Look on gunbroker, firearms parts barrels. Currently TG international is selling utg 7.62x54R chambered machinegun barrels. I won one and it cost $87 plus about 20 or so for postage. If you cut off the roughly 2" for the origional chamber will still give you about 22" of brand new barrel to play with. Only one downside, this thing is massive which translates into a lot of lathe time getting her on a weight reduction program. Must weigh about 15 lbs. One section is about 1.5" in diameter. These are brand new bbls set up for installation on the moisin nagant rifles. Just a suggestion. Frank
