You also might want to check with your gunsmith to see if he has any barrels you'd be interested in he may even be able to get the barrel you want cheaper. Also places like Numrich, Century arms and Sarco have Mauser barrels. At the time this was wrote Sarco had 26inch Parker Hale .308 heavy barrels for 30 some bucks and century arms had 30-06 barrels around 40 bucks. : )
