Does anyone have the wiki laser gun script?

It seems they have removed that page on the API which is sad because it was very helpful to a lot of people.

Luckily, I happened to have a version of that script so I tried to revert it back to its "original" state. Here you go.

	local ray = Ray.new(Handle.CFrame.p, (MouseHit.p - tool.Parent.Ship.CFrame.p).unit * 100)
	local part, position = workspace:FindPartOnRay(ray, player.Character, false, true)
	 
	local beam = Instance.new("Part", workspace)
	beam.BrickColor = BrickColor.new("Really red")
	beam.FormFactor = "Custom"
	beam.Material = "Neon"
	beam.Transparency = 0.5
	beam.Anchored = true
	beam.Locked = true
	beam.CanCollide = false

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

The damaging segment was just a condition if part exists and if the humanoid was found in the part's parent.

Hope this was of some use to you.
