I'm getting a very expensive match grade AR barrel and I'm looking for tips to avoid the scuff marks I got last time on relatively cheap stainless barrel when installing a tight slip-on gas block with Melonite coating. The barrel past the gas block is something in the .730-.740 range and the gas block would chatter along even if slid as square as possible. I think it was the slightly burred sharp ends of the set screw holes that marked the most last time.
