -= 1;
 }
