How can i make my light beam attack always start in front of the character?

Sorry for the rough scripts, im fairly new, but what im trying to do is make a cylinder shaped object start in front of you and quickly expand outwards. my problem is that i cant figure out how to get it to go in front of you, and its always going across 1 of the axis.

Code for the local script that triggers the attack

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local UserInputService = game:GetService("UserInputService")
local plr = game.Players.LocalPlayer
local Char = plr.Character or plr.CharacterAdded:Wait()
local Remote = ReplicatedStorage.Fired
local Mouse = plr:GetMouse()

local Debounce = true
local Key = 'R'

UserInputService.InputBegan:Connect(function(Input, IsTyping)
 if IsTyping then return end
 local KeyPressed = Input.KeyCode
 if KeyPressed == Enum.KeyCode[Key] and Debounce and Char then
  Debounce = false
  Remote:FireServer(Mouse.Hit)
  wait(1)
  Debounce = true
 end
end)

Code for the attack itself

game.ReplicatedStorage.Fired.OnServerEvent:Connect(function(Player, Debounce)
    local Character = Player.Character or Player.CharacterAdded:wait()
    Debounce = true
    local LightBeam = Instance.new("Part")
    LightBeam.Name = "LightBeam"
    LightBeam.Size = Vector3.new(3,3,3)
    LightBeam.Shape = Enum.PartType.Cylinder
    LightBeam.Material = Enum.Material.Neon
    LightBeam.BrickColor = BrickColor.new("Cool yellow")
    LightBeam.CanCollide = false
    LightBeam.Parent = Character
    LightBeam.CFrame = Character.Torso.CFrame*CFrame.new(0,1,0)
    LightBeam.Anchored = true
    wait(.2)
    LightBeam.Size = Vector3.new(104,3,104)
    wait(2)
    LightBeam:Destroy()
end)

the game is set up to only use r6 models btw
