I'm going to build a 224 valkyrie in a bolt gun. And before you try talking me into a 22 arc, I've been shooting a valkyrie in an AR for a long time and have tons of components. I have an action, I'm in need of a barrel. An 8 twist, i want to be able to finish it at 20", stainless preferably. CF is ok but a stainless #4 ish..... let me know what you have, cash in hand! Thanks, Jim
