Why is my projectile's rotation sideways?

I'm trying to fire my laser projectile but it's rotation is sideways when i shoot it, i changed the rotation in blender but that did no better, it was still sideways! If there is something i have to do to my model or script please tell me. Thanks!

 using UnityEngine;
 using System.Collections;
 
 public class Shooting : MonoBehaviour
 {
     public Rigidbody projectile;
     public float speed = 20;
 
     // Update is called once per frame
     void Update ()
     {
         if (Input.GetButtonDown("Fire1"))
         {
             Rigidbody instantiatedProjectile = Instantiate(projectile,transform.position,transform.rotation)as Rigidbody;
             instantiatedProjectile.velocity = transform.forward * speed;
             instantiatedProjectile.transform.forward = transform.forward;
         }
     }
 }
