Starbuck, unless you have the uber-rare 8MM Mauser version, extractors or bolt assys can be had from Numark. I had to buy a new bolt sleeve recently (cracked where the safety attaches) and was suprised they had as much stock as they did for these rifles. Only cost me 20$, an extractor is probably about 10$
