Hi guys I'm currently building a custom DPMS .308 rifle. For a barrel I'm looking for a 24" bull barrel with fluting and finished in BLACK. Also, maybe even have the end threaded for a break. As far as i can find there is everything but black. I don't like the shiny stainless. Does anyone on here know of such a barrel offered by a company or possibly a company that does custom barrels? Quite frankly I'm not looking for a cheap barrel. I am looking for a barrel that is high quality with these specs. Any ideas?
