Mine is quite accurate although the sights aren't the best.
The trigger is sort of weird, it's a bizarre 2 stage afair that is almost like a sort of set trigger. If you pull very gradually through the first stage you'll feel a sort of a give at the end of that stage and it's like the trigger is now set. It may be some sort of tactile illusion, but at that point it feels as if a lighter short pull fires the gun from that position. However, it's not really a set trigger because if you release it, the trigger goes all the way back forward.
I've had trouble using mine consistently as anything other than a single shot. I don't know if I've only tried rounds that the gun doesn't like, but for whatever reason, I can't get it to feed consistently from the magazine. I also don't know if that's common or if it's just my rifle.
I had some ejection issues initially but figured out what the problem was and remedied it. I sharpened the shoulder on the ejector so it would catch properly on the bolt latch. As I recall, the ejector floats in the bolt but as the bolt is retracted, a shoulder on the ejector catches on the bolt latch. The ejector's shoulder had rounded off and it wasn't catching reliably on the bolt latch.
I think I paid about $60-$65 for mine (shipping & fees included) a few years back when they were being imported in large numbers and were really cheap, so I can't complain.
The front sight elevation can be adjusted with a standard elevation adjuster for an AK front sight. Be sure to select the proper rear sight "leaf" when zeroing the rifle. Windage adjustment requires drifting the entire rear sight assembly.
