The action of the solution used to rust blue the barrels, causes them to "rust" in a controlled manner.This causes microscopic "pits", which both gives the satin finish and wearability.The final polish is usually with worn 320 grit cloth.A high polish doesn't want to rust,especially if hard metal(like a bolt shroud),sometimes requiring repolishing with new 320.I never tried to get a shiney finish, so I can't say with authority, but a coat of paste wax after normal blue, may do it.

Mike,
I polish out to 600 grit quite often.....also have gone to 1000 grit on some......the number of applications generally dictates the darkness, i.e., blue or black, and the grit generally dictates the gloss......this has been my experience, but I use a boiling water rust process, not a sweat box...A) more control...B) not effected by the weather, i.e. humidity, heat, cold...C) better wear quality and durability...D) easier handling and carding...E) better results consistently.........this is my opinion based on experience.......
Best,
