My AK spat at me the other day! It is the second time I've had gas/cinders/particles of some sort thrown at my eye from under the dust cover, while firing it! ( I think it was from the gap between the cover and the carrier spring base) I'm using eye protection now, but it's unpleasant and sure don't want to rely on having to wear glasses in an emergency. Whats the deal? I've never heard of such a thing happening.
