This guide details a DIY modification for the SKS bolt face to address popped primer issues. By carefully grinding down a raised area on the bolt face and then slightly countersinking the edge, the presenter aims to prevent the bolt face from contacting the primer prematurely, which is identified as the cause of bent or broken firing pins. The process requires basic gunsmithing tools and a methodical approach to avoid altering headspace.
