Century has a few varieties out there now. Which were you interested in?
The early WASR rifles often had canted sights, canted gas blocks, and mag wells that were loose and allowed the mags to wobble more than "normal". Some of the later assembled ones seem to have been assembled a bit better.
Not too familiar with their more recent offerings.
As far as my understanding is the 10/63 is one of the better AK rifles you can buy on today's market. I have not had much experience with them. Only heard praising from a lot of people. I am more of the Yugo AK guy.
Just got back from test firing the WASR 10/63 that I just got in a trade and cleaned up. It has straight sights and ran a good mix of FMJ, HP, and SP ammo. Sights were regulated well for windage but a touch low.
