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)

Some CFrame Magic

 local Goal = {
        Size = Part.Size + Vector3.new(5, 0, 0),
        CFrame = Part.CFrame * CFrame.new(5/2, 0, 0)
}
