That's a curious thing - because the face of the bolt has fully engaged and slammed against that primer in that bottomed out round, before the bolt starts to rotate. No discharge (or you have an OOB Kaboom, which is extremely rare with an AR15). The firing pin is stopped by its tail on the firing pin retaining pin; long before it can touch the actual primer, and is knocked back.
You are correct, unless the manufacturer product is insanely out of spec. It takes very little for bolt bounce in full auto, to induce a light strike malfunction. The Stoner AR is a very well designed and safe operating system. Excellent description and explanation, thanks for sharing.
