Shooters,
I once dogged KAC, implying they were not all that, but that Government contracts were their primary goal without much in the way of actual firearms manufacturing competence. I was wrong. One sure way to recognize a high-performance oriented big chassis AR is the size of the firing pin - ignoring the obvious fallacious pun - that is to say, the smaller the firing pin, the less the likelihood of primer extrusion such as is, at times, the experience with other, similar, big chassis AR rifle's firing pin and bolt face holes. KAC is the right size, on the small side, which is correct in my experience as a shooter whose rifles' performance was impaired with such primer extrusion into a firing pin hole size of .078" as the weak link in the pressure issue. Thanks, KAC, for making a good bolt, like Armalite, having pin hole sizes of @.065" that functions without the extrusion impediment to velocity in big AR's.
