Visualized Bullet not showing on local script? (RAYCAST)

So I am making a gun using raycast and I'm visualizing the bullet on the clientside to prevent Bullet lag. But I came across a problem where it's not visualizing the bullet. I tried to put Cframe.LookAt but still not working. Can anyone please help me? Local script:

local laser = script.Parent
local handle = script.Parent.Handle
local startbul = handle.Attachment
local replicatedstorage = game:GetService("ReplicatedStorage")
local bullet = replicatedstorage:WaitForChild("laserbullet")
local shooting = false
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
mouse.Icon = "http://www.roblox.com/asset/?id=7046646043"
laser.Equipped:Connect(function(mouse)
    mouse.Button1Down:Connect(function()
        shooting = true
        while shooting do
            wait(0.2)
            bullet:FireServer(mouse.hit.Position, startbul)
            laser.lasersound:Play()

        mouse.Button1Up:Connect(function()
            shooting = false
        end)
            end
            end)
        end)

Server Script: (Hit Detection)

local replicatedstorage = game:GetService("ReplicatedStorage")
local bullet = replicatedstorage:WaitForChild("laserbullet")
local ServerStorage = game:GetService("ServerStorage")
local laserclient = replicatedstorage:WaitForChild("laserclient")
bullet.OnServerEvent:Connect(function(player, mospos, startbul)
    local origin = startbul.WorldPosition
    local direction = (mospos - origin).Unit
    local result = workspace:Raycast(origin, direction*200)
    if result then
        local hum = result.Instance.Parent:FindFirstChild("Humanoid")
        print(result.Instance.Parent)
        if hum then
            hum:TakeDamage(30)
        end
    end
    local intersection = result and result.Position or origin + direction*200
    local distance = (origin - intersection).Magnitude 
    for _,plr in pairs(game:GetService("Players"):GetPlayers()) do
        print("passed")
            laserclient:FireClient(plr, player.Name, intersection, distance, origin, mospos, direction , result.Position)
            print("passed")
    end
end)

Another Local script: (Visualizing the bullet)

local replicatedstorage = game:GetService("ReplicatedStorage")
local laserclient = replicatedstorage:WaitForChild("laserclient")
local ServerStorage = game:GetService("ServerStorage")
local PlayerService = game:GetService("Players")

laserclient.OnClientEvent:Connect(function(player, playyername, intersection, distance, origin, mospos, direction , pos)
    local Shooter = nil
    for _, Client in pairs(PlayerService:GetPlayers()) do
        print('passed')
    if Client.Name ~= playyername then
            Shooter = Client
            print("passed")
        break
    end
end

if Shooter then
    -- Find that player's character and gun muzzle. Might have to use WaitForChild.
    local Character = Shooter.Character
    local Muzzle = Character:WaitForChild("laser")
        local bullet_clone = replicatedstorage:WaitForChild("Bullet"):Clone()
bullet_clone.Size = Vector3.new(1, 1, distance)
bullet_clone.CFrame = CFrame.new(origin, pos)*CFrame.new(0, 0, -distance/2)-- This Problem
    bullet_clone.Parent = game.Workspace
        game.Debris:AddItem(bullet_clone, 20)
        print("BULLET SPAWNING")
end
end)
