ArgumentOutOfRangeException - Generic List - Javascript

Hi, I am making a Sidescroller-Shooter Game and im at the point, where i want to add multiple Weapons to my player, that I can switch through. So I used a Generic list to this, which has the variables, that need to be assigned in it.

 public class Weapons
 {
 
      public var name : String = "Weapon";
      public var firemode : fMode = fMode.semi;
      public var firerate : float = 0.1f;
      
     
      public var model : Transform;
      public var raystart : Transform;
      public var muzzle : GameObject;
      public var muzzlelight : Light;
 }

I Better show you the full script, so you can see it better.

 #pragma strict
 import System.Collections.Generic;
     
     private var muzzletime : float = 0.1;
     public var CurrentWeapon : Weapons;    //Here i got the List defined
     public var weapons : List.<Weapons>;   //CurrentWeapon is for the Weapon in hand
     weapons = new List.<Weapons>();
 
     
 
     // Use this for initialization
     function Start () {
     weapons.Capacity = 2;
         Debug.Log("möglich" + weapons.Capacity + ", drin" + weapons.Count);
         CurrentWeapon.muzzlelight.light.enabled = true;
         CurrentWeapon = weapons[0]; //here i choose a list entry || It says the Mistake is here
     
     }
     
     // Update is called once per frame
     function Update () {
     
         Muzzlecontroll();
     }
     
     function Shoot (i : int) {
     
     if(Input.GetMouseButtonDown(i) && CurrentWeapon.firemode == fMode.semi){
 
         if(Physics.Raycast(CurrentWeapon.raystart.position, CurrentWeapon.raystart.TransformDirection(Vector3.forward), 20)){
             Debug.DrawRay(CurrentWeapon.raystart.position,CurrentWeapon.raystart.TransformDirection(Vector3.forward) * 10,Color.red);
             Debug.Log ("Something was hit");
             
         }
         CurrentWeapon.model.animation.Play("Recoil");
         CurrentWeapon.muzzle.renderer.enabled = true;
         muzzletime = 0.1;
         CurrentWeapon.muzzlelight.light.enabled = true;
     }
 
         if(muzzletime < 0){
         CurrentWeapon.muzzle.renderer.enabled = false;
         }
     }
     
 function Muzzlecontroll () {
 
         if(muzzletime >= 0.0){
         muzzletime -= Time.deltaTime;
         }
             if(muzzletime < 0){
         CurrentWeapon.muzzle.renderer.enabled = false;
         CurrentWeapon.muzzlelight.light.enabled = false;
         }
     
 
 }
 
 public enum fMode
 {
     rocketlauncher,
     auto,
     semi,
     bolt
 }
 
 public class Weapons //<--- The weapon class
 {
 
      public var name : String = "Weapon";
      public var firemode : fMode = fMode.semi;
      public var firerate : float = 0.1f;
      
     
      public var model : Transform;
      public var raystart : Transform;
      public var muzzle : GameObject;
      public var muzzlelight : Light;
 }

Then i fill in the variables in the editor. But if i then want to start the game, it sets my size of the list again to 0, and says: "ArguementOutOfRangeException: Argument is out of Range"

And says the Mistake is there`CurrentWeapon = weapons[0];`

Hopy someone could help me and that my Question is readable. I really need some help.
