Not to take over the thread - but I also have a Romanian AK-47, and I have shot it a few times (maybe 70 rounds), but I have never cleaned it.
I have the gun for just fun shooting, and for SHTF/secondary home defense weapon.
From what I understand, not cleaning this gun will not impede reliability, but will it damage the gun? I have used only Wolf ammo in it so far. Also - when cleaning it, since there is no way to lock the action open, how in the world does one clean it?
Just field strip it. There is no way to lock the bolt back on an AK unless you by one of those aftermarket safeties.
You will have to clean it once in awhile, but not really for reliability.
You have to clean any gun because fouling attracts moisture and will eventually lead to rust. Don't oil the gas piston when you clean it, just wipe the crap off.
I routinely shoot my AK dirty, and I do it with my handguns too. Both my SIG and my CZ will do just fine with 500+ rounds between good cleanings. I don't do that very often, just when I first get one to prove to myself that it WILL WORK if I need it.
Just bear in mind that the more you allow to build up on it, the harder you will have to work to get it off.
