How do I get rid of the fake arms in this script?

I'm using turbofusions gun script but I need to replace the fake arm with the real arm. I have got the snippet of code that creates the arm: it is v 0.02

--------------------[ ARM CREATION FUNCTION ]-----------------------------------------

function CreateArms()
    local Arms = {}
    for i = 0, 1 do
        local ArmModel = Instance.new("Model")
        ArmModel.Name = "ArmModel"

        local Arm = Instance.new("Part")
        Arm.BrickColor = (S.FakeArmRealBodyColor and (i == 0 and LArm.BrickColor or RArm.BrickColor) or S.FakeArmColor)
        Arm.Transparency = S.FakeArmTransparency

        ArmMesh.Parent = Arm

        local Sleeve1 = Instance.new("Part")
        Sleeve1.BrickColor = BrickColor.new("Sand green")
        Sleeve1.Name = "Sleeve1"
        Sleeve1.CanCollide = false
        Sleeve1.Size = VEC3(1, 2, 1)

            if LWeld2:FindFirstChild("TweenCode") then LWeld2.TweenCode:Destroy() end

                    local NewX = X + 1.5 / S.AimSpeed
                    X = (NewX > 90 and 90 or NewX)

end

        return FinalHitObj, FinalHitPos
    elseif HitObj or (Dist <= 999) then
        return HitObj, HitPos

Thanks if you are gonna help.
