Stainless Steel, 26 inch fluted, with weaver base, 1 in 12 inch twist and with approximately 200 rounds fired. Hornady 50 grain V-Max Superformance is very accurate in this barrel. Bought this barrel new and it is in great shape but just don't use as I have a bolt gun in that caliber that gets used when I want to shoot a 22-250. $350 cash-firm. Please call with questions or to arrange a time to take a look.
