Barrel is a 26" 1:8 twist X Caliber 1.2" straight blank chambered in 6.5cm(saami chamber) by Spartan Precision. Round count is just under 2k, don't know exact count, but it's just under 500(I have 485 left, lost some along the way) pieces of brass with 4 firings on all, so between 1940 and 2000 rounds. Still has life left for a match or trainer barrel. Mechanical ejection and cut for AW mags $1500, basically the price of the action with a free barrel. Can't get prefits for this action as it has a conical breech and bolt face. 90° bolt. Round count is the same on the barrel and action. Incredibly smooth.
