Render only the second point of a Line Renderer?

I'm using a line renderer as a laser sight on a gun, but rather than a laser sight, I'd like it to just be a red dot. I have the second point of the line rednerer set at the hit point of a raycast through script, so is it possible to only render that point of the line renderer, rather than the whole line?

Here's the script if it helps:

 public class LaserSight : MonoBehaviour {
     
     private LineRenderer lr;
     
     // Use this for initialization
     void Start () {
         
         lr = GetComponent<LineRenderer>();
         
     }
     
     // Update is called once per frame
     void Update () {
         
         RaycastHit hit;
         
         if(Physics.Raycast(transform.position, transform.forward, out hit)){
             
             if(hit.collider){
                 
                 lr.SetPosition(1, new Vector3(0,0,hit.distance));
                 
             }
             
             else{
                 
                 lr.SetPosition(1, new Vector3(0,0,5000));
             }
             
         }
         
     }
 }
