Agreed that you should part it out. But I think that the barrel is trashed as well. Something wrong with chamber which may be why the face of the bolt was opened up with a dremel to accommodate the case deviation. As Guntech says...98 bolt is quite different: ZKK located the ejector slot on the bottom of the bolt face rather than cutting a slot in the left lug like an '98 (which was considered to weaken the '98 action) among several other ZKK 'improvements'.
