Bullet only goes in a single way

Im working on making my enemies but i recently noticed that my firing is off it didnt use to be like this i did upgrade the firing script to enable reloading but then i decressed the bullet speed and noticed then that my firing is wayy off so heres the code i might have done something else wrong but i tried everything i could and it still dosent work.

GUN FIRE CODE: #pragma strict

 var MaxAmmo =  1;
 var Ammo = MaxAmmo;
 var Bullet : GameObject;
 var Bullets = 25;
 var FirePoint : GameObject;   
 var ShootSound : AudioClip;
 var FireMode : String = "Semi";
 var reloading : boolean;
 var script2 : muzzleFlash;
 var script3 : Recoil;
 var NoAmmoSound : AudioClip;
 var ReloadSound : AudioClip;
 var ReloadSoundtime : int;
 
 private var timer = 0.0;
 var reloadTime = 10.0;
 
 
 function Start () {
  script3 = GetComponent(Recoil); 
  script2 = GetComponent(muzzleFlash); 
 }
 
 
 function Update () {
 
     
  if(Ammo > 0){
                        
         script3.enabled = true;              
         script2.enabled = true;
                                                                          
        if(FireMode == "Semi") 
        {   
   
           if(Input.GetMouseButtonDown(0))
           {
               FireOneBullet();
               audio.PlayOneShot(ShootSound);  // Audio for gun
           }
        }
 
      
 
           }
 
  if(Ammo == 0){               
  
        if(Input.GetMouseButtonDown(0))
           {
               audio.PlayOneShot(NoAmmoSound);  // Audio for gun
           }
  
         script3.enabled = false;              
         script2.enabled = false;                                    
  
  }
   
  
  if(Input.GetKeyDown("r"))
     {       
         ReloadSoundtime -= Time.deltaTime;
         
         
         audio.PlayOneShot(ReloadSound);
        
          Reload();
         
     }
     if(reloading) {
         
         
         if(timer<reloadTime)
         {
             timer+=Time.deltaTime;
         }
         else
             timer=0.0; 
  
         if(timer>=reloadTime)
         {
             Ammo = 30;
             timer=0.0;
             reloading = false;
         } 
     }
 
 
 }
  
   function FireOneBullet ()
 {
     var Bullet = Instantiate(Bullet, FirePoint.transform.position, transform.rotation);
     Ammo --;
 }
 
 
 function Reload ()
  {
    ReloadSoundtime ++;
     
     if(Ammo < MaxAmmo && Bullets > 0)
  { 
                
                
             reloading = true;
     }
  
  
 
  
  }

And heres the BULLET SPEED CODE:

 #pragma strict
 var BulletSpeed : int;
 
 function Start () {
     rigidbody.AddForce(transform.forward * BulletSpeed);
 }

ANY HELP WILL BE APPRICIETED THANKS GUYS!
