How do I make this gun shoot four lasers?

So, I got a cool futuristic gun mesh and I wanted to make it actually shoot. So I got a hyperlaser model that shoots three laser beams. I copied some parts from it into the gun, and it works perfectly. However, the futuristic gun has four holes that it shoots out of, but the script only shoots three. What parts do I need to change/add in order for it to shoot four lasers? There are two local scripts, one is called "MouseIcon" and the other one is "ToolScript", which has a sound in it (if that means anything) The mouseicon script:

local MOUSE_ICON = 'rbxasset://textures/GunCursor.png'
local RELOADING_ICON = 'rbxasset://textures/GunWaitCursor.png'

local Tool = script.Parent

local Mouse = nil

local function UpdateIcon()
	if Mouse then
		Mouse.Icon = Tool.Enabled and MOUSE_ICON or RELOADING_ICON
	end
end

local function OnEquipped(mouse)
	Mouse = mouse
	UpdateIcon()
end

local function OnChanged(property)
	if property == 'Enabled' then
		UpdateIcon()
	end
end

Tool.Equipped:connect(OnEquipped)
Tool.Changed:connect(OnChanged)

The ToolScript script:

local SHOT_SPEED = 100

--------------------
--| Script Logic |--
--------------------

BaseShot = Instance.new('Part')
BaseShot.Name = 'Effect'
BaseShot.FormFactor = Enum.FormFactor.Custom
BaseShot.Size = Vector3.new(0.2, 0.2, 3)
BaseShot.CanCollide = false
BaseShot.BrickColor = BrickColor.new('Toothpaste')
SelectionBoxify(BaseShot)
Light(BaseShot)
HitFadeSound:Clone().Parent = BaseShot

Tool.Equipped:connect(OnEquipped)
Tool.Unequipped:connect(OnUnequipped)
Tool.Activated:connect(OnActivated)

Or do I have to edit something else other than the scripts?

Thanks, zlotis
