How would I force player wait for bullet firing?

I'd like the player to have to wait to be able to fire again for .2 seconds, that's how long the animation is, how would I do that?

local tool = script.Parent
local player = game:GetService("Players").LocalPlayer

tool.Equipped:connect(function(mouse)
    print("Tool Equipped")

    mouse.Button1Down:connect(function()
        print("Mouse pressed!")
        local ray = Ray.new(tool.BulletExit.CFrame.p,(mouse.Hit.p - tool.BulletExit.CFrame.p).unit * 300)
        local part, position = workspace:FindPartOnRay(ray, player.Character, false, true)

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

        local distance = (tool.BulletExit.CFrame.p - position).magnitude
        beam.Size = Vector3.new(0.3, 0.3, distance)
        beam.CFrame = CFrame.new(tool.BulletExit.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(15)
            end
        end
    end)
end)
