trying to make cross bow in unity

trying to turn my gun script into a cross bow script.

ATM the xbow is fired and the dmg is applyed before my arrow gets to the target

any help is always appeciated

using UnityEngine;
using System.Collections;

public class Bow : MonoBehaviour {
	
	public Transform projectile;
	public int range = 100;
	public float fireRate = 1f;
	public float force = 10f;
	public float damage = 5f;
	public int bulletsPerClip = 40;
	public int clips = 20;
	public float reloadTime = .5f;
	public ParticleEmitter hitParticles;
	public Renderer muzzleFlash;
	
	
	public LayerMask removeWaypoints; //stop from hitting waypoint
	
	private int bulletsLeft = 0;
	private float nextFireTime = 0f;
	private float m_LastFramesShot = -1f;
	
	// Use this for initialization
	void Start () {
		hitParticles = GetComponentInChildren<ParticleEmitter>();
		
		//particles emit only when hit something
		if(hitParticles)
		{
			hitParticles.emit = false;
		}
		bulletsLeft = bulletsPerClip;
	}
	
	// Update is called once per frame
	void LateUpdate () 
	{
		if(muzzleFlash)
		{
			//we shoot this frame enable muzzleFlash
			if(m_LastFramesShot == Time.frameCount)
			{
				muzzleFlash.transform.localRotation = 
					Quaternion.AngleAxis(Random.Range(0, 359), Vector3.forward);
				muzzleFlash.enabled = true;
				
				if(audio)
				{
					if(!audio.isPlaying)
						audio.Play();
					audio.loop = true;
					
				}
			}
			else    //we didn't diable muzzleFlash
			{
				muzzleFlash.enabled = false;
				enabled = false;
				
				//play sound
				if(audio)
				{
					audio.loop = false;
				}
			}
		}
	}

	public void Fire()
	{
		if(bulletsLeft == 0)
			return;
		
		if(Time.time - fireRate > nextFireTime)
			nextFireTime = Time.time - Time.deltaTime;
		
		while(nextFireTime < Time.time  bulletsLeft != 0)
		{
			FireOneShot();
			nextFireTime += fireRate;
		}
	}

		//did we hit anything
		if(Physics.Raycast(transform.position, direction, out hit, range, removeWaypoints))
		{
			projectile.transform.position = hit.point;
			//apply force to rigidbody we hit
			if(hit.rigidbody)
				hit.rigidbody.AddForceAtPosition(force * direction, hit.point);
		
			//spawn particles out of place we hit
			if(hitParticles)
			{
				hitParticles.transform.position = hit.point;
				hitParticles.transform.rotation =
					Quaternion.FromToRotation(Vector3.up, hit.normal);
				hitParticles.Emit();
			}
		
			//send damage message to object we hit

	}

Your current xbow is using raycasts for applying damage that’s why your target takes damage before the projectile reaches the target. Raycasts are instant so damage is applied instantly. If you want the projectile to damage the target you’ll have to remove the raycast in your bow script and add the damage dealing parts to the projectile script.
