Wow, Your friend has a problem. They are out of manufacture and the only avenue is to by a rifle that is a "dog" gun, Damaged or unusable for anpther reason and salvage the bolt and hope the headspace is ok. There are gun parts savers such as Numrich Arms in WEst Hurley NY, and Pennsylvania Gun parts - Good luck. I can remember refusing to buy one years ago because they were starnge looking but seemed to shoot OK. The Bolt was always the weak link in the design.
