I joined the South Bay Rod and Gun club yesterday and shot just under 300 rounds of surplus 5.45 through my AK. It was a great feeling finally being able to zero my irons after building it last March at the San Diego Build party.
At home I noticed the ejector deformation and now I'm questioning my heat treatment.

Should I be concerned about this kind of wear?
