How to modify variables from second script.

Hi! I want make reloading weapon and i need to modify variables from weapon script. I dont know how to do t$$anonymous$$s because GetComponent does not allow t$$anonymous$$s. Script in weapon:

 public class StatystykiBroni : MonoBehaviour
 {
 
     //-----------------------------------------Ammo \/
     public int magazynki = 6;
     public int ammoInMags = 30;
     public int ammoInGun = 0;
     public int komora = 0;
 
 }

Void in Script from FpsController:

 void Ammo()
     {
         StatystykiBroni wpn = gameObject.GetComponentInC$$anonymous$$ldren<StatystykiBroni>();
         if (Input.GetButtonDown("Reload") && (wpn.ammoInGun < wpn.ammoInMags) && wpn.magazynki > 0)
         {
             if (wpn.ammoInGun != 0)
             {
                 wpn.komora = 1;
             }
             wpn.magazynki--;
             wpn.ammoInGun = wpn.ammoInMags + wpn.komora;
             wpn.komora = 0;
         }
     }
 
 }

Thanks for answers!
