How do I remove fake arms?

I got some script off a minion to make barrel rotate on a different gun, but when I inserted it into my other script, it gave it fake arms. Help please

local arms = nil
local torso = nil
local weld33 = nil -- right arm
local weld55 = nil -- left arm
local welds = {}

wait(0.01)
arms = {Tool.Parent:FindFirstChild("Left Arm"), Tool.Parent:FindFirstChild("Right Arm")}
torso = Tool.Parent:FindFirstChild("Torso")
if arms ~= nil and torso ~= nil then
local sh = {torso:FindFirstChild("Left Shoulder"), torso:FindFirstChild("Right Shoulder")}
if sh ~= nil then
local yes = true
if yes then
yes = false
sh[1].Part1 = nil
sh[2].Part1 = nil
falsearm1 = arms[1]:clone()
local mesh1 = Tool.Larm:clone()
mesh1.Parent = falsearm1
local armweld1 = Instance.new("Weld")
falsearm1.BrickColor = BrickColor.new("Light orange") -- this is the arm colour incase u want to change it
falsearm1.Parent = Tool
armweld1.Parent = falsearm1
armweld1.Part0 = falsearm1
armweld1.Part1 = arms[1]
falsearm2 = arms[2]:clone()
local mesh2 = Tool.Rarm:clone()
mesh2.Parent = falsearm2
local armweld2 = Instance.new("Weld")
falsearm2.BrickColor = BrickColor.new("Light orange") -- this is the 2nd arm colour incase u want to change it
falsearm2.Parent = Tool
armweld2.Parent = falsearm2
armweld2.Part0 = falsearm2
armweld2.Part1 = arms[2]
local weld1 = Instance.new("Weld") -- left arm
weld55 = weld1
weld1.Part0 = torso
weld1.Parent = torso
weld1.Part1 = arms[1]
weld1.C1 = CFrame.new(-0.35, 2, 0.6) * CFrame.fromEulerAnglesXYZ(math.rad(295), 0, math.rad(-90))
welds[1] = weld1
local weld2 = Instance.new("Weld") -- right arm
weld33 = weld2
weld2.Part0 = torso
weld2.Parent = torso
weld2.Part1 = arms[2]
weld2.C1 = CFrame.new(-0.75, -1.2, 0.35) * CFrame.fromEulerAnglesXYZ(math.rad(-70), math.rad(-35), 0)
welds[2] = weld2
end

print("sh")

print("arms")
