So I'm on my way to making a gun. But wait, the guns arms in first person do not look up with the mouse/head. What do I do? Examples are extremely helpful. Below is the weld arm script that I am using. This is my friend's weld arm and it seems a bit messy, so if I need to remake it I will. I have been wanting to know how to do this for the longest time.

Tool = script.Parent
local User
arms = false
player = game.Players.LocalPlayer
repeat wait() until player.Character
save = player.Character.Torso["Left Shoulder"]:Clone()
Tool.Equipped:connect(function()
	User = Tool.Parent
	if arms == false and player ~= nil then
		User.Torso["Right Shoulder"].C0 = CFrame.new(.6,.2,0) * CFrame.Angles(0,math.rad(90),math.rad(0))
		User.Torso["Left Shoulder"].C0 = CFrame.new(0.1,.2,.7) * CFrame.Angles(0,math.rad(-140),math.rad(-90))
		rarm = player.Character:FindFirstChild("Right Arm"):Clone()
		larm = player.Character:FindFirstChild("Left Arm"):Clone()
		rarm.Parent = game.Workspace.CurrentCamera
		larm.Parent = game.Workspace.CurrentCamera
		rarm.Name = "RA"
		larm.Name = "LA"
		rarm.formFactor = "Custom" 
		larm.formFactor = "Custom"
		larm.Material = "SmoothPlastic"
		rarm.Material = "SmoothPlastic"
		rarm.Size = Vector3.new(0.99,1.99,0.99)
		larm.Size = Vector3.new(0.99,1.99,0.99)
		local weld = Instance.new("ManualWeld",rarm)
		weld.Part0 = player.Character:FindFirstChild("Right Arm")
		weld.Part1 = rarm
		local welda = Instance.new("ManualWeld",larm)
		welda.Part0 = player.Character:FindFirstChild("Left Arm")
		welda.Part1 = larm
		local weldfix = Instance.new("ManualWeld",larm)
		weldfix.Name = "DontTouch"
		weldfix.Part0 = player.Character:FindFirstChild("Left Arm")
		weldfix.Part1 = User.Torso
		weldfix.C0 = CFrame.new(0, 0.6, 0.6)*CFrame.Angles(math.rad(-30),math.rad(0), math.rad(-90))
		arms = true
	end
end)

Tool.Unequipped:connect(function()
	-- Reset actual arms
	if arms == true then
		save.Parent = User.Torso
		User.Torso["Right Shoulder"].C0 = CFrame.new(1,.5,0) * CFrame.Angles(0,math.rad(90),0)
		User.Torso["Left Shoulder"].C0 = CFrame.new(-1,.5,0) * CFrame.Angles(0,math.rad(-90),0)
		save = User.Torso["Left Shoulder"]:Clone()
		larm:Destroy()
		rarm:Destroy()
		arms = false
	end
end)
