SAR-3's kick ass!! I've got 6 of them.
I've owned 1 of almost every AK variant available to the general public- I've had multiple copies of many. (Chinese,Egyptian, Yugo, Bulgarian, Galil, Valmet, Saiga).
After 25 years of owning and shooting AK's, I only have Romanian guns now. Everything else is over rated, over priced, not as accurate as the Romanians and no more reliable.
Weiger magazines are a MUST and I've got plenty of these too!! (NOT FOR SALE)
The only problem I've every had was trying to shoot NATEC polymer cased ammo. Damn near blew my face off when a round detonated in the receiver while being chambered. The top cover stayed on, but is slightly bent and rattles a bit. I had brass (from the case head) in my left forearm and face, and there was brass and molten polymer splattered all over the inside of the receiver and magazine.
I loaned the rifle and magazine to Natec for them to inspect after they tried to buy it from me. They tried to cover their asses with a b.s. story of YOUR GUN IS JUNK. Got the rifle back and it's been shooting fine every since. I didn't have to replace any parts, I just cleaned it out a bit. In fact, it's mounted on the protective screen in my patrol car right now and I just qualified with it yet again last week.
