Lancaster, I cut the moisin bbl down so it would fit into the headstock of my lathe. Used a parting tool to cut a groove all the way around about an eighth of an inch deep. I have a steel block with holes drilled for 1/4x20 capscrews. A few washers and set the block in my vise. Bbl stub came out with a pipe wrench. No damage to the receiver at all. Frank
