canted sights
gas tube sometimes bent
magazine wobble (the 10/63 fixed that)
only likes certain mags for some reason
just be warned that when you buy a wasr your going to be taking a gamble. looking over it will reduce the chance of getting a piece of trash, but all in all you need to fire the thing to be certain. i own a wasr 10/63, i have had no problems with it, but you will find all over the internet about people who beg to differ. if you want a well built, sturdy AK clone your best bet is to grab up something built by arsenal inc. Dont get me wrong, i like the wasr and wouldnt trade it, but im eventually going to grab something a little higher on the ladder
