Ya wanna run mild steel cased ammo without eventually doing damage to the firearm? Get one with a chrome lined chamber.

Yeah I get that but underneath the dust cover of an AK there is a lot more room for mud to go to and not be in the way of the mechanical parts. On an AR there is far less room and the mud gets packed right in with the mehanical and moving parts.

Lotsa mud where you live?
