I had one (had to sell it back when the bottom fell out in 08) and am looking at re-acquiring one. It was very solid, no issues.
This time I will put an Ultimak gas tube rail on it though. The eyes ain't what they were.
And as far as mag wobble, I never used anything but surp and never noticed an issue. but then again, it's a stamped AK, I expect it.
