Adding a spread to Rays using raycasting?

local distance = (tool.Shoot.CFrame.p - position).magnitude
beam.Size = Vector3.new(0.1, 0.1, distance)
beam.CFrame = CFrame.new(tool.Shoot.CFrame.p, position) * CFrame.new(0, 0, -distance / 2)

I'm trying to figure out how to make my ray 'spread' out, so it doesn't end up at the exact location of where the player clicked.

Trying to use raycast for a paintball game, would this be the best way to do it? Played games like Mad Paintball 2, and it looks like that uses raycast, but it has some randomness to where the bullet actually hits. I'm just using the script provided on the Roblox wiki as well.
