The part for the laser won't extend for the gaster blaster, It just moves (?)

Hello!

I am making a script where when you click with a certain tool equipped It summons a gaster blaster that face depending on where you are and then It shoots a laser, the problem Is the laser, the laser simply refuses for It to extend, however I want the laser to extend on one face which Is where the blaster Is facing

What I mean Is that I want the laser to extend like this:

[0------]

Not like:

[---0---]

But the laser refuses to extend, just simply moving a bit

Script:

local Tool = script.Parent

Tool.RemoteEvent.OnServerEvent:Connect(function()
    local GastGun = game:GetService("ReplicatedStorage").VisualEffectMesh["Gast Gun"]:Clone()
    game:GetService("Debris"):AddItem(GastGun,5)
    GastGun.Parent = game.Workspace
    GastGun.Position = Tool.Parent.Torso.Position
    GastGun.Orientation = Tool.Parent.Torso.Orientation
    GastGun.Transparency = 1
    local TweenProperties = {
        CFrame = GastGun.CFrame + (GastGun.CFrame.LookVector*5),
        Transparency = 0
    }
    local Tweeninfo = TweenInfo.new(
        1,
        Enum.EasingStyle.Bounce,
        Enum.EasingDirection.Out,
        0,
        false,
        0
    )
    local Tween = game:GetService("TweenService"):Create(GastGun,Tweeninfo,TweenProperties)
    Tween:Play()
    Tool.Parent.Sounds.OhGodNo:Play()
    wait(0.469)
    local DeltaSize = 9
    local LASER = game:GetService("ReplicatedStorage").VisualEffectMesh["Lazer"]:Clone()
    game:GetService("Debris"):AddItem(LASER,5)
    Tool.Parent.Sounds.Death:Play()
    LASER.Parent = game.Workspace
    LASER.Position = GastGun.Position
    LASER.Orientation = GastGun.Orientation
    local LaserProperties = {
        Size = LASER.Size + Vector3.FromAxis(Enum.Axis.X)*DeltaSize,
        Position = LASER.Position + Vector3.FromNormalId(Enum.NormalId.Front)*DeltaSize/2
    }
    local Tweeninfo = TweenInfo.new(
        1,
        Enum.EasingStyle.Sine,
        Enum.EasingDirection.In,
        0,
        false,
        0
    )
    local Tween = game:GetService("TweenService"):Create(LASER,Tweeninfo,TweenProperties)
    Tween:Play()
    LASER.Touched:Connect(function(hit)
        local humanoid = hit.Parent:WaitForChild("Humanoid")
        if humanoid ~= Tool.Parent.Humanoid then
            humanoid:TakeDamage(math.random(10,50))
            wait(0.1)
        end
    end)
end)
