[Unclenick]

Even boxer primers sit about -0.004" from flush, normally, and if they are properly reconsolidated to set the bridge (the anvil compressed into the priming mix by 0.003"). This is especially important in self-loaders with floating firing pins to mitigate the possibility of slamfires. At the same time, because the AR firing pin floats, there is no spring fighting to return it to the bolt, so as long as his firing pin extension is adequate, there should be no problem there.


KWS,

Have you tried firing another set of rounds, but hitting the forward assist after each round chambers and before firing it?
