my brother has an early chinese ak, he's had it for 18yrs now and has never cleaned it, sits on the seat of the feed pickup all year long with the dog climbing over it all the time, has been it 3 wheeler wrecks, had 2 stocks put on it, never has jambed and yes about every third round comes out tumbling, which sends it wherever, he uses for everything from gophers to deer, buys the military ammo in the wooden case with the stripper clips wrapped in waxed paper tyed with a string, 1200 rds fmj to a crate, never seen one miss fire
