How do I make my arm point to the mouse's position?

Hello guys, I am working on a shooter game and I need my right arm to face the direction of the mouse. The script I have works, but when I face backward, the arm seems to go slightly back as well.

Is there any way to fix this or limit how far the arm turns?

script:

local armOffset = char.Torso.CFrame:Inverse() * (char["Right Arm"].CFrame * CFrame.new(0,0.5,-0.5))

local armWeld = Instance.new("Weld")
armWeld.Part0 = char.Torso
armWeld.Part1 = char["Right Arm"]
armWeld.Parent = char


RunService.Heartbeat:Connect(function()
	if debounce == true then
		armWeld.Parent = char.Torso
	local cframe = CFrame.new(char.Torso.Position, mouse.Hit.Position) * CFrame.Angles(math.pi/2, 0, 0)
		armWeld.C0 = armOffset * char.Torso.CFrame:toObjectSpace(cframe)
	else
		armWeld.Parent = game.Lighting
		armWeld.C0 = char.Torso["Right Shoulder"].C0 * CFrame.new(0,0,0)
	end
end)

(the gun in the video is for testing)
Thank you.

Trying to make the hand look at mouse but acts weird on some axis

Use the new CFrame.lookAt instead of the deprecated CFrame.new(pos,lookAt).

You can use the look vector of the torso and compare it to the lookAtMouse CFrame using vector3:Dot(vector3), and then decide whether or not it’s facing the front/back of the torso. Here’s a helpful guide if you need one.
