    A nitrided SS barrel will have a longer life span than a non-nitrided SS barrel but you aren't going to get the same durability as a nitrided cut or buttoned 4150 or nitrited CHF "machine gun steel" barrel. Durability relies on both the treatment/lining + the base metal. If you have a weaker substrate metal you are going to get much faster barrel erosion once the propellant gasses eat through the treatment/lining in the thoat area and leade of the rifling.

    Also b/c the OP asked, in my experience Green Mountain barrels are overgassed. .080 for a 11.5" carbine. Moreover, their customer service told me to pound sand when I asked them why they chose that GP size.

    Thanks vicious..I am wanting accuracy over durability for this build. And I appreciate the word on GM, Hulkstr8.
