I would also say the restored Saiga conversions are your best bet. You end up with a fairly true Russian rifle. Krebs does nice work, as does AK-USA.
If you expect MOA accuracy from an AK you will be disappointed. I've most all the variations and better than 3MOA is the exception not the rule. 4-8" groups at 100 yards is what most available ammo will give you in a "random" AK. The poor sights and trigger by AR standards don't help either.
I've had just the opposite experience. I would say that 3-4" at 100 yards would be the norm across the price range of guns I own or have owned, excepting out guns built here from kits. The guns assembled/barreled in the country of origin usually do better than the guns assembled here, or at least the guns I own/owned have.
Ammo has a lot to do with it too. If you have a lot of decent ammo, you'd be amazed at what can be accomplished. Wolf has been hit or miss all along, the old Barnaul, (especially the 125 grain soft points) which I believe is now being sold under the Brown and Silver Bear labels has always been the most consistent for me. I do have a lot of Wolf 154 grain SP's that is also very good.
The sights really are not all that bad, and you can also add a red dot if you have trouble with them. As far as the triggers go, all of my AK's triggers have been better than all but one of my AR's, and that trigger is a worked match trigger. Even the triggers that had slap were better, although eventually painful.
Theres no doubt that the AK isnt a target rifle, but its really not as bad as you often hear. Pop a red dot on it, and it will stay right up with just about anything else within reason.
