    To make this claim,you would have had to know the primer was high before the round was chambered. Not impossible but certainly improbable.

    I was present when an AR blew up a couple of years ago. Examination of the remaining ammunition revealed several cartridges with high primers. We concluded the rifle fired due to a high primer. The evidence is destroyed in such cases so you have to draw conclusions indirectly. I can't cite a study where high primers were shown to cause out of battery discharges but it is accepted wisdom that they can and will.

    Blown primers are a very serious and dangerous malfunction and when one occurs, just one, you really should stop shooting until you have determined what the problem is. It seems to me that the design of the AR is very good at protecting a shooter, particularly a right handed shooter from consequences of blown primers and blown cases. Other rifles, the M1 and M1A for example can put an eye out when this happens.
