Use the line renderer for simulate shotgun shoot

Hello, i’m trying to use the line renderer for draw various lines from shotgun to a end point, for this i use a for loop with a Raycast2D, the Raycast works fine, but i only see a one line renderer when i shoot, this is the code what i using:

if (weapon == Weapon.Shotgun) {
			for (int i = 0; i < 4; i++) {
				RaycastHit2D shotgunHit;
				Quaternion spreadAngle = Quaternion.Euler (0.0f, 0.0f, 4f * i);
				shotgunHit = Physics2D.Raycast (firePosition, spreadAngle * rayDir, distance, whatToHit);

				if (Input.GetButtonDown ("Fire1") && fireRate == 0.0f) {
					line.enabled = true;
					line.SetPosition (0, firePoint.position);
					if (shotgunHit) {
						if (shotgunHit.collider.tag == "Enemy") {   
							line.SetPosition (1, shotgunHit.point);
						}
					} else {
						line.SetPosition (1, firePoint.position + (spreadAngle * rayDir * distance));
					}
				}

The objective is draw a 4 line renderer between the shotgun and the end of the raycast using the for loop.

Regards and thanks.

I think line renderer can only draw a single line with different positions, so to solve my problem I created a GameObject containing a line renderer, assigning the start and end of the line renderer in a script, then instantiate this GameObject using the for-loop to create the required GameObjects.
