I've seen several broken firing pin retaining pins (FPRP), nearly all from a single manufacturer (usual suspect). Some others were from elsewhere lower-end. All were broken in the middle. All were in unshrouded carriers and subject to hammer drag.
Makes sense. My LWRC carrier is unshrouded and with the extra recoil and bolt velocity, I can see why. Hopefully the KNS pin will handle the abuse.
