Why does my gun fire all guns in the server when fired?

Hi! I made a gun script, local script, and remote event to communicate between the local and server script. When two or more players have there guns out at the same time and I click to fire the gun all the players with their guns out will fire their guns. Here is the local script:

local player = game.Players.LocalPlayer
local character = player.CharacterAdded:Wait()
local mouse = player:GetMouse()
local tool = script.Parent

tool.Equipped:Connect(function()
	tool.Activated:Connect(function()
		local mouse_location = mouse.Hit.Position
		local bullet_ray = Ray.new(tool.Main.CFrame.Position,(mouse_location - tool.Main.CFrame.Position).unit * 300)
		local part,position = workspace:FindPartOnRay(bullet_ray,character,false,false)
		game.ReplicatedStorage.Lee.fired:FireServer(character,mouse_location,position,part)
	end)
end)

Here is the server script:

local tool = script.Parent
local enabled = false
UIS = game:GetService("UserInputService")

game.ReplicatedStorage.Lee.fired.OnServerEvent:Connect(function(player,character,mouse_location,position,part)
	if tool.Ammo.Value > 0 then
		if not enabled then
			enabled = true
			tool.Ammo.Value = tool.Ammo.Value - 1
			
			local bullet = Instance.new("Part",game.Workspace)
			bullet.BrickColor = BrickColor.new("New Yeller")
			bullet.Transparency = 0
			bullet.Material = Enum.Material.SmoothPlastic
			bullet.Anchored = true
			bullet.Locked = true
			bullet.CanCollide = false
			
			local distance = (tool.Main.CFrame.Position - position).Magnitude
			bullet.Size = Vector3.new(0.2,0.2,distance)
			bullet.CFrame = CFrame.new(tool.Main.CFrame.Position,position) * CFrame.new(0,0,-distance/2)
			
			game:GetService("Debris"):AddItem(bullet,0.1)
			tool.GunSounds.GunFired:Play()
			
			if part ~= nil then
				local humanoid = part.Parent:FindFirstChild("Humanoid")
				if humanoid ~= nil then
					humanoid:TakeDamage(50)
					if humanoid.Health <= 0 then
						player.PlayerGui.killGui.killFrame.killLabel.Text = "You killed " .. tostring(humanoid.Parent.Name) .. "!"
						wait(3)
						player.PlayerGui.killGui.killFrame.killLabel.Text = ""
					end
				end
			end
			tool.Main.smoke.Enabled = true
			tool.Main.fire.Enabled = true
			tool.Main.light.Enabled = true
			wait(0.2)
			tool.Main.smoke.Enabled = false
			tool.Main.fire.Enabled = false
			tool.Main.light.Enabled = false
			tool.GunSounds.GunChamber:Play()
			local animation = character:WaitForChild("Humanoid"):LoadAnimation(tool.prime)
			animation:Play()
			wait(2)
			enabled = false
		end
	else
		tool.GunSounds.OutOfAmmoFired:Play()
	end
end)

Thanks!

Problem fixed! All I had to do was delete:

local tool = script.Parent

in the server script then add the variable "tool" in the local script to the remote event!
