I have one of those in my pre-forward assist, original Colt chrome bolt carrier for my Colt Model 605 project. That is the original design on the late 1950's Armalite AR15. Did your cotter-pin style firing pin retaining pin actually bend from firing pin impact? If so, that is a sign of hot loads...ask me how I know...I've bent both types in my .260 AR10 during load development towards the hot end.
