How would I make my gun kill the player it hits?

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.Hole.CFrame.p, (mouse.Hit.p - tool.Hole.CFrame.p).unit * 300)
		local part, position = workspace:FindPartOnRay(ray, player.Character, false, true)
		
		local beam = Instance.new("Part", workspace)
		beam.BrickColor = BrickColor.new("Bright yellow")
		beam.FormFactor = "Custom"
		beam.Material = "Neon"
		beam.Transparency = 0.1
		beam.Anchored = true
		beam.Locked = true
		beam.CanCollide = false

		
		local distance = (tool.Hole.CFrame.p - position).magnitude
		beam.Size = Vector3.new(0.3, 0.3, distance)
		beam.CFrame = CFrame.new(tool.Hole.CFrame.p, position) * CFrame.new(0, 0, -distance / 2)
		
		
		game:GetService("Debris"):AddItem(beam, 0.1)
	end)
end)

Here is my setup for the gun (picture): https://drive.google.com/file/d/1gJ1-DSUd-QKUfqNEh4LgBzLQ11cym3PK/view?usp=sharing
