All the Romanian AK rifles imported after the date of this ruling
http://www.atf.gov/firearms/assault/treasrelease.htm
could only use single stack 10rd mags. Century Arms converted AK rifles to use high capasity mags and added 5 US made parts which are the trigger,sear,hammer,gas piston,and pistol grip. So any model of Romanian AK rifle converted by Century Arms has only 10 imported parts and legal to use with any hi cap mag.
They imported the model WASR in 1998,the SAR-1 in 1999 to 2003,and the WASR-10 in 1999 and 2004. They converted very few of the WASR-10 rifles to use hi cap mags till the 2004 imported rifles.
The quality control slipped on the WASR rifles and a few started showing up with the front sights canted that is pressed on the barrel off center slightly leaning to one side. But the quality control really started going down hill with the SAR-1 rifles as a larger percentage of owners reported canted front sights,rear sights,and/or gas blocks on their new rifles. Here is how to fix the problem

As you can see from the second picture the front sight has been adjusted all the way to one side to try and make up for the front sight being canted. Some rifles this will work but most it will not.
There is also info on how to fix a canted gas block and the mag well of WASR-10 rifles.
The best thing to do is look the rifle over real close to make sure everything is on straight before buying it.
