price range on an AK can go from 400-1200+
size, Short, Regular or long? (AKSU, AK, RPK?)
caliber? 5,45 or 7,62 and dont count out the Saiga's come in all differnt flavors.
stock? side folding, under folding, fixed?
ban features? no ban features ie threaded muzzle, bayo lug, high cap mags, pistol grips.
going on your information with no price range or variying price range i would go with an Aresnal SLR 107 on the high end, or a WASR 10/63 on the lower end.
Aresnal=mid to high priced AK, some minor issues (nothing aresnal cant/wont fix under warrinty) very high quality.
Century WASR 10/63. low priced AK, same issues as the Aresnal minus maybe finish problems + mag wobble (on some). no idea about the century Warrinty. fit/finish meh.
good luck! do a search of the AK board on here lots of good info!
