94 is the year of production. The finish on the receiver does not look correct to me. I have had three of these and none of mine had a glossy thick finish, all matte finish. Since it came with a thumbhole stock and has already been altered, I would refinish it. I used AK USA and he does a great job (not cheap, but you get what you pay for).
FYI, you also need to check the forward Y stamp on the left side of the receiver (if it has one). If it has a rivet in the center of that stamp and it is just there to close up a drilled hole, then you have one of the recalled rifles. Some of the first batch of imported rifles had the center of the Y stamp drilled for the full auto pin and then the Egyptians just placed a rivet in the hole to close it up. ATF recalled these as they considered the drilling of the hole as making the rifle a machine gun. My first Maadi was one of these and I had to send it back to the importer for exchange. They made a big deal about trying to get these back; my dealer contacted me with a special letter from the Importer and ATF about the issue. I do not believe that they got them all back and some are still out there. I always check for this on all of the early pattern AAC/Intrac imported rifles.
