Welcome from another new member just down the road. I'm sure "thatoneguy" screen name must have some significance but it brings about a story I have to tell. This is a story about Grandpa's. To some it is a blessing to become a Grandpa, but obviously others dread the very thought of becoming one. So much so that when my stepson and wife had their first child, her dad threw a fit about being called Grandpa. Mr. Macho insisted that he not ever be called Grandpa. Anything... like maybe first name (just not kosher), possibly pawpaw (but reluctant), he didn't know what he wanted his grandchild to call him. So out of respect for his egotistic selfishness the family would just point and say "that guy". Guess what? For his grandchildren (now 2 of them) his name is "That Guy". I think the name if fitting!
Blueing and Browning are both forms of controlled rust. A properly browned barrel is beautiful and easily maintained. A blued barrel can transform into a browned barrel over years of use and cleaning.
