Well, the blued finish is fairly thin and tends to rust if you neglect it and the standard thumbhole stock sucks.
Otherwise, it's probably one of the best AKs. The entire bolt and carrier are hard cromed, the firing pin is spring loaded so slam fires are non-existant, the trigger is double hooked and a bit smoother than ROMAKs, the mag paddle is large, and probably a few other tidbits I forget. Mine has proven to be pretty darn accurate and typically AK reliable.
