Mouse.Button1Down:Connect(function()
	if script.Parent.Variables.Ammo.Value > 0 and Down == false and Equipped == true and EquipDebounce == false and Tool.Variables.Debounce.Value == false and ReloadCooldown == false and Humanoid.Health > 0 and Tool.Variables.FireDebounce.Value == false and Deb2 == true and Deb3 == true then
		Tool.Variables.FireDebounce.Value = true
		Tool.MuzzleEffect.FlashFX.Enabled = true
		local mousePosition = Mouse.Hit.Position
		Fire:Play()
		wait(0.02)
		script.Parent.Events.FireEvent:FireServer(mousePosition)
		wait(0.06)

		local Shell = game.ReplicatedStorage.Holes.Shell:Clone()
		Shell.Parent = workspace.Casings
		Shell.CFrame = script.Parent.Eject.CFrame
		Shell.AssemblyLinearVelocity = Vector3.new(9,25,0)

		game.Debris:AddItem(Shell, 17)
		
		local TweenService = game:GetService("TweenService")
		local time = 0.1
		local tween2 = TweenService:Create(Player.PlayerGui.GunGUI.Screen, TweenInfo.new(time), {ImageTransparency = 0.35})
		tween2:Play()
		tween2.Completed:Connect(function()

			local time = 1
			local tween3 = TweenService:Create(Player.PlayerGui.GunGUI.Screen, TweenInfo.new(time), {ImageTransparency = 1})
			tween3:Play()

Instead of using a value to toggle debounce, make it a variable in your script.

Also, there could also be a desync between the client and server if you have stuff in seperate scripts.
