Some observations regarding gas entering the firing pin hole on the RAR. There are (3) holes (qty=3, or 3, or three
) between the lugs on the bolt head. Two are directed towards the vent holes on either side of the receiver, the third vents to the thru-hole for the front action screw (i.e. blind hole and blocked), but there is a larger hole in the bolt body that vents to the magazine.
The pick points to the "functional" vent holes.

It seems that gas entering the bolt body would be vented well. The tail end of the bolt appears to be sealed. I had (2) pierced primers (qty=2, or 2, or two
) and never felt anything, but have never experienced anything worse.
