Multiplayer frendly weapon select screen

I have a scene where you can select weapons and atatchments. the current way how i switch the weapons is using DontDestroyOnLoad and SetActive and . How can I make it so that it works in multiplayer(the player gets spawned by the network manager) this is the weapon switching script

 using UnityEngine;
 using System.Collections;
 
 public class NewWeaponSwitch : MonoBehaviour {
 
     public GameObject gun1;
     public GameObject gun2;
     public GameObject gadget3;
     public GameObject gadget4;
     public bool tempReload = false;
     //public GameObject gun;
     public Weapon weaponScript;
 
     // Use this for initialization
     public void Start(){
         //weaponScript = gun1.GetComponent<Weapon>();
         //tempReload = weaponScript.reloading;;
         //tempReload = weaponScript.reloading;
     }
 
     // Update is called once per frame
 public    void Update () {
         if(gun1.activeSelf ==true){
             weaponScript = gun1.GetComponent<Weapon>();
             tempReload = weaponScript.reloading;
         }
         if(gun2.activeSelf ==true){
             weaponScript = gun2.GetComponent<Weapon>();
             tempReload = weaponScript.reloading;
         }
         if(gadget3.activeSelf ==true){
             weaponScript = gadget3.GetComponent<Weapon>();
             tempReload = weaponScript.reloading;
         }
         if(gadget4.activeSelf ==true){
             weaponScript = gadget3.GetComponent<Weapon>();
             tempReload = weaponScript.reloading;
         }
     if(tempReload == false){
         if (Input.GetButtonDown("SwitchWeapons")){
             switchWeapons();
         }
 
         if(Input.GetButtonDown("Gadget3")){
 
             gun2.gameObject.SetActive(false);
             gun1.gameObject.SetActive(false);
             gadget3.gameObject.SetActive(true);
             gadget4.gameObject.SetActive(false);
 
                 
 
         }
         if(Input.GetButtonDown("Gadget4")){
             gun2.gameObject.SetActive(false);
             gun1.gameObject.SetActive(false);
             gadget3.gameObject.SetActive(false);
             gadget4.gameObject.SetActive(true);
 
 
         }
     }
     }
 
     public    void switchWeapons(){
         if(gun1.activeSelf == true){
             gun2.gameObject.SetActive(true);
             gun1.gameObject.SetActive(false);
             gadget3.gameObject.SetActive(false);
             gadget4.gameObject.SetActive(false);
             //Debug.Log("weapon1 active");
         }
         else if(gun2.activeSelf == true){
             gun1.gameObject.SetActive(true);
             gun2.gameObject.SetActive(false);
             gadget3.gameObject.SetActive(false);
             gadget4.gameObject.SetActive(false);
         //    Debug.Log("weapon2 active");
         }
         else {
 
             gun1.gameObject.SetActive(true);
             gun2.gameObject.SetActive(false);
             gadget3.gameObject.SetActive(false);
             gadget4.gameObject.SetActive(false);
 
         }
 
         
     }
 
 
 
 }
  and the current weapon select script
 using UnityEngine;
 using System.Collections;
 
 public class ARSelectScript : MonoBehaviour {
 
     public GameObject ARSelectCanvas;
     public GameObject ARHeavyCanvas;
     public GameObject ARHeavyAttachmentsCanvas;
 
     public GameObject ArHeavyPrefab;
     public GameObject player;
     public GameObject arm;
     public GameObject HUD;
     public Canvas HUDCanvas;
 
 //    public GameObject PrimaryWeapon;
 
     public string WeaponSelectScreen;
 
     void Start () {
         ARSelectCanvas.SetActive(true);
         ARHeavyCanvas.SetActive(false);
         ARHeavyAttachmentsCanvas.SetActive(false);
         DontDestroyOnLoad(player.gameObject);
         DontDestroyOnLoad(HUD.gameObject);
         Time.timeScale= 0f;
         HUDCanvas = HUD.GetComponent<Canvas>();
         HUDCanvas.enabled = false;
     }
     public void HeavyARMenu(){
         ARSelectCanvas.SetActive(false);
         ARHeavyCanvas.SetActive(true);
         ARHeavyAttachmentsCanvas.SetActive(false);
     }
     public void ARSelectMenu(){
         ARSelectCanvas.SetActive(true);
         ARHeavyCanvas.SetActive(false);
         ARHeavyAttachmentsCanvas.SetActive(false);
     }
     public void ARHeavyAttatchmentsMenu(){
         ARSelectCanvas.SetActive(false);
         ARHeavyCanvas.SetActive(false);
         ARHeavyAttachmentsCanvas.SetActive(true);
     }
     public void BackToWeaponSelectScreen(){
         Application.LoadLevel(WeaponSelectScreen);
     }
     public void SaveArHeavy(){
     //    ArHeavyPrefab.SetActive(true);
         NewWeaponSwitch SwitchScript = arm.GetComponent<NewWeaponSwitch>();
         SwitchScript.gun1 = ArHeavyPrefab;
         Application.LoadLevel(WeaponSelectScreen);
     }
 
 }
