Scotch bright on steel does nothing but polish it. You won't remove any material to make a difference. And the barrel extension is not the place to focus your attention. Just be sure it's free of any surface defects like burrs, & dings. I would rub a little scotch bright on the ID of the receiver and use a little bit of lube.
