Re-lining is possible but not an easy task. The barrel has to be bored out quite thin and a 4140 blank turned to make the liner. I prefer to thread the liner for the receiver and cut off the threaded portion of the barrel. In essence, one rebarrels the rifle with the liner then installs the shell of the original barrel over it. The liner and barrel are bonded together with epoxy. The original barrel becomes nothing more than a thin sleeve over the new barrel. The job is a bit of a pain in the neck and from an economic standpoint, is hardly worth it; being roughly three times as much work as just installing a new barrel. GD
