how would you make a part inside a Player's Character Model visible when zoomed in with camera?

I normally clone the arms and put them in camera and weld them to the real arms. Example

player = game.Players.LocalPlayer

local arm = player.Character["Left Arm"]:Clone()
arm.Parent = game.Workspace.CurrentCamera
local weld = Instance.new("Motor6D", arm)
weld.Part0 = arm
weld.Part1 = player.Character["Left Arm"]

This will clone the arm. And weld it to the real one
