My arsenal seems to be putting dents in the casings when it ejects them. I can't quite figure out what they are striking on the way out of the chamber. I attached a pic. Any ideas and is this normal?

It is the AK kiss......normal Google it there are some mods you can do but your shooting steel cases just let it go

AKs mangle brass. If you are like me, you owned an AK clone in order to shoot cheap ammo. Don't worry about the brass unless you want to reload.

This is normal for AK's. They hit the receiver cover on the way out. You can shoot steel cased ammo or try some weather sealing strips on the receiver cover by the ejection port to keep it from dinging the cases. I've reloaded brass dented by my AK like this but they were NATO spec 7.62x51 brass which is slightly thicker than .308.

If you were shooting brass case ammo, I would see a reason for concern. As it is, I don't.

Thanks guys. I shoot the cheapo steel stuff so i'm not really concerned about reloads.
