Destructo6 is correct. The thing to watch with the US/Maadi is the front sites. Some are hopelessly canted. Also some models will take hi-caps and some will only take 10 rd. klintonistas. Also, the furniture is horrendous and the metal finish has this thick black paint on it that will flake off with ease. This being said, I had the MISR 90 and it was a terrific little AK, not one failure thru app. 5000rds.
The preban Maadis were among the best AK's made. Hope this helps you a bit.
