Re: Has anybody actually had a buffer tube failure in an AR?
No problem! This is one of those super valuable oldschool tricks that being lost to time. Works on all steels as far as i know.
This is also how traditional firearm blueing is done. Rust, boil, card(buff), repeat as desired. Finish with linseed oil or something similar.
