How can I make this work with Filtering Enabled?

So I am working with the roblox raycast script on the wiki and ive been able to make a working gun however in multiplayer the Beam/bullet cant be seen by anyone but the player and damage is dealt locally so when shot players dont actually take damage and die.

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

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

        game:GetService("Debris"):AddItem(beam, 0.05)

                wait(.09)   

        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(7.5)
                script.Parent.Hit:Play()
