Issues with firing pin size - Faxon Firearms .308 9310 Bolt Complete

I bought this because the Faxon manufacturer comment said on the review that it uses standard DPMS firing pins. But that IS NOT TRUE, the firing pin hole is too small. I cannot actually find a firing pin that works with this, is it proprietary? I've emailed and called Faxon and cannot get an answer. So this bolt is useless to me
