Raycast Tag of Hit GameObject

I have recently been having issues with finding the tag of an object hit via Raycast. I have an object named Cube with a script "Enemy" attached to it that handles the "Damage" message. Cube also has an empty GameObject with collider parented to it with a tag called "Headshot". Currently firing any gun throws up a MissingFieldException: UnityEngine.RaycastHit.colliderS. If the whole error is necessary, it is below. My code is this:

 function SemiAutoFire () {
     var fwd = transform.TransformDirection(Vector3.forward);
     var hit : RaycastHit;
     Debug.DrawRay(transform.position, fwd, Color.red);
     if(Input.GetButtonDown ("Fire1") && Time.time > nextFire && boolet > 0 && SemiAuto == true){
         nextFire = Time.time + fireRate;
         boolet = boolet - 1;
         AutoReload();
         AudioSource.PlayClipAtPoint(gunShot, Camera.main.transform.position, 1);
         for(var i : int = 0; i < myBullets; i++){
             fwd.x += Random.Range(-accuracy, accuracy);
             fwd.y += Random.Range(-accuracy, accuracy);
             fwd.z += Random.Range(-accuracy, accuracy);
             if (Physics.Raycast(transform.position, fwd, hit, BRange)){
                 Instantiate(bulletTex[Random.Range(0,3)], hit.point, Quaternion.FromToRotation(Vector3.up, hit.normal));
                 if (hit.colliderS.compareTag("Headshot") && headshots == true){
                     print ("Nice shot, mate.");
                     hit.collider.SendMessage("Damage", damage * headshotMulti, SendMessageOptions.DontRequireReciever);
                 }
                 if (!hit.collider.compareTag("Headshot") || headshots == false){
                     print ("Nice bodyshot and/or miss, NOOB!");
                     hit.collider.SendMessage("Damage", damage, SendMessageOptions.DontRequireReciever);
                 }
     if (hit.rigidbody !=null) {
         hit.rigidbody.AddForceAtPosition(fwd * power, hit.point);
 }
 }
 }
 }
 }

Thank you for your time. This is the full error just in case:
