[QUOTE="SSgt G Cody, post: 2347119, member: 113303"] As I understand it, lapping and polishing is usually needed only on lower quality factory rifles to remove any machining "Flash". This is usually on a new rifle that has poor accuracy! Almost all high quality custom barrels are lapped at the factory. The chamber is only semi-polished. The feed ramp is usually highly polished. I believe the polishing agent is Alumina (Aluminum Oxide). Grit size is 360, 600, then 1000, according to my gunsmith friend! [/QUOTE]
