In the last 20+ years I have owned 15-20 including SAR 1's, WASR's, Yugos, Chinese, Arsenal, Egyptian, and Russian. All were 100% EXCEPT the big bucks Arsenal. It was junk.
The WASR will be the cheapest, as the price goes up from there, you just get 'bling' NOT more reliability.
Stick with eastern European metal mags, $12-$14 from a lot of places, CDNN, Cheaper than Dirt, etc.
