How do I make the Arms of an R6 body follow mouse?

I've made this code and it points to mouse it just is inside of the body for some reason?

repeat wait() until game.Players.LocalPlayer.Character

local body = game.Players.LocalPlayer.Character
local left_arm = body["Left Arm"]
local right_arm = body["Right Arm"]
local mouse = game.Players.LocalPlayer:GetMouse()


--

leftDown = false
rightDown = false


mouse.Button1Down:Connect(function()
	leftDown = true
end)

mouse.Button1Up:Connect(function()
	leftDown = false
end)

mouse.Button2Down:Connect(function()
	rightDown = true
end)

mouse.Button2Up:Connect(function()
	rightDown = false
end)

local leftArmWeld = Instance.new("Weld")
leftArmWeld.Parent = body
leftArmWeld.Part0 = body.Torso
leftArmWeld.Part1 = left_arm
leftArmWeld.Name = "LeftArmWeld"


local rightArmWeld = Instance.new("Weld")
rightArmWeld.Parent = body
rightArmWeld.Part0 = body.Torso
rightArmWeld.Part1 = right_arm
leftArmWeld.Name = "RightArmWeld"

local armoffset_left = body.Torso.CFrame:Inverse() * body["Left Arm"].CFrame
local armoffset_right = body.Torso.CFrame:Inverse() * body["Right Arm"].CFrame


mouse.Move:Connect(function()
	local x,y,z = CFrame.new(body["Left Arm"].Position,mouse.Hit.Position):ToEulerAnglesXYZ()
	local x1,y1,z1 = CFrame.new(body["Right Arm"].Position,mouse.Hit.Position):ToEulerAnglesXYZ()

	if leftDown then
		leftArmWeld.C0 = armoffset_left * CFrame.fromEulerAnglesXYZ(x,y,z) * CFrame.fromEulerAnglesXYZ(math.rad(90),0,0)
	else
		leftArmWeld.C0 = armoffset_left
	end
	

end)

Well, There doesn't seem to be any problem with the CFrame Coding. The lines I have read do not seem correct though, Maybe rearrange a bit of the start and kind of to the 25% mark. Or if you want r15 You can try finding my post.

Look's good from my perspective, so I won't say anything about it.

You can use your opinion.
