protect steel parts from rust. Actally what i really want to pull outta this thread is your opinion about ARs (barrel) finish. i mean, do you guys think 'black oxide' is a good way to protect a barrel from getting rusted?.
Are there any others? (used in ARs)
how about the steel? is it likely to get rusted?
