Why won't the reload system work?

So i am trying to make a reload system for a gun im making, but when ever i reach 30, the mag falls out, but a new one doesn't spawn back in. Why? Here is the script.

local tool = script.Parent
local player = game:GetService("Players").LocalPlayer
local sound = script.Parent.Handle.shot
local shooting = false
local ammo = 30
local equipped = false
local mouseConnection
tool.Equipped:Connect(function(mouse)
equipped = true
	mouseConnection = mouse.Button1Down:Connect(function()
		shooting = true
		while shooting and equipped do
			ammo = ammo - 1
			print(ammo)
			if ammo < 1 then
				for i, v in pairs(script.Parent.Muzzel:GetChildren()) do
					v.Destroy()
				end
				tool.Muzzel:Clone()
				local Muzzel = tool.Muzzel:Clone()
				Muzzel.Parent = tool
				Muzzel.Name = "Muzzel"
				Muzzel.Position = game.Muzzel.Position
			end
		print("Mouse pressed!")
		sound:Play()
		local ray = Ray.new(tool.Muzzel.CFrame.p, (mouse.Hit.p - tool.Muzzel.CFrame.p).unit * 300)
		local part, position = workspace:FindPartOnRay(ray, player.Character, false, true)


		
		local beam = Instance.new("Part", workspace)
		beam.BrickColor = BrickColor.new("Neon orange")
		beam.FormFactor = "Custom"
		beam.Material = "Neon"
		beam.Transparency = 0.25
		beam.Anchored = true
		beam.Locked = true
		beam.CanCollide = false
		
		
	
	
		


		local distance = (tool.Muzzel.CFrame.p - position).magnitude
		beam.Size = Vector3.new(0.3, 0.3, distance)
		beam.CFrame = CFrame.new(tool.Muzzel.CFrame.p, position) * CFrame.new(0, 0, -distance / 2)

		game:GetService("Debris"):AddItem(beam, 0.1)

		if part then
			local humanoid = part.Parent:FindFirstChild("Humanoid")

			if not humanoid then
				humanoid = part.Parent.Parent:FindFirstChild("Humanoid")
			end

			if humanoid then
				humanoid:TakeDamage(30)
			end
			end
			mouse.Button1Up:Connect(function()

				shooting = false

			end)
			wait(0.1)
			end
	end)
end)

tool.Unequipped:Connect(function()

	equipped = false

	mouseConnection:Disconnect()

end)
