Oh, I see. I thought you did it custom.
If I had to take an educated guess at it, I would say that it's probably just to create a "venturi", so as to get some pressure gradient that corresponds to a given hole size, but without drilling a hole that risks touching the high spots of the rifling. Small hole through bore, but venturi effect entering the gas block.
